In the area of electromagnetic simulation, the Finite Element Method (FEM) is one of the most widely studied and used. However, when it must be used to solve a direct problem nested within an inversion algorithm, the efficiency of the direct solver must be the driving factor for any implementation. The electromagnetic problem to be solved is a boundary problem with some known sources in a non-homogeneous arbitrary medium.
We developed and implemented a formulation in 2.5D, which assumes that media do not vary along one direction, designed specifically for its use in an inverse problem such as the CSEM technique exploited for seabed logging applications.
The short seminar will cover the basic principles of CSEM, the 2.5D formulation and its Matlab implementation with some application examples.
