FIG. M-5. Marmousi model. A 2D seismic model devised by the Institut Français du Petrole to test 2D migration algorithms. There is a hydrocarbon accumulation (and flat spot) in the anticline under the decollement. (a) The model at 1:1 scale ratio[1]; (b) model with different grey density indicating different velocities: (c) CMP stack of the seismic data. (d) Time migration of the CMP stack; (e) Prestack depth-migration of 1% of the data[2].

(mar moo’ sē) A complex 2D structural model and its seismic response devised by the Institut Français du Petrole, used to compare depth-migration and velocity determination models. It involves strong horizontal and vertical velocity changes[1].
