SYSTEM AND METHOD FOR DETERMINING INFORMATION RELATED TO SUB-SURFACE GEOLOGICAL FORMATIONS USING TIME-DEPENDENT MAGNETIC FIELDS

摘要

A time-dependent magnetic field and/or flux is implemented to determine information related to geological formations within the geologic volume of interest. Such information may include one or more of location, boundary or shape, pressure, faults, lithology, strength, and/or other information. A source of the time-dependent magnetic field and/or flux may leverage the operation of an excavation tool used to excavate a hole at or near the geologic volume of interest in order to generate the magnetic field and/or flux. A plurality of different sources may be used to generated the magnetic field and/or flux.
