Borehole Logging Geophysics and Inspection

Mining Services

Borehole geophysical logging methods have been demonstrated in a wide variety of geologic environments often found in an exploration setting and have proven useful in geologic interpretations and in-situ mineral evaluation.

Ore body delineation

  • ELOG Combination Gamma, SP, SPR, 16-64-inch normal resistivity tool
