Abstract
A repeat seismic survey has been planned in 2013 to support and to optimize the EOR field development of a mature, heavy oil field, offshore Sabah using water and ASP injections. This 4D seismic is to repeat the 1996 3D seismic as the base line. The 4D seismic is aimed to detect contact movements after 12 years of production, to identify un-swept parts of the main reservoir, to verify connectivity’s between compartments, to identify gas break-out and to optimize placements of water and ASP injectors. A few studies addressing the 4D signal detectability and survey repeatability have confirmed the feasibility of the project.
