Borehole Magnetic Resonance (BMR) Tool
These tools measure the amount of water present in the pore space using permanent magnets and antenna, similar to an MRi machine in a hospital. The lithology independent techniques results in water (moisture) content above the water table and total porosity and pore size distribution below the water table.
BMR can provide secondary measurements such as specific yield (amount of moveable water) and specific retention (amount of bound water) as well as calculate estimates for hydraulic conductivity with additional information. The tool can measure through PVC, fiberglass or open hole conditions in dry or water filled boreholes and can be used in a range of sectors from hydrogeology to mining.
Features and benefits
Lithology independent measurement of water content/total porosity and pore size distribution
Lithology dependent measurements such as moveable and bound porosity and hydraulic conductivity/permeability
As part of an integrated logging solution, BMR can combine with other logs in Geotechnical, Hydrogeology, Mining and Geothermal applications
