Live downhole reservoir testing
Test your well with tools, expertise, and global capabilities, all in harmony.
Quartet-HT
High-temperature downhole reservoir testing system
Single-trip reservoir testing up to 410 degF that combines four leading technologies
The Quartet-HT high-temperature downhole reservoir testing system brings new reliability and efficiencies to HT downhole testing. The integration of 100% quartz measurement sensors, all-ceramic multichip module electronics, and multicycle operational flexibility enables you to accurately characterize your reservoir in a single trip.
Additional efficiencies for HT operations are delivered by
- no drill collars or slip joints
- fewer seals and connections
- shorter string design
- less nitrogen
- lower operating pressure
- premium connections.
Combining four leading downhole tools for reservoir-representative samples at ultrahigh temperatures
CERTIS high-integrity reservoir test isolation system
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.

IRDV intelligent remote dual valve
The IRDV dual 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.
