Review paper: Instrumentation for marine magnetotelluric and controlled source electromagnetic sounding
We review and describe the electromagnetic transmitters and receivers used to carry out magnetotelluric and controlled source soundings in the marine environment. Academic studies using marine electromagnetic methods started in the 1970s but during the last decade these methods have been used extensively by the offshore hydrocarbon exploration industry. The principal sensors (magnetometers and ...
متن کاملSpecial Section — Marine Controlled-source Electromagnetic Methods an Introduction to Marine Controlled-source Electromagnetic Methods for Hydrocarbon Exploration
Early development of marine electromagnetic methods, dating back about 80 years, was driven largely by defense/military applications, and use for these purposes continues to this day. Deepwater, frequency-domain, electric dipole-dipole, controlled-source electromagnetic CSEM methods arose from academic studies of the oceanic lithosphere in the 1980s, and although the hydrocarbon exploration ind...
متن کامل3-D controlled source electromagnetic interferometry by multidimensional deconvolution
Controlled Source Electromagnetic (CSEM) is an important technique in hydrocarbon exploration, because it uses the large contrast in electrical resistivity to distinguishes between water and hydrocarbons. In a shallow sea environment, the airwave that is refracted from the air-water interface dominates the recorded signal at large offsets. Therefore, the hydrocarbon detection ability of the CSE...
متن کاملSeismic and electromagnetic controlled-source interferometry in dissipative media
Seismic interferometry deals with the generation of new seismic responses by crosscorrelating existing ones. One of the main assumptions underlying most interferometry methods is that the medium is lossless. We develop an ‘interferometry-bydeconvolution’ approach which circumvents this assumption. The proposed method applies not only to seismic waves, but to any type of diffusion and/or wave fi...
متن کاملControlled source electromagnetic interferometry by multidimensional deconvolution: Spatial sampling aspects
We review electromagnetic interferometry by multidimensional deconvolution (MDD) and investigate its sensitivity to spatial sampling. Two Sea Bed Logging datasets were modeled numerically. One represents a shallow sea situation with a small vertical source-receiver distance and the other a deep sea situation with a large vertical source-receiver distance. The reflection response from below the ...
