Fast, Accurate Pressure and Mobility Measurements
PressureXpress reservoir pressure while logging service reduces the pressure testing process to less than a minute in most cases. You’ll get real-time data measured in a fraction of the acquisition time required by multifunction formation testers.
Unlike conventional formation pressure test tools, PressureXpress service delivers pressure and fluid mobility measurements during the first logging run.
Get the Right Data
The PressureXpress tool quickly generates a survey of reservoir pressure for connectivity analysis, a pressure gradient for fluid density and fluid contact information, and fluid mobility data 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.
Minimize Sticking
The tool’s OD and profile are designed to greatly reduce the risk of sticking. The eccentered tool shape, combined with a slight overbalance in setting force by the backup anchoring pistons, ensures an integral 1/2-in standoff from the formation during pretesting.
The smooth tool profile minimizes mudcake scraping when the PressureXpress tool is run in the hole. There are no external tool angles over 20°.
