Resistivity Surveys and Tools
The purpose of electrical resistance surveys is to determine the subsurface resistivity distribution from the ground surface. This is accomplished using various arrays of surface electrodes that can transmit currents and measure precise voltage changes. From these measurements, the true resistivity of the subsurface can be estimated. The ground resistivity is related to various geological parameters such as the mineral and fluid content, porosity and degree of water saturation in the rock. Electrical resistivity surveys have been used for many decades in hydrogeological, mining, geotechnical, and environmental subsurface investigations.
Induced polarization is an exploration method involving measurement of the slow decay of voltage in the ground following the cessation of an excitation current pulse. This method makes use of the capacitive action of the subsurface to locate zones where clay and conductive minerals are disseminated within their host rocks.
Applications for Resistivity
Contamination delineation, cavity and sinkhole detection, groundwater exploration, lithology mapping, mineral exploration, archaeological site investigations, time lapse monitoring of remediation processes, time lapse monitoring of injection processes, dam leakage detection, salt water intrusion, bedrock depth, fracture locations.
Applications for Induced Polarization
Mineral exploration, clay delineation, NAPL (LNAPL or DNAPL) delineation, landfill detection, site characterization for metallic rich sediments.
