PressureXpress-HT High-Temperature Reservoir Pressure Service

Fast, accurate pressure and mobility measurements in high-temperature environments

New PressureXpress-HT service extends the efficiency and accuracy of PressureXpress reservoir pressure while logging service to high-temperature environments. Specifically engineered for pressure and mobility testing—whereas conventional multifunction formation tester tools also collect fluid samples—these tools significantly reduce the time and risk involved with multifunction testing operations. Highly accurate reservoir pressure and mobility measurements are typically made in less than a minute, because the flasked tool design and superior thermal stability of the quartz gauge eliminate the need for gauge temperature stabilization.

14-h extended single-trip surveys at 450 degF

With a design optimized for heat management, PressureXpress-HT service can perform extended surveys for an industry leading holding time of 14 h at 450 degF [232 degC]. And you can get pressure measurements on the first logging run, thanks to the compatibility of PressureXpress-HT service with most openhole services.

Dynamically controlled pressure pretests

The versatile, enhanced pretest system incorporated in PressureXpress-HT service gives you precise, real-time control of volume and drawdown rates across a wide mobility range. Pressure limits can be set as necessary. With a drawdown pressure differential of up to 8,000 psi and the capability for ultrasmall pretest volumes and minimal flowline storage, PressureXpress-HT servicel makes pressure testing possible in formations where conventional hydraulic technology cannot operate.
