Abstract: In this contribution some `areas for exploration in electromagnetic modelling and inversion' are discussed, the focus being on applications in the evaluation and monitoring of subsurface fossil energy reservoirs in the Earth. Three topics receive attention: (1) the modelling of electromagnetic wavefields in strongly heterogeneous media (such as rock), for which the domain-integrated field equations method is presented as a tool, (2) the feasibility of carrying out inversion in the time Laplace-transformed domain at a set of real, positive, values of the transform parameter to which Lerch's uniqueness theorem of the one-sided, causal Laplace transformation applies, and (3) a general operator formalism that is based on the iterative decrease in the norm of the mismatch in data equation and object equation as they occur in the contrast source formulation of the inversion problem.
