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.
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.

We provide actionable wireline data and flawless service execution from early field exploration to mature-field production. Our proprietary technologies assess productivity, diagnose downhole issues, and inform infill drilling programs.
