Advanced Oil Detection Technology

Gamma Ray CCL Temp

The Gamma Ray / Collar Locator / Temperature Tool (GCT) integrates three essential downhole measurements in a single tool. It provides gamma ray detection for formation evaluation, collar locator signals for depth correlation, and accurate temperature logging with a fast-response platinum RTD sensor. Designed for real-time or memory operations with the Fast Hybrid Telemetry Tool (FHT), the GCT ensures reliable data acquisition in multiple wellbore conditions.
