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.
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.
Get reservoir-representative fluid samples and high-resolution pressure measurements with multicycle flexibility in a single run and at ultrahigh temperatures.
Reliably perform ultrahigh-temperature, ultrahigh-pressure reservoir tests with Schlumberger simple and rugged string designs rated to handle extreme downhole conditions.
Assemble an optimal downhole test string with a wide variety of tools and equipment designed to fit your test objectives in any operating environment.
