Patent ID: 6864684

Claim:
A method for recovering a volume of hydrocarbons from a hydrocarbon-containing reservoir in subterranean strata comprising a process of locating the boundary of the hydrocarbon-containing reservoir comprising: (a) deploying an electromagnetic transmitter, (b) deploying an electromagnetic receiver; (c) applying an electromagnetic (EM) field to the strata using the transmitter; (d) detecting the EM wave field response using the receiver; (e) analyzing the response to determine the presence or absence of a hydrocarbon-containing reservoir; (f) moving the receiver to another location along a path, whereby the path taken by the receiver in moving from location to location is being determined by the signal characteristics of previously detected EM wave field responses; and (g) repeating the steps c-e; and producing the hydrocarbon volume from a well that penetrates the hydrocarbon-containing reservoir within the boundary derived from the process of locating the boundary of the hydrocarbon-containing reservoir.
