Constructing a reduced order model of an electromagnetic response in a subterranean structure

摘要

To construct a reduced order model of a subterranean structure, a model reduction algorithm is applied to produce the reduced order model that is an approximation of a true model of the subterranean structure. The model reduction algorithm uses interpolating frequencies that are purely imaginary to enhance computational efficiency of the algorithm.

applying a model reduction algorithm to produce a reduced order model that is an approximation of a true model of a subterranean structure, wherein the reduced order model models a response of the subterranean structure to an electromagnetic signal, and wherein the model reduction algorithm uses interpolating frequencies that are purely imaginary to provide a real linear system of equations that is solved to produce the reduced order model, where the real linear system does not include imaginary terms; and generating, using the reduced order model in response to an electromagnetic signal of at least one electromagnetic transmitter, synthetic data that represents a simulated version of an expected response of the subterranean structure.
