PROBE FOR COLLECTING GEOPHYSICAL LOGGING DATA

摘要

The present invention related to a probe for use in collecting geophysical logging data for subterranean strata. The probe includes a charging assembly having a current input wire and current electrode for transmitting an electrical charging current to the strata to form an electrically charged strata and a signal reception assembly including a plurality of potential wires and associated potential electrodes for transmitting electrical potential readings from the electrically charged strata. The probe including an outermost insulating jacket substantially encasing the charging assembly and the signal reception assembly, wherein the current wire is electromagnetically insulated from the plurality of potential wires.
