(TU Delft Applied Geophysics and Petrophysics) Mulder, W.A. (TU Delft Applied Geophysics and Petrophysics; Shell Global Solutions International B.V.) Slob, E.C. (TU Delft Applied Geophysics and Petrophysics) Date 2019 Abstract Controlled-source electromagnetic (CSEM) surveys are a common geophysical investigationtool in the search for, amongst other, groundwater, hydrocarbons, and minerals. The nu-merical modelling of CSEM data requires the solution of the Maxwell equations. These canbe simplified in the particular case of CSEM, as the frequencies used in surveys are usuallysufficiently low to ignore any displacement currents. A diffusive problem remains, which hasthe resulting system of equations given in the frequency domain byE To reference this document use: http://resolver.tudelft.nl/uuid:6d2649ac-f537-4d0c-98bd-5a6799b5c5b6 DOI https://doi.org/10.21105/joss.01463 Source Journal of Open Source Software Part of collection Institutional Repository Document type journal article Rights © 2019 D.
