Single-trip reservoir testing that combines four leading technologies

The Quartet downhole reservoir testing system lets you directly interact with four integrated tools to isolate, control, measure, and sample in one run using a single test solution. The system enables you to obtain the most accurate characterization of your reservoir and achieve safer and more efficient drillstem tests (DST) that are in tune with your test objectives.

Downhole string technology—simplified

The Quartet system is short but powerful, providing numerous advantages over conventional testing strings:

• Lower operating pressure and less nitrogen increase operational safety.
• Shorter string combines four tools while eliminating drill collars and slip joints and requiring fewer seals and connections to provide more efficient handling for more cost-effective downhole testing.
