METHOD FOR SUBSURFACE ELECTROMAGNETIC SURVEYING USING TWO OR MORE SIMULTANEOUSLY ACTUATED ELECTROMAGNETIC SOURCES

摘要

A method for electromagnetic exploration includes imparting a first electromagnetic signal into subsurface formations from a first location and imparting a second electromagnetic signal into the formations from a second location substantially contemporaneously with imparting the first electromagnetic signal. The first and second electromagnetic signals are substantially uncorrelated with each other. A combined electromagnetic response of the formations to the first and second imparted electromagnetic signals is detected at a third location. A response of the formations to each of the first and the second imparted signals is determined from the detected response.
