DOI: 10.1016/j.marpetgeo.2018.11.008
Abstract: Abstract The grid chosen for marine controlled-source electromagnetic forward modeling and inversion is important because it affects the accuracy and efficiency of the latter. Providing these kinds of results is particularly difficult for offshore exploration.… read more here.
