Downhole Reservoir Testing

Reliable, repeatable drillstem test data for informed characterization decisions

The information you need to understand the reservoir

Since performing the first drillstem test (DST) in 1926, we’ve performed downhole tests that help customers economically achieve their test objectives. When your goal is to unambiguously determine reservoir pressure, permeability, skin, and productivity, our downhole technologies reliably deliver the right answers.

Even in hostile well conditions, we’ll get you accurate downhole pressure measurements. Flexible tool designs deliver reservoir information from multiple zones on the same test, saving rig time and powering rapid updates for your reservoir models.
