Abstract:
1. A method of processing formation survey data generated using an array of physical transmitters and an array of physical receivers, the method comprising: (i) producing excitations in the formation using the array of physical transmitters; (ii) detecting the excitations using the array of physical receivers to generate survey data; (iii) calculating a weighted sum for the array of physical transmitters, wherein the weighted sum comprises a weight for each of the physical transmitters; (iv) calculating a compressed data set for the survey data in which a number of physical transmitters is reduced by the weighted sum to a number of representative transmitters in the compressed data set, wherein calculating the compressed data set comprises constructing the compressed data set of L (L<M,N) transmitters ( wherein M is the number of physical transmitters, N is the number of physical receivers, L is the number of representative transmitters in the compressed data set, J i is the weighted sum for represents the M physical transmitters, and v k,i provides transmitter weights; (v) performing an inversion using the compressed data set; and (vi) outputting a result of the inversion in tangible form.
