Mini Logging Tool (MLT) 300

Mini Logging Tool (MLT) 300

All the benefits; one small modular package.

The Mini Logging Tool (MLT) is a compact version of a production logging tool. It is designed to be a modular tool, with three main modules being the platinum Resistant Temperature Detector (RTD) module, the Casing Collar Locator (CCL) module and the Pressure/Flow module.

The Dual Platinum Resistant Temperature Detector (RTD) module provides a fast, high-resolution temperature profile along the wellbore.

The electromagnetic CCL measures depth by measuring the change in electromagnetic field that occurs at each casing, or tubing collar.

The Pressure/Flow module has a universal external housing. Different gauges are inserted into the external housing, depending on what pressure range the tool will be encountering.

Why the MLT 300?

  • Collect data where other tools can’t fit
  • Use any combination of modules, thanks to a modular design
  • Redeploy while downloading data with a replaceable memory module
  • Detect even tiny temperature changes with sensitive, dual resistant detectors
  • Create an accurate and economical tool for multiple applications with single external Pressure & Flow housing and multiple calibrated modules

Applications

  • Detecting casing leaks
  • Surveying gradients
  • Production optimization
  • Evaluating reservoirs
  • Well testing
  • Slickline operations
  • Production logging
  • Temperature logging
