Geophysical Logging Services



MM&A maintains fully digital, state-of- the-art equipment for specialized environmental, geotechnical, hydrogeological and coalbed methane applications. Logs can be generated in specific suites to meet your specific needs. Our leet of fully equipped geological logging units provide services including:


  • Acoustic televiewers

  • Borehole deviation

  • Borehole video cameras

  • Calipers

  • Electromagnetic (EM) flow meters

  • Fluid conductivity

  • Fluid temperature

  • Gamma-gamma density (high resolution or compensated)

  • Induction

  • Natural gamma ray

  • Neutron Various

  • Full waveform sonic tools for cement bond logs (CBL)

  • Fluid sampler

  • Various resistivity log


Our personnel help you determine the logging suites best suited to your specific application. We generate all suites in fully digital form, and send data to a central processing unit (CPU) located in a logging vehicle and to a disk for storage. This allows for re-plotting at a later date or transcribing to an ASCII, CSF, or AutoCAD ® drawing file (.DWG) format. Some of the specific applications our geophysical logging capabilities can be used for include stratigraphic investigations and fluid movement investigations. MM&A has assisted its international clients in acquiring the requisite equipment for remote site geophysical logging purposes including training the international staff in operating as well as maintaining the equipment.
