Vista Clara has successfully completed field testing of Javelin Micro. With a 1.75 inch (44mm) diameter, Javelin Micro is the world’s first wireline NMR logging tool capable of logging 2 inch ID PVC boreholes.
Field testing was conducted at the Moab Uranium Mill Tailings Remedial Action (UMTRA) site in Moab, UT, in conjunction with a project that used the Javelin Slim 2.38 inch logging tool.
Below is a comparison of data from Javelin Micro and Javelin Slim, which confirms efficacy of the new smaller diameter tool.

NMR system
- Runs from Javelin wireline NMR surface unit, and 4-conductor wireline with GO-4 or Century logging head.
- Supported by standard Javelin Pro Software for in-field and in-lab data analysis
- Comes standard with 2 frequency detection, with 2 simultaneous diameters of investigation of 9 inches and 10 inches. This is important for logging 2” PVC monitoring wells that are often drilled with 7 or 8 inch drilling diameters.
- Tuning frequencies can be increased for smaller diameters of investigation and higher SNR/faster logging speed if desired.
