Abstract
Methods and apparatus for measuring pollutants contaminating earth formation. Specifically, the invention involves the three dimensional, spatially continuous imaging of sub surface conditions using electromagnetic induction techniques. The technique utilizes the resistivity of near surface volumes of earth formation in order to determine and graphically represent the magnitude and migration of pollutants. Included in the invention are the logging techniques and apparatus as well as the method of converting the captured data into a pseudo resistivity log suitable for a three dimensional imaging of sub surface conditions.
