Abstract:
A method and apparatus for offshore electromagnetic surveying for the purpose of hydrocarbon exploration and detection is described. The method comprises the step of A) measuring a measurement vector u between receiver electrodes, where the measurement vector u comprises a plurality of measurement signals u i , being dependent on a geological characteristic m k  at an geological parameter index k providing information about the geological structure of the geological target area. The method is further characterized in that it also comprises the following steps: B) calculating a transformed vector v as a function of the measurement vector u, where said transformed vector v is designed to optimize the sensitivity to changes in the geological characteristic m k  and C) performing, for each time t, at least one of minimizing uncertainty δv(k,t) of the transformed vector v with respect to the geological characteristic m k , where said uncertainty δv(k,t) comprises a non-systematic uncertainty δv′(k,t) and a systematic uncertainty Δ wd v(k,t), maximizing a target response ∂v(k,t)/∂m k  of the transformed vector v with respect to the geological characteristic m k  and minimizing a ratio ψ(k,t) between at least the square of the non-systematic uncertainty <δv′(k,t) 2 > of the transformed vector v and the square of the target response (∂v(k,t)/∂m k ) 2  of the transformed vector v with respect to the geological characteristic m k .

Claim (Index 8):
The method in accordance with  claim 6 , wherein the step A and the step of measuring locations of said receiver electrodes are performed simultaneously, or near simultaneously.
