Depth
The essentials, key relationships and typical mistakes, to refresh a topic fast.
The lesson step by step: from the concept to the mechanism and its use, with worked examples and checks.
For advanced readers: derivations, method comparisons, hard cases and model limits.
Disciplines
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.
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.
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.
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.
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.
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.
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.
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.
