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.
