Induction logging device with a pair of mutually perpendicular bucking coils
Patent
·
OSTI ID:5745169
An instrument is disclosed for mapping vertical conductive fractures in a resistive bedrock, magnetically inducing eddy currents by a pair of vertically oriented, mutually perpendicular , coplanar coils. The eddy currents drive magnetic fields which are picked up by a second, similar pair of coils.
