Description:
|
In conjunction with NEC and HAS, the Litho-density logs and the Micro-spherically Focused logs can be provided. The LDS uses a sonde-mounted gamma ray source (1.5Ci, Cs137) and two detectors to measure the bulk density and the effective photoelectric effect (Pe) of the formation. A caliper is also recorded. The tool uses two detectors to compensate the measurement result for the effects of mud cake and hole rugosity.
