Reservoir Evaluation

Bringing you closer to the reservoir

Reservoir Evaluation

We offer a full in-house scope of service for oil and gas operators’ reservoir formation evaluation.

Our specialist technologies, including our cutting-edge pulsed neutron Reservoir Analysis System (RAS) which uses Sigma and Carbon-Oxygen, help identify and exploit bypassed reserves and maximise hydrocarbon recovery. 

Each reservoir is unique. The clarity of our insight allows you to understand the reservoir’s conditions and challenges, and quantify hydrocarbons in the rock. You can trust us to deliver highly accurate measurements that ultimately give you an improved understanding of your well production, and help you better manage your reservoirs.

We bring you closer to the reservoir by:
