Schlumberger introduces new downhole reservoir testing system

Offshore staff

FLORENCE, Italy — Schlumberger has announced the release of a new high-performance downhole reservoir testing system, designed to allow 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 system’s single-trip efficiency, the operator saved four days of rig time while safely achieving its test objectives, Schlumberger said.

The downhole assembly is one-fourth the length of conventional configurations. The company says 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 system, named Quartet, consists of four technologies engineered specifically for reservoir testing: high-integrity reservoir test isolation system, intelligent remote dual valve, crystal quartz gauge, and inline independent reservoir fluid sampling.
