This would apply correction for apparent high strength in UCS and CCS, which are key inputs in geomechanical models. Reservoir Characterization rotary sidewall...

... in the reservoirs. To improve the geomechanical models, a series of field tests were carried out to estimate minimum u stress and fracture propagation pressure in both reservoir and cap rock. The tests results allowed a change in the criterion for definition of the maximum injection pressure in injector wells...
