Downhole Reservoir Testing

Reliable, repeatable drillstem test data for informed characterization decisions

Since performing the first drillstem test (DST) in 1926, we've performed downhole tests that help customers economically achieve their test objectives. Whether the goal is determining reservoir pressure, permeability, skin, or productivity, our downhole technologies deliver the right answers.

Accurate downhole pressure measurements, even under hostile conditions, increase your confidence in reservoir characterization. Flexibility in downhole tool design delivers reservoir information from multiple zones on the same test, saving rig time and allowing rapid updates to reservoir models.

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.
