  • Patent number: 4780857
    Abstract: A borehole logging tool is rotated within a borehole and also advanced along the borehole. A log of the formations surrounding the borehole is recorded. An interval of the borehole intersected by a formation fracture is identified on the recorded log. The fracture dip angle and dip direction are determined from the location of the center of the fracture with respect to the borehole and the peak amplitude and phase angle of the recorded borehole signal at the fracture location.
