Geomechanics for Petroleum Engineers
This training covers geomechanics for petroleum engineering applications. It works through stress and strength essentials, pore pressure and effective stress, wellbore stability and mud weight design, sand production prediction and control, hydraulic fracture design inputs, compaction and compressibility in reservoir engineering, injection and fault stability, well integrity under stress change and the inclusion of geomechanics in engineering decisions.
Description
Geomechanics affects petroleum engineering decisions continuously and is often treated as a specialist subject consulted after problems occur. Mud weight windows, casing seats, completion type, sand control selection, fracture design, injection pressure limits, compressibility in material balance and well integrity in depleting fields are all engineering decisions with a geomechanical basis. This training gives petroleum engineers the understanding required to make those decisions and to work effectively with geomechanics specialists.
The course is structured by application. Stress and strength essentials are established first at the level required, covering the stress tensor, principal stresses, the in-situ stress field, rock strength and failure criteria, without unnecessary theory. Pore pressure and effective stress follow, covering the central principle and the sources of pressure data. Wellbore stability and mud weight design are then developed as the first major application, covering the stability calculation, the mud weight window and trajectory effects. Sand production prediction and control follow, covering the mechanisms and the critical drawdown calculation. Hydraulic fracture design inputs are then addressed, covering the stress and property data the design requires. Compaction and compressibility in reservoir engineering follow, covering material balance implications and compaction drive. Injection and fault stability are then developed. Well integrity follows. The training closes with geomechanics in engineering workflows.
Pore volume compressibility in a weak reservoir is not a constant and material balance assumes it is. In competent sandstone the pore compressibility is small and roughly constant, and treating it as a single number is adequate. In chalk, unconsolidated sand and other weak rock, compressibility increases sharply once the pore collapse pressure is exceeded, so the compressibility during late depletion may be several times its initial value. A material balance using the initial value will underestimate the compaction drive and therefore misattribute the pressure support, with consequences for the aquifer estimate and the recovery forecast.
Sand production has a calculable onset condition. Sand is produced when the drawdown generates stresses at the perforation or open hole face that exceed the rock strength, and the critical drawdown can be estimated from the stress state, the strength and the completion geometry. The calculation gives an operating limit, shows how that limit falls as the reservoir depletes, and allows the choice between sand control hardware and drawdown management to be made quantitatively rather than by default. It also shows when a well that has produced sand-free for years will start to fail.
The fracture gradient falls as the reservoir depletes and this changes drilling and injection limits. Depletion reduces the horizontal stresses, which reduces the pressure required to open a fracture. For drilling, this means a mud weight that was safe in the virgin reservoir may cause losses in the depleted one, and infill wells in mature fields frequently require a narrower window than the original wells. For injection, it means the maximum injection pressure is lower than the original fracture gradient would suggest, which has to be respected if containment matters.
Finally, injection pressure limits are set by fault stability as well as by fracture pressure. Raising pore pressure reduces the effective normal stress on nearby faults and moves them towards failure. The pressure at which a critically oriented fault slips may be lower than the formation fracture pressure, in which case the operating limit is set by the fault rather than by the rock. For disposal wells, for pressure maintenance and for any storage project, the fault stability calculation is the one that determines the safe injection pressure.
By the end of this training, participants will be able to:
- Apply stress, strength and effective stress concepts to engineering problems
- Interpret the available stress and pore pressure data
- Calculate mud weight windows and assess wellbore stability
- Assess trajectory effects on stability and casing seat selection
- Predict sand production onset and critical drawdown
- Select between sand control and drawdown management on a technical basis
- Specify the geomechanical inputs required for fracture design
- Apply stress dependent compressibility in reservoir engineering
- Set injection pressure limits from fracture and fault stability
- Assess well integrity risk under depletion and injection
The training works through engineering calculations on field data. Participants calculate mud weight windows and compare against drilling records, compute critical drawdown for sand production and compare against well histories, and derive injection pressure limits from both fracture and fault stability criteria. Material balance calculations are run with constant and stress dependent compressibility to show the difference.
