Marine
Control Source ElectroMagnetics
Marine
controlled-source electromagnetic (CSEM) surveys have been
developed recently as a means for detecting and delineating
hydrocarbon reservoirs situated in sea beds. Although some
theoretical work exists that establishes the principles
of the marine CSEM method, much remains to be understood
about its practical applicability. Our work seeks to
establish the conditions under which marine CSEM is feasible.
The reserch uses a set of geo-electrical models derived
from actual exploration projects, and assumes commonly used
acquisition geometries and realistic noise levels. Theoretical
development is performed for 1-D geo-electrical sections,
and numerical modeling is carried out for 2-D and 3-D problems.
