Abstract
The invention provides for systems and methods of enhancing crude oil recovery providing an array of electromagnetic receiver antennae arranged and operated in conjunction with an array of far field electromagnetic transmitter antennae for mapping subsurface features of a 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. Such mapping aids in determining an optimal location of a production well or the location of an auxiliary well relative to the production well.
