Patent ID: 7884612

Claim:
A multi-component field source for surveying subterranean formations, comprising: at least two electrodes having a direction of motion, wherein each of the two electrodes is associated with a corresponding different position control fish, wherein a position of each of the position control fish is dynamically controllable to control a position of a corresponding one of the electrodes, wherein the at least two electrodes are configured to produce an electric dipole in an orientation that is not substantially parallel to both the direction of motion of the electrodes and a seafloor, and wherein the electric dipole has at least a first component in a first direction and a second component in a second direction, and wherein the at least two electrodes are configured to transmit electromagnetic energy into the subterranean formations to cause signals to traverse through the subterranean formations underneath the seafloor for receipt by a receiver, wherein the first component is a vertical component and the second component is a horizontal component.
