Enhanced Two Dimensional Inversion
25 Feb 21
A method for characterizing a subterranean formation, the method comprising: performing electromagnetic logging measurements along a portion of a borehole traversing the subterranean formation using an electromagnetic logging tool to obtain electromagnetic data; determining one or more initial approximations for one or more electromagnetic properties associated with a two dimensional imaging plane modeling the subterranean formation; determining one or more initial approximations for a relative orientation between the two dimensional imaging plane and an orientation of a trajectory along the portion of the borehole; and performing a first inversion using (i) the one or more initial approximations of the one or more electromagnetic properties, (ii) the one or more initial approximations for the relative orientation between the two dimensional imaging plane and the orientation of the trajectory, and (iii) the electromagnetic data to estimate an orientation of the two dimensional imaging plane relative to the orientation of the trajectory.
