HPHT Reserves Evaluation

Complete suite of HPHT logging tools

Schlumberger brings a wealth of experience to HPHT wireline logging. Tools are available for a complete suite of measurements including resistivity, sonic, density, neutron porosity, gamma ray, and borehole temperature. Compatible with these services, the PressureXpress-HT high-temperature reservoir pressure service can perform extended reservoir pressure and mobility surveys for an industry-leading holding time of 14 h at 232 degC [450 degF]. The MDT Forte-HT rugged high-temperature modular formation dynamics tester delivers robust downhole fluid analysis (DFA), fluid sampling, and transient testing.

Improved wireline conveyance in deep, hot wells

Use of high-tension cable and a capstan reduces the risk of tool sticking in deep HPHT wells. Capstans also reduce cable tension before respooling, minimizing cable damage and shorts between conductors. Power loss is a concern for longer cables; our HPHT quad cable can supply three times as much power as a standard cable.

Accurate and reliable HPHT well testing

Our well test equipment is rated 260 degC [500 degF] and 207 MPa [30,000 psi]. Signature quartz gauges feature 100% ceramic multichip module placed on a single ceramic substrate for dramatically improved reliability. These highly-accurate gauges enable longer well tests and consequently, exploration beyond the near-wellbore area. High-pressure SenTREE subsea test trees are engineered for integration with the subsea BOP stack and any completion, well test, or Christmas tree system.
