Live downhole reservoir testing
Test your well with tools, expertise, and global capabilities, all in harmony.
Downhole reservoir testing system
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.
The Quartet system is short but powerful, providing numerous advantages over conventional testing strings:
The CERTIS system combines many features of a conventional retrievable packer with those of a permanent production packer, including a built-in floating seal assembly that eliminates the need for drill collars and slip joints. No string manipulation is required for setting—just apply annulus pressure to activate the hydraulic setting mechanism. At the end of the test, a straight pull releases the packer and then reopens the bypass to eliminate swabbing when coming out of the well.Learn More
The IRDV valve combines a tester valve and a circulating valve that can be cycled independently or in sequence for efficient, nitrogen-free multicycle operations. Both valves can be operated with a single command that is immune to downhole pressure and temperature and easily applied with low-intensity annular pulses.Learn more
With 100% ceramic-based electronics and proprietary long-life batteries, Signature quartz gauges acquire high-quality pressure data for the entire test duration.Learn More
SCAR sampling captures independent and redundant representative fluid samples from deep within the reservoir. Collection directly in the flow stream eliminates contamination caused by dead volumes.Learn More
