Javelin Wireline acquires precise magnetic resonance logging data to depths of 4000 ft using industry standard wireline cable.
Javelin Wireline Applications Include:
- Groundwater Resource Evaluation
- Aquifer Storage and Recovery
- Saline Aquifer Characterization
- Mine Water Management
- Environmental Impact Assessment
- In-situ Leach Mining
Sample data above: A Javelin NMR log yields a continuous and high-resolution measurement of primary hydrogeologic properties, including porosity, bound/mobile water content, and permeability, and operates in PVC, fiberglass, or open holes.
The unique design features of Javelin Wireline enable performance over a wide range of borehole environments and drilling conditions.
View Beyond Drilling Disturbance
Drilling disturbs the formation around the borehole. Javelin provides deep view sensitivity, detecting the native formation in a sensitive shell located past the disturbed zone. This large diameter of investigation allows Javelin to operate in larger hole diameters, avoiding influence from washout and mud-invasion.
Javelin Wireline simultaneously acquires data at multiple frequencies to obtain sensitivity at up four discrete diameters of investigation. Shells can be combined in post-processing to improve data quality or can be analyzed independently to assess radial variation or drilling artifacts.
