PressureXpress-HT High-Temperature Reservoir Pressure Service

Compatible with most openhole services, including the triple- and quad-combo platforms that provide the foundation measurements for formation evaluation, PressureXpress-HT high-temperature reservoir pressure service specifically conducts pressure and mobility testing in high-temperature environments, including low permeability. 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 for the fullest possible understanding of challenging reservoir environments.
