Formation Evaluation

Reduce reservoir uncertainty

Our experienced technicians and industry leading technologies help you collect, interpret, and apply formation evaluation data to locate the optimal formation target. We leverage our comprehensive wellsite services―including onsite labs, logging-while-drilling, wireline, and surface logging systems―with laboratory-based fluid and core services to transform downhole uncertainty into informed well-construction and production decisions.

Logging While Drilling

Characterize the subsurface environment while drilling

Working in standard to extreme drilling environments, our technologies deliver real-time petrophysical, geosteering, imaging, geomechanical, and geophysical data that enhance reservoir understanding and enable on-the-fly drilling adjustments.
