Downhole Testing

Since performing the first drillstem test (DST) in 1926, we've designed downhole testing jobs to achieve test objectives economically. Whether your goal is to determine reservoir pressure, permeability, skin, or productivity, our downhole technology delivers the right answers. Accurate downhole pressure measurements, even under very hostile conditions, increase your confidence in reservoir characterization. Flexibility in downhole tool design gives you reservoir information from multiple zones on the same test, saving rig time and allowing you to update your reservoir model sooner.

Quartet Downhole Reservoir Testing System

Enable the Quartet system with wireless telemetry to monitor and manage wellbore events as they happen, validate pressure data while you test, and ensure that you've met your test objectives before ending your test.
