Controlled source electromagnetics CSEM is an important tool for hydrocarbon exploration. It is of significant economic interest to transfer some of the concepts and recent successes of marine CSEM to a land-based setting. However, modeling CSEM responses with a grounded source on land requires several adaptations to existing software. The long-term purpose of our work is to develop a reliable forward model for land-based controlled-source electromagnetics which can be used to explore deep resistive hydrocarbon reservoirs in potentially rugged terrain in the presence of oilfield infrastructure and other cultural noise. At the current stage of development, we have adapted an existing finite element algorithm to calculate responses to long dipole excitation of a conducting subsurface with rough topography.
