The Javelin and Dart suite of borehole tools is engineered with a priority on accuracy and flexibility, providing valuable data in almost any bore size with the power to see beyond the drilling disturbance. At any depth or borehole size, an optimized NMR logging solution is available for your project.

Vista Clara’s NMR logging tools are available in three system configurations, to meet the budgets and operational requirements of any groundwater, environmental or mining project:

  • Dart: battery-powered NMR logging tool for highly mobility, narrow bores, or shallow targets.
  • Javelin®: Highly flexible, lightweight logging platform for environmental and groundwater logging to 400m.
  • Javelin® Wireline: For logging to depths of up to 1000m using industry-standard 3/16″ 4-conductor wireline and truck mounted winches.

Javelin and Dart systems deliver accurate and efficient hydrogeologic characterization in a high-resolution log. Operating over a wide range of borehole sizes, these tools allow determination of porosity, bound/mobile water content, and hydraulic conductivity. Vista Clara’s NMR logging tools bring cost savings and informed decision making to markets such as groundwater resources, environmental remediation, geotechnical engineering, and mining.
