Quartet High-Performance Downhole Reservoir Testing System

All Together Better Reservoir Testing

The Quartet high-performance downhole reservoir testing system is an advanced test solution that delivers the highest quality pressure measurements and the most representative fluid samples with maximum safety and efficiency, for altogether better reservoir testing.

In addition to the elimination of drill collars and slip joints, the Quartet system offers multiple advantages over conventional string configurations, including

• 35% lower operating pressure
• 90% less nitrogen
• 75% shorter string design
• 100% premium connections
• 50% fewer seals
• 60% fewer connections.

The Quartet system combines four leading downhole testing technologies into one advanced string design, providing accurate, deep-reading, high-resolution pressure measurements and contaminant-free, reservoir-representative fluid samples—all in a single run.

Adding to the system’s single-trip efficiency is the ability to run large perforating guns below the packer, set the packer, perforate, test, and retrieve the test string in one run. The Quartet system also provides the option to place a below-packer circulating valve (BPCV) on the test string for a more efficient well kill, especially important when testing gas wells.

Control with IRDV 

The IRDV intelligent remote dual valve combines a tester valve and a circulating valve that can be cycled independently or in sequence.

Sample with SCAR 

SCAR inline independent reservoir fluid sampling delivers representative fluid samples from deep within the reservoir; samples are collected directly in the flow stream to eliminate contamination caused by dead volumes.

Measure with CQG 

The field-proven CQG crystal quartz gauge leads the market in high-quality pressure measurements; designed from proprietary sensor technology, the gauge dramatically reduces thermal effects and provides the most accurate pressure measurements available.

Isolate with CERTIS 

The CERTIS high-integrity reservoir test isolation 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.
