Abstract
An array of electromagnetic receiver antennae is arranged and operated in conjunction with the operation of an array of far field electromagnetic transmitter antennae for mapping subsurface features of an existing well site reservoir. Mapping is performed according to the relative intensities, frequencies, phase shifts, and/or other reflected signal parameters of the reflections received by the receiver antennae (relative to the transmit signals) associated with a given location or target area within a reservoir so as to aid in determining the geological features about an oil deposit for an existing oil well.
