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 1):
An electromagnetic Logging While Drilling (LWD) device, comprising:\n (i) one or more transmitters configured to emit electromagnetic wave, each of said transmitters is a magnetic antenna transmitter, an electric antenna transmitter or a magnetic-electric antenna transmitter; and (ii) one or more receivers configured to measure one or more electric field parameters, each of said receivers is a magnetic antenna receiver, an electric antenna receiver or a magnetic-electric antenna receiver; wherein said transmitters and receivers are mounted on a conductive mandrel, said receiver(s) is configured to have a measurement or combined measurements that is (1) weak or zero in homogeneous medium, and (2) reflective of an existence of formation boundaries ahead and/or around the LWD device, and said LWD device measures one or more formation parameters selected from the group consisting of resistivity, permeability, and distance to a boundary.
