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.
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.
