| 1. A method of developing a reservoir in an earth formation, the method comprising:
(a) conveying a bottomhole assembly (BHA) into a borehole in the earth formation;
(b) obtaining azimuthally sensitive propagation resistivity measurements;
(c) identifying a feature selected from (A) an electrical midpoint, and (B) an electrical saddle-point in the azimuthally
sensitive propagation resistivity measurements; and
(d) identifying a geometric relation of a position of the BHA relative to a bed boundary in the earth formation using the
identified feature.
