Abstract: A method of modeling a subsurface hydrogeologic system within a study area can include applying an electric current directly to the subsurface hydrogeologic system and monitoring a magnetic field generated by the electric current in the subsurface hydrogeologic system. An electric current distribution can be identified within the study area by an inversion process based on the magnetic field. A model of the electric current distribution can be created.

Abstract: A system for measuring magnetic fields outside a ferromagnetic container from inside the same container is described. The invention uses magneti circuits to direct the flow of magnetic flux to a magnetic field detector. By using magnetic fields for detection, this invention is able to measure the properties of magnetic materials outside the ferromagnetic container, such as a geologic formation, electric or magnetic parameters, or log well and drill holes that have been cased.

Abstract: A magnetic method is disclosed that can be used to map, track and monitor the progress of secondary oil recovery during water or steam floods. An electric current is injected directly into the water hydrocarbon system to be monitored. The electricity that flows in the water creates a magnetic field, which can be monitored. Monitoring the changes in the magnetic field monitors the changes in the water flooding the subsurface hydrocarbon zone. The resulting surface magnetic field is measured at various time intervals. Variation in magnetic field is used to interpret and determine the status of the hydrocarbon recovery zone.

Abstract: An electromagnetic method is disclosed that can be used to map, track, and monitor subsurface water or solutions and related geologic structure including: groundwater, groundwater channels, groundwater structures, subsurface pollution plumes, locate the source of springs or seeps, map interconnected fracture or porous zones, map leaks in earthen dams, map leaks in drain fields, monitor changes in subsurface water flow, monitor changes in ion concentration in groundwater, monitor in situ leaching solution, monitor movement of heap leaching solutions, monitor changes in subsurface redox or reaction fronts, monitor underground chemical reactions, monitor subterranean bioreactions, or other subsurface waters and related geologic structures. An electric current is injected directly into the water or solution that is to be mapped, tracked, or monitored. It is also necessary to provide a return path for the injected electrical current.
