Abstract:
The present invention provides a methodology and system for resistivity tool design. By using at least one E field antenna instead of magnetic antennas, stronger signals can be captured by a smaller system. The more effective antenna design of the present invention has broad applications in various tools including geosteering, look ahead, and triaxial induction.
