The state and the subsoil: ownership of resources

Resource ownership means who owns oil and gas by law while they are still in the ground. The owner also decides who may produce them, on what terms and for what fee. In almost every country, including Kazakhstan, the subsoil (the rock below the surface, with the oil and gas in it) belongs to the state. In the wording of the Kazakhstan Constitution, it belongs to the people, and the state exercises the right of ownership on their behalf. A notable exception is the United States, where oil and gas under private land generally belong to private owners.

Why it matters

The owner of the subsoil decides several things for an investor: with whom the investor negotiates access to a field, and what exactly the investor gets (the field itself, or only the right to develop it). The owner also decides what part of the income it will take, and what obligations come with the right. These terms are part of the project's cash flow, and they often decide whether the project goes ahead at all.

Quick refresher

  • Distinguish three things. The subsoil belongs to the people, and the state exercises the right of ownership on their behalf. The subsoil use right is a temporary, paid right to use an area. The produced oil belongs to the subsoil user under the Subsoil Code, unless the Code provides otherwise.
  • Almost everywhere in the world, oil in the ground belongs to the state. In the USA, rights to oil and gas usually follow the land and can be private. A company leases them from the owner for a bonus (a payment at the start) and a royalty (a share of the oil or of the revenue), and the state, as the authority, collects taxes.
  • The state as owner wants more than income. It also wants savings for future generations, rational use of the subsoil, orders and jobs for its economy and regions, fuel for the domestic market and control over strategic areas. The goals pull against each other, and subsoil use terms are a compromise between them.
  • Resource rent is what the field earns after all the costs are paid back and the investor has the return it requires: the NPV (the value today of the future cash flows) of the project before payments to the state, at the investor's rate. Subsoil use terms divide the rent, but they do not create it.
  • The more the state takes, the less is left for the investor. When the investor's NPV falls to zero, raising the rates makes no sense: the project will not start, and the state will get nothing. The limit rate is right only for one scenario of price and costs.
  • In Kazakhstan, the contract for hydrocarbons is signed on behalf of the Republic by the competent authority, the Ministry of Energy. For strategic areas, the state has a priority right to buy the rights that are being sold. Changes of legislation that make things worse for the subsoil user do not apply to contracts that are already signed, except for tax changes and some others.
Key relationships
NPVpre-tax=PVstate+NPVinv\mathrm{NPV}_\text{pre-tax} = PV_\text{state} + \mathrm{NPV}_\text{inv}

the rent is divided between the state and the investor; the sum does not depend on the terms of the split, as long as production and costs do not depend on them

NPVpre-tax=(P−c) Qdisc\mathrm{NPV}_\text{pre-tax} = (P - c)\,Q_\text{disc}

the same rent through the discounted technical cost per barrel cc and the discounted production QdiscQ_\text{disc}, at a constant price PP

the royalty rate at which the investor is left with exactly the required return (TT is the income tax rate; the tax base is positive in all years)

Common pitfalls
  • Thinking that a company with a contract owns the field. It owns the right to use the area for a period, and the produced oil, but not the subsoil.
  • Comparing “government takes” (the state's share of the income) calculated in different ways: without discounting and on discounted flows the numbers differ noticeably.
  • Thinking that higher rates always raise the state's income. Beyond the limit of profitability the project will not go ahead, and a high payment on revenue stops production sooner.
  • Carrying American practice over to Kazakhstan: private ownership of land here does not give rights to the subsoil under it.

After this lesson you can

  • distinguish the subsoil, the subsoil use right and the produced oil, and show who owns each of them under the Constitution and the Subsoil Code of Kazakhstan
  • compare state ownership of the subsoil with private rights to oil and gas in the USA, and explain how this changes the position of the investor
  • list the goals of the state as owner (income, saving for the future, rational use of the subsoil, development of the economy and the regions, energy security, control over strategic areas) and recognise them in subsoil use terms
  • calculate the resource rent of a project and its split between the state and the investor, find the limit rate of a payment, and explain why beyond it the state gets nothing
  • describe how the subsoil regime of Kazakhstan has changed from Soviet times to the Subsoil Code, and how the rights to the seabed of the Caspian Sea are divided

The subsoil, the subsoil use right and the produced oil

When we talk about oil projects, it is easy to mix up three different things. The first is the subsoil itself and what lies in it. The second is the subsoil use right: the right to explore and produce in a defined area. The third is the oil and gas already brought to the surface. Each of them can have a different owner, and the position of the investor depends on how the law separates them.

The Constitution of the Republic of Kazakhstan was adopted at the republican referendum on 15 March 2026 and has been in force since 1 July 2026. It speaks of the subsoil in the same way as the 1995 Constitution after the 2022 amendments. Land and its subsoil, waters, flora and fauna and other natural resources belong to the people, and the state exercises the right of ownership on behalf of the people (paragraph 3 of Article 8). Land may also be privately owned, on the grounds, under the conditions and within the limits set by law. For the subsoil there is no such provision.

The Subsoil Code (the Code of the Republic of Kazakhstan “On Subsoil and Subsoil Use”) repeats this rule. It adds that the state exercises the right of ownership through the regime of state ownership, in the interests of the people. It gives the subsoil for use on the grounds, under the conditions and within the limits that the Code provides. Transactions made in breach of state ownership of the subsoil are void (Article 11). The Code defines the subsoil as the part of the earth's crust below the soil layer, or, where there is no soil layer, below the earth's surface and the bottom of bodies of water and watercourses (Article 10).

Three objects, three regimes (the Subsoil Code of Kazakhstan)
Object
The subsoil and the minerals in it
Who owns it
the people; the state exercises the right of ownership on their behalf (Article 11)
What follows
a field “in the ground” cannot be bought or sold; the state disposes of it
Object
The subsoil use right
Who owns it
the subsoil user, under a licence or a contract; for hydrocarbons, under a contract (Articles 20, 35)
What follows
temporary, paid for, within the borders of the area; transferred with the permission of the state
Object
The produced minerals
Who owns it
the subsoil user, as property, unless the Code provides otherwise (Article 15)
What follows
the company sells the oil and receives the revenue; the state takes its share through payments

In the version of the Code in force in October 2026. A state legal entity owns the produced minerals not as property, but under the right of economic management or of operational management (rights over state property that are weaker than ownership).

The Code defines the subsoil use right as a possibility, secured by law, to use the subsoil for a fee, within an allocated area, for business purposes and for a defined period (Article 17). This is a real right (a right over a thing, as opposed to a claim against a person), and it is indivisible. The rules on the right of ownership apply to it as far as they do not contradict the nature of a real right. But the object of the right is the use of the subsoil, not the subsoil itself. Under a subsoil use contract, the Republic of Kazakhstan, represented by the competent authority, undertakes to grant the right for a defined period. The subsoil user undertakes to carry out the work at its own expense and at its own risk (Article 35). The words “at its own expense and at its own risk” are the economic core of the deal: if no oil is found, the investor bears the loss, not the owner.

State ownership and private rights to oil

In almost every country in the world, oil and gas in the ground belong to the state. A notable exception is the United States, where ownership of natural resources is closely linked with ownership of land. The land, and the oil, gas and coal under it, are owned there by citizens and companies, the federal government, the states and local authorities, and Native American tribes and their members. Wide private ownership of resources is a legacy of the 19th century. At that time, the laws on the settlement of the West passed public land into private hands together with the resources.

In the USA, the rights to the surface and to the subsoil can be separated: a plot is sold, and the rights to the minerals under it are kept or sold separately. This kind of ownership is called a split estate. The opposite also happens. On part of the lands of the West that were given to settlers at the beginning of the 20th century, the federal government kept the minerals for itself. So under private land, the oil and gas belong to the state.

A company that wants to produce oil in the USA leases the rights from the owner of the mineral rights: a private person, a US state or the federal government. The owner receives a bonus when the lease is signed and a royalty, an agreed share of production or of its value. The state, as the authority and not as the owner, collects taxes. The resources of the seabed within three miles of the coast (for Texas and the west coast of Florida, three marine leagues, about 9 nautical miles) belong, as a rule, to the US states. Farther out, on the outer continental shelf, they belong to the federal government.

Two ways to own oil in the ground
Question
Who owns the oil in the ground
Kazakhstan: property of the people
the people; the state on their behalf
USA: private land
the owner of the mineral rights, usually the landowner
Question
Whom the company negotiates with
Kazakhstan: property of the people
one owner, the state, represented by the competent authority
USA: private land
each owner of rights; over a large area there can be many of them
Question
What the owner receives
Kazakhstan: property of the people
bonuses, taxes and other payments under the law and the contract
USA: private land
a bonus and a royalty under the lease
Question
The role of the state
Kazakhstan: property of the people
owner, regulator and tax collector at once
USA: private land
regulator and tax collector; owner on its own lands and on the shelf

In the USA, the state leases its own lands and shelf in the same way as a private owner does: for bonuses, rent and royalties.

The main consequence for the investor is this. Where the subsoil is state-owned, there is one owner, and the terms of access are set by law and a model contract. This owner also writes the laws and collects the taxes, so the investor makes a deal with a party that can change the rules. This is why stability of the contract and firm rules on what happens when the law changes are so valuable (the section on Kazakhstan below).

What the state as owner wants

A private owner of oil rights usually wants one thing: to get more for the oil. The state has more goals, and they pull in different directions. The Subsoil Code names as the aim of legislation the sustainable development of the mineral resource base for the economic growth of the state and the well-being of society. Among its tasks are protecting the state's right of ownership of the subsoil, observing the interests of the state and of citizens and the rights of subsoil users, and creating conditions to attract investment (Article 3).

  • Income. The state wants to get as large a part as possible of the rent, the income over and above all costs and the investor's normal profit (the next section). Subsoil use in Kazakhstan is paid for: the fee is paid through taxes and other obligatory payments to the budget (Article 8 of the Code).
  • Saving for the future. Oil is exhaustible, and income from it is in effect a sale of national wealth. The direct taxes of the oil sector go to the National Fund of the Republic of Kazakhstan. These are corporate income tax (CIT), mineral extraction tax (MET), excess profit tax, bonuses, rent tax on export, the Republic's share under production sharing and others, except those paid into local budgets. Under the Budget Code, the Fund is meant for social and economic development through the accumulation of assets, and for reducing the dependence of the economy on the oil sector and on unfavourable external factors (Articles 57, 58).
  • Rational use of the subsoil. For the owner, it is important to get as much as possible out of the field over its whole life, not as fast as possible. Hence the design documents and their state expert review, the requirements for development, and the ban on flaring raw gas except in the cases named in the Code (State regulation of field development).
  • Work for its own economy. Subsoil users must give preference to Kazakhstani personnel, and the share of in-country value in the works and services bought in a calendar year must be at least 70%, except for complex projects in the Kazakhstan sector of the Caspian Sea (Article 28). In the production period, as a rule starting from the second year, the subsoil user each year directs 1% of its production costs to the training of Kazakhstani personnel and to scientific work or digitalisation. It also directs 1% of its investment to the social and economic development of the region (Article 129).
  • Energy security. Subsoil users supply oil for processing in Kazakhstan on delivery schedules, so that the domestic market is supplied with oil products (Article 130; there are exceptions, for example for complex offshore and gas projects). Under the Law “On Gas and Gas Supply”, the state, through the national operator, has a pre-emptive right (the right to be first in line) to buy the raw and commercial gas that subsoil users sell. There are exceptions, including gas from gas and gas condensate fields.
  • Control over strategic resources. A transfer of the subsoil use right needs the permission of the competent authority, and for strategic areas the state has a priority right to buy the rights that are being sold (Articles 43, 44). The permission is refused if the transfer threatens national security, including through a concentration of rights in one person or in a group of persons from one state (Article 45).
  • The environment. Subsoil use must be environmentally safe (Article 6), and after the work the subsoil user eliminates its consequences at its own expense. This obligation does not end with the contract (Articles 54, 55).

Rent: what the owner and the investor divide

The economic meaning of owning the subsoil is the right to the resource rent. Oil has to be found, wells have to be drilled, and a field has to be built. All this costs money, which the investor could put into other business with a return at least equal to its hurdle rate (Choosing the discount rate). The rent is what remains from the value of the produced oil after all the costs are paid back together with this return. In terms of cash flow, it is the NPV of the project before payments to the state, calculated at the investor's rate.

The rent is the value of the resource itself, and so the owner has a claim on it. But the owner cannot take all of it. The investor will accept a project only if at least the required return is left, that is, if the NPV after all payments is not less than zero. Subsoil use terms decide how the rent is divided, and good terms leave the investor enough to invest.

Resource rent and its split between the state and the investor
NPVpre-tax=∑tQtPt−Ct−Ot−At(1+i)t=PVstate+NPVinv\mathrm{NPV}_\text{pre-tax} = \sum_{t} \frac{Q_t P_t - C_t - O_t - A_t}{(1 + i)^{t}} = PV_\text{state} + \mathrm{NPV}_\text{inv}
where:
  • NPVpre-tax\mathrm{NPV}_\text{pre-tax}resource rent: the NPV of the project without payments to the state, US$ million
  • QtPtQ_t P_trevenue of year tt: production multiplied by price, US$ million
  • Ct, Ot, AtC_t,\ O_t,\ A_tcapital costs, operating costs and abandonment costs in year tt, US$ million
  • iidiscount rate: the return that the investor requires from an investment with this risk, fraction
  • ttnumber of the year from the time origin (in the examples, the middle of year 1, with the flows in the middle of the year), —
  • PVstatePV_\text{state}present value of all payments to the state at the same rate, US$ million
  • NPVinv\mathrm{NPV}_\text{inv}NPV of the investor's cash flow, that is, the flow after payments to the state, US$ million

Units: any consistent currency; in the examples, US$ million in constant prices

Holds when
  • All flows are discounted at one rate ii, the one that the investor requires from an investment with this risk. The higher the rate, the smaller the rent.
  • The rent is calculated at the moment of the decision to develop. Money already spent on exploration is not in it. The full-cycle rent is calculated with that money included (full-cycle cost).
  • The equality of the split holds at any rate: in every year, the flow before payments is equal to the sum of the payments to the state and the investor's flow.
  • Production and costs do not depend on the terms of the split. In reality, a high payment on revenue stops production sooner and reduces the rent itself.

The rent is what the field earns after all the costs are paid back and the investor has the return it requires. Subsoil use terms decide how much of it goes to the owner and how much to the investor. They do not create the rent, but badly chosen terms can reduce it.

It is convenient to calculate the rent per barrel too. At a constant price, the NPV before tax is equal to (P−c) Qdisc(P - c)\,Q_\text{disc}, where cc is the discounted technical cost per barrel and QdiscQ_\text{disc} is the discounted production (technical cost per barrel). For each discounted barrel, the owner and the investor divide the difference between the price and the cost.

Worked exampleThe rent of the example project and its split
Given (assumed data)
Project
the same as in the lessons Project cash flow and Net present value (NPV): price US$50/bbl, 12 million bbl over 7 years of production
Teaching regime
royalty 10% of revenue, income tax 20% (not the law of any country)
Investor's rate ii
10% (real); the time origin is the middle of year 1, and the flows are in the middle of the year
Solution
  1. The cash flow before payments to the state, which is revenue minus capital and operating costs and abandonment, by year: −50, −90, 46, 102, 102, 84, 66, 48, 30, −12 million dollars. Without discounting the sum is 326.0 million dollars.
  2. The rent is the NPV of this flow at 10%: −50−90/1.1+46/1.12+…-50 - 90/1.1 + 46/1.1^{2} + \ldots −12/1.19=175.45- 12/1.1^{9} = 175.45 million dollars.
  3. Check through the technical cost per barrel: (50−27.787)⋅7.8987(50 - 27.787)\cdot 7.8987 =22.213⋅7.8987=175.45= 22.213\cdot 7.8987 = 175.45 million dollars.
  4. Payments to the state at 10%: PVstate=75.32PV_\text{state} = 75.32 million dollars. Royalty takes 22.5% of the rent, and income tax takes 20.4%.
  5. The investor is left with NPVinv=175.45−75.32=100.13\mathrm{NPV}_\text{inv} = 175.45 - 75.32 = 100.13 million dollars. This is the NPV of the project from the lesson Net present value (NPV).
  6. Shares of the rent: the state 42.9%, the investor 57.1%. Without discounting, the payments to the state are 115.6 of 326.0 million dollars, which is 35.5%.
Answer: The rent of the project at US$50/bbl and a rate of 10% is 175.45 million dollars. The teaching regime gives 42.9% of it to the state and 57.1% to the investor.

What it means. The two “government takes”, 35.5% without discounting and 42.9% on discounted flows, do not contradict each other. The investor puts 140 million dollars in during the first two years, while the state receives payments only with production. Discounting reduces the rent by 46%, but the payments to the state by only 35%, so the discounted share of the state is higher. When comparing the terms of different projects or countries, always say how the government take was calculated. The data in this example are assumed for illustration.

How much can the owner take? As long as the investor's NPV is positive, the project has a rent that the investor is ready to share. If we raise one payment, for example the royalty, the state's share grows and the investor's NPV falls. At some rate the NPV becomes zero: the investor gets exactly the required return and nothing above it. This is the limit rate.

The limit royalty rate
rlim=r0+NPVinv(r0)(1−T) P Qdiscr_\text{lim} = r_0 + \frac{\mathrm{NPV}_\text{inv}(r_0)}{(1 - T)\,P\,Q_\text{disc}}
where:
  • rlimr_\text{lim}royalty rate at which the investor's NPV is zero, fraction of revenue
  • r0r_0the royalty rate in force, fraction of revenue
  • NPVinv(r0)\mathrm{NPV}_\text{inv}(r_0)the investor's NPV at the rate in force, US$ million
  • TTincome tax rate, fraction
  • PPprice at the field, constant, US$/bbl
  • QdiscQ_\text{disc}discounted production at the investor's rate, million bbl

Units: US$ million, US$/bbl, million bbl; rates as fractions

Holds when
  • Royalty is charged on revenue and is deducted from the income tax base, so each point of the rate costs the investor the share (1−T)(1 - T) of its present value.
  • The income tax base stays positive in all years of production. If losses appear, the tax saving is carried forward to future years, and the formula gives too high a limit rate.
  • The price is constant, and production and costs do not depend on the royalty rate.

The denominator is what each unit of the royalty rate costs the investor, and the numerator is how much rent the investor still has. Their ratio is how much more the owner can take before the investor gives up the project.

Worked exampleThe limit royalty rate and the oil price
Given (assumed data)
Project and rate
as in the previous example: US$50/bbl, ii = 10%, the investor's NPV at a royalty of 10% is 100.13 million dollars
Discounted production QdiscQ_\text{disc}
7.8987 million bbl
Income tax TT
20%, unchanged; only the royalty rate changes
Solution
  1. One percentage point of royalty is 0.01⋅50=0.50.01\cdot 50 = 0.5 dollars per barrel. At 10%, this is 0.5⋅7.8987=3.9490.5\cdot 7.8987 = 3.949 million dollars.
  2. Royalty reduces the income tax base, so the tax falls by 0.2⋅3.949=0.7900.2\cdot 3.949 = 0.790 million dollars, and each point costs the investor 3.949−0.790=3.1593.949 - 0.790 = 3.159 million dollars. Exactly the same amount is added to the payments to the state.
  3. The limit rate: rlim=0.10+100.13/(0.8⋅50⋅7.8987)r_\text{lim} = 0.10 + 100.13/(0.8\cdot 50\cdot 7.8987) =0.10+100.13/315.95=0.10+0.3169= 0.10 + 100.13/315.95 = 0.10 + 0.3169, that is, 41.69% of revenue.
  4. Check with the project model, year by year: at this rate the investor's NPV is zero, its IRR is exactly 10.0%, and the income tax base in the weakest years, the 3rd and the 7th, is still positive, 0.65 million dollars, so the formula applies. The state gets the whole rent, 175.45 million dollars at 10%, and without discounting 82.1% of the flow before payments.
  5. At a price of US$40/bbl and the same rate: in years 3, 6 and 7 the tax base is negative, the loss is carried forward to the following years, and the investor's NPV is −37.1 million dollars. The project will not start, and the state will get nothing. With a royalty of 10%, the investor would be left with 43.3 million dollars and the state with 53.2 million dollars of discounted payments. The limit rate at this price is 27.1%.
  6. At a price of US$60/bbl and the same rate: the investor is left with 36.8 million dollars of NPV over and above the required return. The limit rate at this price is 51.4%.
Answer: At US$50/bbl, the owner can raise the royalty to about 41.69% of revenue and take the whole rent. But at US$40 this rate makes the project loss-making, and at US$60 it leaves the investor with 36.8 million dollars over and above the required return.

What it means. The limit rate is a border, not a target. The owner does not know future prices, costs and reserves, and a rate “on the edge” for one scenario turns out to be prohibitive for another. Rates with a margin leave part of the rent to the investor, but they let the project survive bad years. In good years the state loses part of its income. This is why states combine payments of different kinds (upfront, on revenue and on profit) and make some of them depend on the profitability of the project. The lesson Petroleum fiscal systems and taxation shows how this works. The data in this example are assumed for illustration.

Split of the rent between the state and the investor depending on the royalty rate010203040050100150200Royalty rate, % of revenuePresent value, US$ million41.7%rent 175.5investorstate

Graph: the horizontal axis is the royalty rate from 0 to 45 per cent of revenue, the vertical axis is the present value in million dollars. The horizontal dashed line is the rent, 175.5. The rising line is the payments to the state: 43.7 at a zero rate and 75.3 at 10 per cent. The falling line is the investor's NPV: 131.7 at a zero rate and 100.1 at 10 per cent. The lines cross at about 14 per cent, where each side gets 87.7. At 41.7 per cent the line of the state reaches the rent and the line of the investor reaches zero; a mark is placed there.

CalculatedThe split of the rent of the example project at US$50/bbl and a rate of 10%, depending on the royalty rate (income tax 20%). The payments to the state grow, the investor's NPV falls, and their sum is always equal to the rent, 175.45 million dollars. At 41.7%, nothing is left to the investor over and above the required return. At a higher rate, the project will not start.

The owner can receive part of the rent even before the first oil. At a hydrocarbon auction in Kazakhstan, the winner is the participant who offers the largest signature bonus (a payment for the right itself, made at signing; Article 100 of the Code). The investor cannot offer more than the project is worth to it at the required rate, with all payments and the bonus itself taken into account. Otherwise its NPV becomes negative (Net present value (NPV)). Competition pushes the offers towards this limit. But for exploration areas the bonus is paid when nobody knows whether there is any oil, and the whole risk of failure lies with the investor. So the offers take the probability of success into account (Expected monetary value and preference theory). The lesson Licences and contracts for subsoil use explains how auctions and contracts work.

How state ownership sets the terms: Kazakhstan

The general logic is that the owner sells not oil but the right to produce it, and takes its share of the rent through payments. In Kazakhstan, this logic is written into the Subsoil Code and the laws connected with it. Below is what follows directly from state ownership. The lessons Licences and contracts for subsoil use, State regulation of field development and Petroleum fiscal systems and taxation cover in detail how a company gets the right, how development is regulated and how taxes work.

  • Who represents the owner. The Government designates the competent authority, the central state body that represents the interests of the Republic in the field of subsoil use (Article 60). For hydrocarbons, this is the Ministry of Energy. It holds auctions, grants and terminates the subsoil use right and monitors the performance of contracts. Contracts are drawn up on model forms. They may depart from them only in the cases and within the limits that the Code provides (Article 36).
  • Which areas, and to whom. The areas for auctions are set by the State Subsoil Fund Management Programme. In drawing it up, the state takes into account national, environmental and energy security, the country's needs for minerals and the development of the regions (Article 70). A right to hydrocarbons is awarded at an electronic auction, where the largest signature bonus wins. Without an auction, by direct negotiations, only the national company in the field of hydrocarbons (a national oil company) can get the right. This is a joint-stock company whose controlling stake belongs to the state or to the national managing holding. For large fields, its share in the contract must be at least 50% (Articles 100, 103).
  • For how long. The right is temporary. The exploration period is up to 6 years (up to 18 for complex projects), and the production period is up to 25 years (up to 45 for large fields). From the day the contract ends, the area is considered returned to the state. The competent authority decides whether to eliminate the consequences of the work, to mothball the area for another subsoil user, or to hand it over in trust management to the national company (Article 107).
  • The fee. The fee for the use of the subsoil is taxes and other obligatory payments under tax legislation (Article 8). These are the signature bonus, the payment for reimbursement of historical costs, mineral extraction tax, excess profit tax, rent tax on export (from 2027 it is not charged on oil produced by payers of mineral extraction tax, Article 746 of the 2026 Tax Code) and corporate income tax. Under production sharing agreements, there is also the Republic's share in production.
  • Stability. Changes of legislation that make the results of the subsoil user worse do not apply to signed contracts. The exceptions are changes in the fields of national security, defence capability, environmental safety, public health, taxation, customs regulation and protection of competition (Article 36; for complex projects there is an exception for export duties). So the tax terms of most contracts change together with the Tax Code. A stable tax regime is kept for production sharing agreements signed before 1 January 2009 that passed the mandatory tax expertise (a state review of the tax terms), and for contracts approved by the President. It covers the taxes whose stability is expressly stated in them (Article 755 of the 2026 Tax Code). For contracts on complex projects, some norms of the Tax Code apply in the version at the date of signing the contract (Article 756).
  • Transfer of rights. A transfer of the subsoil use right, of a share in it and of the objects connected with the right needs the permission of the competent authority. This covers participation interests and shares of the subsoil user and of the companies that determine its decisions (except shares traded on an exchange). Intra-group and some other transactions are excepted (Articles 41, 44).
  • The priority right. For strategic areas, the state has a priority right to buy the subsoil use right that is being sold, or the objects connected with it, ahead of any other person, including those who have pre-emptive rights by law or by agreement (Article 43).
  • Review of terms. If the actions of a subsoil user in an area of strategic importance change the economic interests of the Republic in a way that threatens national security, the competent authority may require changes to the terms of the contract. This includes a contract signed before the Code. If the parties do not agree within the set time, it may terminate the contract unilaterally. On the same ground, the contract can also be terminated by a decision of the Government. The subsoil user may challenge the termination in court (Article 106).
Strategic subsoil area
An area of one of three kinds. The first has geological reserves of more than 50 million t of oil (oil in place) or more than 15 billion m³ of natural gas, confirmed by a report with a positive conclusion of the state subsoil expert review. The second is any area in the Kazakhstan sector of the Caspian Sea. The third is an area with a uranium deposit. The competent authority approves the list in agreement with the authorised body for the study of the subsoil (Article 43).
How the priority right is exercised
The question is considered together with the application for permission to transfer the right. By decision of the competent authority, the national managing holding or the national company buys out the right or the share, at a price and on payment terms no worse than those stated in the application. If the right is transferred free of charge or contributed to the charter capital, it is bought at the market price (Article 46).

Details and dates are in the text below.

The Soviet period. The 1977 Constitution of the USSR placed land, its subsoil, waters and forests in the exclusive ownership of the state (Article 11). State organisations explored and developed the fields. The giant Tengiz and Karachaganak fields were discovered in 1979. Gas production at Karachaganak began in 1984, and in 1985 the state production association Tengizneftegaz was created to develop Tengiz.

Sovereignty and the first deals. The Declaration on the State Sovereignty of the Kazakh SSR of 25 October 1990 declared land and its subsoil the exclusive property of the Republic and the basis of its sovereignty. The Constitutional Law “On the State Independence of the Republic of Kazakhstan” of 16 December 1991 repeated this (Article 11). To develop the largest fields, the new owner began to attract foreign companies. On 6 April 1993 an agreement was signed to create the Kazakh–American joint venture Tengizchevroil to develop Tengiz, and from 1992 negotiations were held on production sharing at Karachaganak.

The decrees of 1995–1996. The Decree “On Oil” of 28 June 1995, which had the force of law, declared all oil in its natural occurrence the exclusive property of the Republic. It left it to the contract to decide who owns oil that has been brought to the surface. The Constitution adopted on 30 August 1995 placed land and its subsoil in state ownership (Article 6). The Decree “On Subsoil and Subsoil Use” of 27 January 1996, which also had the force of law, built the system of “licence plus contract”. The subsoil use right arose on the basis of a licence, and exploration and production were carried out under a production sharing contract, a concession, a service contract, a joint activity contract or another kind of contract. On 18 November 1997 the production sharing agreement for the North Caspian was signed, and under it the Kashagan field was discovered in 2000. In November of the same year, the final production sharing agreement for Karachaganak was signed, for 40 years. In 1999 the chapter on licensing of exploration and production was removed from the decree: the subsoil use right came to be granted by signing a contract, as a rule after a tender.

The end of new production sharing agreements. From 1 January 2009, the type of contract “on production sharing” was removed from the laws on oil and on the subsoil. At the same time, the 2005 law on production sharing agreements in offshore oil operations lost force. The agreements that were signed earlier remain in force. Both laws of 1995–1996 (the decrees have been called laws since 2004) were replaced by the Law “On Subsoil and Subsoil Use” of 24 June 2010.

The Subsoil Code. The Code “On Subsoil and Subsoil Use” of 27 December 2017 has been in force since 29 June 2018. The 2022 amendments to the 1995 Constitution wrote that the subsoil belongs to the people, and that the state exercises the right of ownership on their behalf. Article 11 of the Code was changed accordingly. The Constitution adopted at the referendum of 15 March 2026 and in force since 1 July 2026 kept this wording (paragraph 3 of Article 8).

Whose seabed: the shelf and the Caspian

On land, the borders of the subsoil coincide with the state border. When production moved onto the shelf, rules were needed on who owns the resources of the seabed. For seas connected with the world ocean, these rules were set by the United Nations Convention on the Law of the Sea (UNCLOS) of 1982, which came into force in 1994.

  • In the territorial sea, no wider than 12 nautical miles (22.2 km) from the baselines (the coastal lines from which the zones are measured), the sovereignty of the coastal state extends to the waters, the seabed and the subsoil.
  • In the exclusive economic zone (EEZ), no farther than 200 nautical miles (370 km) from the baselines, and on the continental shelf, the state has not sovereignty but sovereign rights: to explore and develop the natural resources of the seabed and the subsoil.
  • The rights on the shelf are exclusive: if the coastal state does not itself explore or develop its resources, nobody may do so without its express consent.
  • The boundaries of the shelf between states with opposite or adjacent coasts are set by agreement on the basis of international law.

The Caspian Sea has no natural connection with the world ocean, and its status is set by the Caspian states themselves: Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan. Before 1991 there were two coastal states. The five states signed the Convention on the Legal Status of the Caspian Sea in Aktau on 12 August 2018. Kazakhstan ratified it in 2019. It comes into force when the depositary (the state that keeps the treaty documents), Kazakhstan, receives the fifth instrument of ratification. Under the convention, the seabed and the subsoil are divided into sectors by agreement between neighbouring and opposite states, taking into account the norms of international law, for their sovereign rights to subsoil use.

Kazakhstan has delimited its sector by bilateral agreements: with Russia in 1998 (a protocol of 2002 set the coordinates of the line), with Azerbaijan in 2001, and with Turkmenistan in 2014. Under the agreement with Russia, the seabed and subsoil of the northern part of the sea are divided along a median line modified by agreement of the parties, and the water surface stays in common use. For promising structures and fields that the line crosses, the parties have the exclusive right to joint exploration and development. For a subsoil user it matters too that any area in the Kazakhstan sector of the Caspian is strategic: the state's priority right applies to it (Article 43 of the Code).

Common mistakes and misconceptions

Wrong

“The company has received a contract, so the field is now its own.”

In fact

What it owns is the right to use the area for the term of the contract, and the produced oil. The subsoil remains the property of the people, on whose behalf the state acts. From the day the contract ends, the area is considered returned to the state.

Wrong

“The higher the payment rates, the more the state will get.”

In fact

Only while the project stays attractive. When the investor's NPV falls to zero, a further increase adds nothing, because the project will not start. Besides, a high payment on revenue stops production sooner and leaves part of the reserves in the ground.

Wrong

“The state's share in the project is 35%, and that is all that can be said about it.”

In fact

This is the share without discounting. On discounted flows, the share of the same project is about 43%, because the investor bears the early investment, while the state receives its payments later, with production. Always state the method of calculation.

Wrong

“If land is privately owned, the oil under it belongs to the owner.”

In fact

That is usually so in the USA. In Kazakhstan, land can be private, but the subsoil cannot: the right to produce oil under a plot is given only by a contract with the competent authority.

Wrong

“The state wants only income from oil.”

In fact

It also wants savings for future generations, rational use of the subsoil, orders and jobs for its own economy, fuel for the domestic market, control over strategic areas and protection of the environment. These goals are visible in the obligations of the contract just as taxes are.

In depth: advanced detail

Why rent differs, and what this means for the terms

The rent depends on the quality of the field: on its size, the productivity of the wells, the depth, the distance and the properties of the oil. For the best fields it is large, and for the worst it is close to zero. So the same payment on revenue takes a very different share of the rent from different fields.

Worked exampleOne royalty rate for three fields
Given (assumed data)
Oil price PP
US$50/bbl
Field A
technical cost cc = US$20/bbl, discounted production QdiscQ_\text{disc} = 10 million bbl
Field B
technical cost cc = US$34/bbl, discounted production QdiscQ_\text{disc} = 6 million bbl
Field C
technical cost cc = US$47/bbl, discounted production QdiscQ_\text{disc} = 4 million bbl
Payment to the state
royalty 10% of revenue; income tax is left out for simplicity
Solution
  1. The rent per discounted barrel P−cP - c is 30, 16 and 3 dollars. The rent of the fields (P−c) Qdisc(P - c)\,Q_\text{disc} is 300, 96 and 12 million dollars.
  2. The royalty is 0.1⋅50=50.1\cdot 50 = 5 dollars per barrel, that is 5 Qdisc5\,Q_\text{disc}: 50, 30 and 20 million dollars, or 16.7, 31.3 and 166.7% of the rent.
  3. The investor is left with the rent minus the royalty: 250, 66 and −8 million dollars. Field C is not worth developing at this rate.
  4. If the state took the same share of the rent from all of them, for example 40%, each investor would be left with 60% of the rent: 180.0, 57.6 and 7.2 million dollars, and all three fields would be developed.
Answer: A royalty of 10% takes 16.7% of the rent of the rich field A and more than the whole rent of the poor field C: C is not developed at this rate.

What it means. A single payment on revenue is too soft for the best fields and prohibitive for the worst, and then part of the resource that it would be profitable to produce stays in the ground. So owners look for forms of payment that follow the rent. These are tenders in which the rate reflects the value of a particular area, income and excess profit taxes, rates that depend on the volume of production or on the price, and special terms for complex and low-profitability fields. The income tax is left out of the example. With it, the investor's losses from the royalty are smaller for the profitable fields by the share of the tax, but field C remains loss-making. The data in this example are assumed for illustration.

Kazakhstan has examples of this approach. One is the rates of mineral extraction tax on oil, which in 2026 depend on the volume of annual production (from 5 to 18%), and from 2027 on the volume of production and the world price. Another is the special procedure for low-profitability fields: if the planned return on sales of a field for the year (its profit as a share of sales revenue) is zero or lower, the rate of the extraction tax for it is set by the Government (Petroleum fiscal systems and taxation). A similar tool exists in the USA: the federal government, as the owner of the outer shelf, can relieve the lessees of individual areas from part of the royalty if production there is expected to be unprofitable.

The risk of the terms reduces the rent

The rent depends on the rate at which the investor discounts the flow, and this rate includes a premium for risk (Choosing the discount rate). One of the risks is that the owner, who is also the legislator, will change the terms after the money has been invested. The less reliable the rules look, the higher the investor's rate, the smaller the rent, and the less the owner itself can take.

Worked exampleA premium for the risk of the terms
Given (assumed data)
Project
from the examples of the lesson; royalty 10%, income tax 20%
Investor's rate
10% when the terms are reliable; 15% with a premium of 5 percentage points for the risk that they will change (assumed)
Solution
  1. The rent at 15%: the NPV of the flow before payments to the state is 126.64 million dollars instead of 175.45 at 10%, which is 28% less.
  2. The investor's NPV at 15% is 64.38 million dollars, and the discounted production is 6.5588 million bbl.
  3. The limit royalty rate: 0.10+64.38/(0.8⋅50⋅6.5588)0.10 + 64.38/(0.8\cdot 50\cdot 6.5588) =0.10+64.38/262.35=0.10+0.2454= 0.10 + 64.38/262.35 = 0.10 + 0.2454, that is, 34.5% of revenue against 41.7% at a rate of 10%.
Answer: A premium of 5 points for the risk of the terms reduces the rent of the project from 175.45 to 126.64 million dollars, and the limit royalty rate from 41.7 to 34.5%.

What it means. Stable terms are not a concession to the investor but a way to enlarge the rent that the owner can share. The Subsoil Code names stability of subsoil use terms as one of the principles of the legislation (Article 4) and protects signed contracts from changes for the worse, although not in all fields. The size of the premium in the example is assumed. In practice it is estimated from the capital market and the experience of the industry. The data in this example are assumed for illustration.

    A subsoil user has produced oil under a contract for hydrocarbons in Kazakhstan. Who owns this oil?

    1. A.The state: the subsoil and everything extracted from it is the property of the people
    2. B.The national company in the field of hydrocarbons
    3. C.The subsoil user, unless the Subsoil Code provides otherwise
    4. D.The state until taxes are paid, and then the subsoil user
    Show the answer

    Correct answer: C. The subsoil user, unless the Subsoil Code provides otherwise

    Under Article 15 of the Code, the produced minerals belong to the subsoil user as property, unless the Code provides otherwise. The subsoil belongs to the people, on whose behalf the state acts. The state receives its share of the value of what is produced through payments, not through ownership of the barrels.

  2. 2

    A farmer in Kazakhstan owns a plot of land as private property. Oil has been discovered under the plot. What is true?

    1. A.The oil belongs to the farmer, but the farmer can produce it only under a licence
    2. B.The farmer can lease the rights to the oil to an oil company for a bonus and a royalty
    3. C.The subsoil under the plot does not belong to the farmer: the right to produce oil is given by a contract with the competent authority
    4. D.The oil belongs to the farmer as the owner of the land
    Show the answer

    Correct answer: C. The subsoil under the plot does not belong to the farmer: the right to produce oil is given by a contract with the competent authority

    The Constitution allows private ownership of land, but the subsoil belongs to the people, and the state exercises the right of ownership on their behalf. The first two options describe the American system of private rights to oil and gas. How a subsoil user uses the farmer's land is decided by land legislation and the Subsoil Code, but the oil under the plot does not belong to the farmer.

  3. 3

    In the example project of the lesson, at US$50/bbl and a rate of 10%, the rent is 175.45 million dollars. The state raises the royalty from 10% to 20%, and the income tax stays at 20%. How do the present value of the payments to the state and the investor's NPV change, and why does their sum not change?

    Show the answer

    Each point of royalty costs the investor 0.8⋅0.5⋅7.8987≈3.1590.8\cdot 0.5\cdot 7.8987 \approx 3.159 million dollars, and ten points cost about 31.59 million dollars. The investor's NPV falls from 100.13 to 68.54 million dollars, and the payments to the state grow from 75.32 to 106.91 million dollars. The sum stays 175.45 million dollars: in each year the flow before payments is equal to the sum of the payments to the state and the investor's flow, and in the model production and costs do not depend on the rate.

  4. 4

    Why is a royalty rate that takes the whole rent in the project of the examples at US$50/bbl (about 41.7%) dangerous for the state itself?

    Show the answer

    At this rate the investor is left with exactly the required return, 10%. If the price turns out to be US$40/bbl, the investor's NPV becomes negative (−37.1 million dollars), and the project will not start. The state will get no bonuses, no taxes and no orders for its economy. If the price is US$60/bbl, the investor will get 36.8 million dollars over and above the required return, which the owner had expected to take. A rate “on the edge” is right for only one scenario. This is why part of the payments is made to depend on the profitability of the project (Petroleum fiscal systems and taxation).

  5. 5

    Which changes of the legislation of Kazakhstan that make the position of a subsoil user worse apply, under the Subsoil Code, to contracts that have already been signed?

    1. A.Any changes, if the Government has approved them
    2. B.Only changes in the rules for holding auctions
    3. C.None: changes for the worse do not apply to signed contracts
    4. D.Changes in taxation, and also in national security, defence capability, environmental safety, public health, customs regulation and protection of competition
    Show the answer

    Correct answer: D. Changes in taxation, and also in national security, defence capability, environmental safety, public health, customs regulation and protection of competition

    Article 36 of the Code protects signed contracts from changes for the worse, but not in the fields listed. So the tax terms of most contracts change together with the Tax Code. A stable tax regime is kept for production sharing agreements signed before 1 January 2009 that passed the mandatory tax expertise, and for contracts approved by the President. For contracts on complex projects, some tax norms apply in the version at the date of signing.

  6. 6

    A company holds a 30% share in a contract for a field with geological reserves of 80 million t of oil (oil in place), confirmed by the state expert review. It has found a buyer for its share. What does the state priority right change for the deal?

    Show the answer

    An area with geological reserves of more than 50 million t of oil is strategic (Article 43 of the Code). Selling the share needs the permission of the competent authority, and the question of the priority right is considered together with the application. If the state decides to use it, the share will be bought by the national managing holding or the national company, at a price and on payment terms no worse than those stated in the application (Article 46). The seller will get its price, but the buyer may change. This is taken into account when valuing the cost of leaving the project.
