A 2D on 3D pilot for 4D feasibility: A success on a carbonate field

It is nothing unusual now to see decisions taken to record time-lapse seismic surveys in unconsolidated sands or turbidite environments. The Gulfs of Mexico and Guinea are typical areas for which investment in seismic monitoring raises no questions. However, in other areas, such as carbonate fields, the question is less clear, because the physical behavior of carbonate rocks is difficult to describe accurately. Very few examples of 4D monitoring in carbonate environments can be found in the literature.
