Abstract:
The present invention provides a methodology and system for formation boundary detection ahead and around of a drilling bit. By setting symmetrical design of receivers/transmitters around a transmitter/receiver and the direction of the receivers/transmitters, the system can measure the signals reflected by a formation boundary ahead of and around the drilling bit. The measured signals can be used to determine formation boundary positions.

Claim (Index 18):
The device of  claim 1 , wherein when there are two receivers, the device is used to determine boundary information through calculations comprising one or more of average(V(\u03c6)), ratios V \ue8a0 ( \u03d5 ) average \ue8a0 ( V \ue8a0 ( \u03d5 ) ) , V 1 \ue8a0 ( \u03d5 ) V 2 \ue8a0 ( \u03d5 ) , V 2 \ue8a0 ( \u03d5 ) V 1 \ue8a0 ( \u03d5 ) , V 1 \ue8a0 ( \u03d5 ) - V 2 \ue8a0 ( \u03d5 ) V 1 \ue8a0 ( \u03d5 ) + V 2 \ue8a0 ( \u03d5 ) , V 1 \ue8a0 ( \u03d5 ) - V 2 \ue8a0 ( \u03d5 ) V 2 \ue8a0 ( \u03d5 ) \ue89e \ue89e and \ue89e \ue89e V 1 \ue8a0 ( \u03d5 ) - V 2 \ue8a0 ( \u03d5 ) V 1 \ue8a0 ( \u03d5 ) , the boundary information comprises one or more of boundary positions, trends, and formation resistivity in both sides of boundaries, wherein \u03c6 is the device's rotation angle, V 1 (\u03c6) and V 2 (\u03c6) are measurements of two receivers with respect to the angel \u03c6, V(\u03c6) is total response of receivers, V(\u03c6)=V 1 (\u03c6)\u2212V 2 (\u03c6), or V(\u03c6)=V 1 (\u03c6)+V 2 (\u03c6), average(V(\u03c6)) is the average of the V(\u03c6).
