BMR - Borehole Magnetic Resonance
Borehole Magnetic Resonance, BMR, is a downhole geophysical logging technique that directly measures the hydrogen contained within subsurface fluids, allowing in-situ quantification of water within geological formations.
The method provides estimates of total porosity, mobile fluid content, bound fluid content, and permeability. These parameters can be used to evaluate aquifer characteristics and derive hydraulic conductivity, supporting groundwater resource assessment and hydrogeological investigations.
Applications
Hydrogeological Characterisation
Identifies water bearing zones and supports hydrogeological characterisation by helping assess groundwater occurrence and movement.
Porosity Estimation in Iron Ore Environments
Provides quantitative total porosity and porosity distribution information for porosity estimation in iron ore environments.
Environmental Monitoring
Supports environmental monitoring by providing information on groundwater occurrence and subsurface fluid distribution.
Dry Bulk Density Estimation
When combined with density logging, BMR can support dry bulk density estimation.
Permeability and Hydraulic Conductivity
Provides permeability estimates that can be converted to hydraulic conductivity, supporting groundwater flow and dewatering assessments.
Dewatering and Water Inflow Management
Supports water inflow control and dewatering system management by identifying intervals associated with groundwater occurrence.
Well Test Replacement
Calibrated BMR data can support well test replacement by providing downhole information on porosity and hydraulic properties.
Heap Leaching
Supports heap leaching studies where porosity, permeability and fluid movement are important.
In-Situ Recovery and Brine Mining
Supports assessment of porosity, permeability and groundwater conditions for ISR uranium, ILR lithium and brine mining applications.
Groundwater Production and Injection
Supports groundwater production and injection studies by providing information on porosity, permeability and water bearing intervals.
Tailings and Ground Stability
Supports tailings and ground stability studies where pore fluid distribution and groundwater conditions are important.
