Universal Gamma Ray-K Tool

Contact

Provides correlation between openhole logs and subsequent cased-hole runs

Applications

  • Can operate in any borehole environment for effective correlation
  • Enables deployment in thru-tubing completions with IDs as narrow as 1-7/8 in.
  • Logs in combination with production-logging, pulsed neutron, slim Sector Bond, and other intertool-bus-compatible tools with a diameter of 1-11/16 in.

Features and Benefits

  • The small diameter enables the universal gamma ray-K (UGR-K) tool to log through restrictions and to run in completions as narrow as 1-7/8 in., making it very versatile.
  • Calibration for the API standard means the tool delivers measurements that are ideal for determining shale volumes and for making matrix corrections in pulsedneutron logging.
  • The temperature-compensation algorithm makes the tool stable over the entire operating range for accurate gamma-ray measurement.

Tool Description

The Weatherford universal gamma ray-K (UGR-K) tool measures natural radioactivity in the borehole at varying depths. It is primarily used in cased-hole environments to evaluate lithology and correlate the depth between openhole logs and subsequent cased-hole runs. With a diameter of 1-11/16 in., the tool can be deployed in thru-tubing completions with IDs as narrow as 1-7/8 in.

The UGR-K tool can operate in any borehole environment, which makes it an effective correlation device. It is typically run in combination with other logging tools, such as production-logging, pulsed neutron, slim Sector Bond , and any other tool of the same diameter (1-11/16 in.) that is compatible with intertoolbus (ITB) communication.
