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

Safe Drilling and Completions

Pore Pressure and Fracture Gradient

We provide pre-drill pore pressure and fracture gradient estimates to ensure safe drilling by preventing well kicks (inflows) and severe mud losses.

Wellbore Stability

We help you develop an optimized casing and mud program to prevent wellbore instability and to reduce NPT by integrating in situ stresses and rock mechanical properties into a geomechanical model that predicts wellbore failure.

Mud Salinity Optimization

We help you improve wellbore stability in narrow drilling windows by designing a mud salinity program that uses osmosis as mean to reduced borehole collapse pressure. 

Fault Stability

We help you avoid severe mud losses when drilling across faults by modeling the maximum allowable ECD before there is fault slippage and subsequent loss of drilling fluids.

Sand Production Prediction

We can help optimize your completions to eliminate the risk of sand production by establishing the maximum allowable drawdowns and optimal perforation orientation.  

Hydraulic Fracturing

We can help you design and optimize your hydraulic fractures to maximize the stimulated rock volume by constructing detailed stress profiles and taking into account the interaction between hydraulic and natural fractures.
