Modelling

In controlled-source electromagnetic surveying, simulation of the propagation of electromagnetic fields in a resistivity model

Forward modelling is used to test geo-model hypotheses in the survey-planning and interpretation stages.

In seismic surveying, modelling is often used informally for the process of “model building”, or constructing a rock property model of the earth, such as a resistivity model.

A modelling study includes both model building and forward modelling, followed by misfit analysis to assess the accuracy of the model.
