Schlumberger Introduces New Downhole Reservoir Testing System
Quartet System Delivers High-Resolution Pressure Measurements and Representative Fluid Samples for Safer and More Efficient Reservoir Testing
Schlumberger announced today at the 2010 SPE Annual Technology Conference and Exhibition the release of the Quartet* high-performance downhole reservoir testing system. This complete downhole testing system allows operators to isolate, control, measure and sample all in a single run.
″Now operators can test more safely and efficiently for an altogether better reservoir test,″ said Devan Raj, marketing and technology manager, Schlumberger Testing Services. ″The deep-reading, high-resolution pressure measurements and representative reservoir fluid samples help operators prove reservoir potential and reach a better basis for their decisions.″
During exploration in the Gulf of Venezuela, an operator needed to perform a series of downhole tests on its high-rate gas wells to determine reservoir properties. With the Quartet system’s single-trip efficiency, the operator saved four days of rig time while safely achieving its test objectives.
The Quartet downhole assembly is one-fourth the length of conventional configurations. The system offers a range of advantages, including 35% lower tool operating pressure, 90% less nitrogen, 50% fewer seals and 60% fewer connections. In addition, drill collars and slips joints are eliminated from the downhole string.
The Quartet system consists of four technologies engineered specifically for reservoir testing: CERTIS* high-integrity reservoir test isolation system, IRDV intelligent remote dual valve, CQG* crystal quartz gauge and SCAR* inline independent reservoir fluid sampling.
