Groundwater & Aquifer Evaluation Using NMR Well Logging
Granite Geophysical provides Nuclear Magnetic Resonance (NMR) well logging services for groundwater and water well projects. Borehole NMR logging delivers direct measurements of water-filled porosity, pore size distribution, permeability, and hydraulic conductivity, providing critical data for aquifer evaluation, well design, screen placement, and groundwater flow and transport modeling. NMR logging is especially effective in unconsolidated sediments and fractured aquifers where conventional logs alone cannot reliably quantify hydraulic properties.
