Its reservoir optimization services and technologies are interrelated and are organized into three complementary segments: Reservoir Description, which encompasses the characterization of petroleum reservoir rock, fluid and gas samples; Production Enhancement, which includes products and services relating to reservoir well completions, perforations, stimulations and production, and Reservoir Management, which combines and integrates information from reservoir description and production enhancement services.
