Salt Flank Exploration - 3D CSEM Imaging in the SEAM Model

We have simulated a salt flank hydrocarbon reservoir imaging case using the 3D controlled source electromagnetic data from the SEAM phase I model. The complication due to the dominant EM response from the salt body is tackled by a structural constraint. In our simulated exploration scenario, we assumed that seismic imaging provided information to construct an approximate salt structural model but with three types of errors: 1) Limited information below salt overhangs and no base salt, 2) inaccurate lateral and depth positioning, and 3) incorrect salt resistivity. A modeling study and our imaging results demonstrate that the applied workflow is robust against these errors, and the 3D inversion results in a reconstruction that agrees well with the true model reservoir laterally and in depth.
