Magnetic Multishot Survey Tool

Definitive openhole survey information.

Our Magnetic Multishot Tool (MMT) provides definitive openhole survey information and can be run at any time during the drilling process or before making a bit trip to make directional course corrections. The MMT is also suitable for oriented coring.


The MMT provides a comprehensive multishot service package offering numerous advantages, including:

  • High reliability through the use of either industry-standard quartz or rugged silicon accelerometers
  • Small size for slimhole and short-radius applications: 1a-in. (34.9-mm) or 1w-in. (44.45-mm) running gear
  • Option of low- (120 °C), standard (150 °C), or high-temperature (>150 °C) tool configurations (<5.5 hours at well temperatures of 315 °C) inside a thermal flask
  • Standard interface providing multisensor options that can be used for verification and/or sensor redundancy purposes
  • High-capacity data storage (5,000 shots), providing increased data resolution and extended downhole time
  • Both multishot and singleshot service options in one tool
  • Comprehensive 32-bit reporting software
  • Custom-designed hydro-mechanical decelerator available
  • Double battery stack allowing for up to 60 hours (alkaline) or 90 hours (lithium) operation (based on one survey shot per minute)
