ABSTRACT:
A method for detecting fractures in a formation penetrated by a borehole wherein the fracture is first filled with a magnetic material and the formation then logged with an instrument that responds to the earth's magnetic field. The fracture can be filled with a magnetic material by including it in the drilling mud when the well is drilled and changing the mud system before logging. The logging tool can comprise a simple compass or a magnetometer.
