ABSTRACT:
A method and system are described for determining the dip of subsurface formations penetrated by a borehole. The well is logged using a borehole tool that has at least three antennas spaced approximately equally around the borehole tool for transmitting electromagnetic energy into the earth and receiving electromagnetic energy therefrom. Each antenna array contains a single transmitting antenna and a single receiving antenna. Individual signals are generated representative of the characteristics of the electromagnetic energy detected by each individual receiving antenna. These signals are then compared one to the other to determine the dip of the subsurface formations penetrated by the borehole.
