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 14):
The apparatus in accordance with  claim 11  or  12 , wherein least one of\n the position of the plurality of transmitter (TX) electrodes and \n the transmitted current pulses from the plurality of transmitter (TX) electrodes is, by use of the computer program product, adjusted iteratively during the recording of the measurement signals u i  in order to optimize sensitivity to at least one geological characteristic m k  of a given geological target.
