Schlumberger's MDT Forte qualified rugged system and the MDT Forte-HT high-temperature version promise to deliver robust downhole-fluid analysis, fluid sampling, and transient testing to meet the challenges of oilfield operations. The two new platforms have been redesigned and re-engineered to tolerate excessive vibration from low-frequency shaking during transit to high-impact shock and vibration downhole at extreme temperatures. The PressureXpress-HT service provides accurate formation-pressure measurements under extreme conditions. Rated at 450 degF and 20,000 psi for at least 14 hours, the service acquires pressure and fluid-mobility measurements in a fraction of the time required by multifunction formation-tester tools.
