SEAM Update

SEAM Phase I RPSEA is in the process of completing a suite of geophysical simulations on the geophysical model representative of a salt area of the deep-water Gulf of Mexico. Part of this interdisciplinary effort includes the simulation of two types of electromagnetic acquisitions over the SEAM model, one for a controlled-source electromagnetic (CSEM) and one for magnetotelluric (MT). Both CSEM and MT 3D modeling and imaging technologies are of intense interest to companies conducting exploration and reservoir development in marine environments. SEAM's goal is to provide 3D electromagnetic data that not only mimic current field acquisitions but, in most cases, far exceed them. The resulting simulation data can be used to validate and ultimately improve 3D EM forward modeling as well as subsurface imaging and characterization methods using electromagnetic data alone or when combined with other types of geophysical data. © 2012 by The Society of Exploration Geophysicists.
