Depth

1Brief

The essentials, key relationships and typical mistakes, to refresh a topic fast.

2Core

The lesson step by step: from the concept to the mechanism and its use, with worked examples and checks.

3In depth

For advanced readers: derivations, method comparisons, hard cases and model limits.

Disciplines

01

Petroleum geoscience

How the Earth is built, where sedimentary rocks, source rocks, reservoirs and seals come from, how they are found by seismic surveys, correlated between wells and mapped, and how hydrocarbon volumes are estimated.

39 / 39 topics
02

Formation evaluation from well logs

How to determine lithology, porosity, saturation and productivity of formations from open-hole logs: the physics of the tools, rock and fluid properties, the interpretation workflow and charts.

28 / 28 topics
03

Reservoir engineering

Pressure and temperature in the reservoir, the composition and phase behaviour of fluids, PVT properties, rock properties, flow in porous media, reservoir drive mechanisms, material balance, aquifer influx and the displacement of oil by water.

48 / 48 topics
04

Well testing and pressure transient analysis

What can be learned about a reservoir from the change of pressure in a well: radial flow, analysis of pressure drawdown and build-up, wellbore storage, type curves, boundaries, a bounded drainage area and distributed pressure measurements.

33 / 33 topics
05

Reservoir simulation

How numerical reservoir models are built and used: problem definition, the grid and well models, the flow equations, numerical methods, permeability upscaling and petrophysical input data.

19 / 19 topics
06

Drilling engineering

The drilling rig, the drill string and bits, formation pressures and well control, casing and cementing, drilling fluids and hydraulics, directional drilling and telemetry, subsea drilling.

35 / 35 topics
07

Oil and gas production

Well completion, inflow from the reservoir and tubing performance, artificial lift and gas lift, perforating, formation damage and its removal — acid treatments and hydraulic fracturing, sand production, field facilities and processing of production.

40 / 40 topics
08

Oil and gas project economics

The industry and the market, methods of project evaluation, the time value of money, performance measures, fiscal and contractual regimes, uncertainty and risk, risk management.
