dc.description.abstract Relatively little is known about marine controlled -source electromagnetic surveys (MCSEM ) used to detect hydrocarbon reservoirs . Typical MCSEM require the use of inversion to generate a model of the subsurface . We utilize a 3D finite -element forward model to simulate a MCSEM survey . With the results we were able to determine the strengths and weaknesses of each transmitter and receiver configuration that would best detect a shallow hydrocarbon target . Careful selection of the correct configuration is important as we have found that incorrect transmitter orientation , offset and receiver measurement component can yield misleading results . Using the ideal configuration we were able to directly image the hydrocarbon target without the use of inversion modeling . The direct image is able to show the hydrocarbon target's shape and edges without any ambiguity . The direct image of the target can potentially be used to refine 3D inversion modeling , or be used in conjunction with seismic profiles to refine seismic picks . en_US
