PressureXpress Reservoir Pressure While Logging Service

Compatible with most openhole services, including the Platform Express integrated wireline logging tool and its foundation measurements for formation evaluation, PressureXpress reservoir pressure while logging service specifically conducts pressure and mobility testing. On the first logging run, a reservoir pressure survey can be quickly generated for connectivity analysis, along with the pressure gradient for fluid density and fluid contact information and fluid mobility determination to aid in sampling-point selection.

These data are the basis for accurate pressure profiles and mobility measurements that you can integrate with petrophysical, seismic, and conventional log data for a more complete reservoir picture. Our expert, multidisciplinary geoscientists and engineers work with you as needed to achieve an integrated interpretation, employing advanced workflows and software such as the Techlog wellbore software platform to maximize the value of your logging data and achieve the fullest possible understanding.
