Geomechanical-Reservoir
Simulation Services
 Do you have a suspicion that perhaps more than just your reservoir
fluids are moving when you produce or inject in your reservoir? You're probably right.
The industry is increasingly recognizing the role that geomechanics
plays in hydrocarbon production. From sinking platforms in the North Sea
that cost billions of dollars to fix to injection-induced seismicity we
now have a better understanding of the processes that control reservoir
deformation, and in some cases, caprock and casing failures.
Weatherford Geomechanics Services provides consulting and research services in geomechanical-reservoir simulation using FLAC - a
commercial finite-difference code developed by the Ithasca Consulting Group for modeling stress, thermal and fluid
flow problems in a wide variety of rock types and reservoir settings.
Results from FLAC can be used with other multi-phase flow
simulators for more robust coupled reservoir and geomechanical analyses.
We also use a sister code called UDEC for modeling
fractured reservoirs. Here are some of the problems we can address with
these powerful simulation tools:
- Prediction of permeability enhancement during cyclic
steam stimulation (CSS) or steam assisted gravity drainage
(SAGD)
- Cold flow production with sand (CHOPS) in heavy oil
reservoirs
Waterflooding under fracturing conditions
- Reservoir and caprock deformations in CO2 EOR and GHG
Sequestration
- Fault reactivation and fracture reopening risks
- Caprock integrity analysis for waste disposal operations
- Reservoir compaction and subsidence predictions
- Casing failures in deformable reservoirs
- Wellbore instability and sand production risks
- Reservoir stress changes in gas storage reservoirs
- Induced seismicity risk assessments
- Feasibility studies for microseismic monitoring
