Telemetry Gamma Ray and CCL Tool
Provides integrated telemetry and correlation services
Applications
- Facilitates the combination of HD compatible services into a single logging string
Features and Benefits
- Fast up-hole telemetry
- Integrated gamma ray for correlation to formation
- Integrated casing collar locator (CCL) for correlation to wellbore tubulars
Tool Description
The Weatherford telemetry gamma ray and CCL is a combined gamma ray and CCL tool with a telemetry control unit which provides a passive measurement of gamma radiation by means of a sodium iodine scintillation detector and identifies changes of metal thickness by means of a collar locator.
The telemetry control unit is the communications control center for the logging system. The tool controls the collection of data from the tools below and packages it for the transmission to the surface system.
