We support subsurface projects across the entire energy industry, from traditional oil and gas to geothermal and geologic storage.

Optimized Reservoir Development

3D Coupled Geomechanics

We help you to build models that capture regional and local stress magnitudes and orientations as they are affected by the presence of faults and salt domes. Our 3D models can be used to address topics like cap rock integrity, fault stability, compaction, subsidence, induced seismicity and more. 

Reservoir Compaction and Subsidence

We help you assess whether during production your reservoir will compact as a result of the change in pore pressure. Our models can also assess whether the compaction at the reservoir would propagate to the surface resulting in subsidence. Conversely, we can assess whether injection can result in reservoir deformation and ground level heave. These deformations at the reservoir or surface level can put at risk below and above surface facilities.

Safe Operational Drawdown

We help design drawdown programs to mitigate risks due mechanical skin and well integrity by modeling stress concentrations near the wellbore that arise from continuous reservoir production. 

Induced Seismicity

We can assess the risk of induced seismicity associated to fluid injection in the subsurface by building 3D geomechanical models that assess the state of stress near faults and the likelihood of shear failure that could lead to earthquakes.

Stress-Sensitive Fractured Reservoirs

We help you understand the impact of changing stresses due to depletion on the overall permeability of the natural fracture network by modeling the change in normal stress acting on each fracture and the corresponding change in mechanical aperture. Under injection operations, we help you predict which fracture orientations are more prone to shear failure and so to increase permeability.
