ACTive GR CT Real-Time Gamma Ray Logging Tool | Schlumberger


CT real-time gamma ray logging tool

Improve performance and depth correlation

Gamma ray (GR) measurements are available with the ACTive real-time downhole CT services, which provide downhole measurements enabled by fiber-optic telemetry. The ACTive GR CT real-time gamma ray logging tool detects naturally occurring gamma rays in the formations adjacent to the wellbore, while maintaining pump-through capability for CT intervention. The service provides you with an industry-standard measurement for depth correlation while maintaining pumpthrough capability.

Enhance operational efficiency

The GR tool enhances other ACTive services when run in combination. For instance, ACTive Perf CT real-time perforating service is augmented by accurate depth control and perforating the target zone in a single run while monitoring the hydrostatic balance with the integral pressure sensor. ACTive Matrix CT real-time stimulation and conformance service improves fluid placement by combining distributed temperature measurements with monitoring of radioactive tracers in stimulation fluids.
