Video What Is Dynamic Reservoir Evaluation?
How both deep transient testing and drillstem testing are key to improving reservoir formation testing
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.
Formation Testing: The Early Days
Discover how, in 1926 near El Dorado, Arkansas, Edgar and Mordica Johnston performed the first commercial drillstem test (DST).
