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<br>environments. The Gulfs of Mexico and Guinea are typical areas for which investment in seismic monitoring raises no<br>questions. However, in other areas, such as carbonate fields, the question is less clear, because the physical behavior of<br>carbonate rocks is difficult to describe accurately. Very few examples of 4D monitoring in carbonate environments can be<br>found in the literature.
