Variability of Incised Valleys and Estuaries Along French Coasts: An Analog to Oil Reservoirs Where Topography Influence Preservation Potential?

The stratigraphy of incised valleys and estuaries sediment infill is the topic of many studies and international publications since the beginning of the 1990’s [Dalrymple, 2006]. The growing interest for incised valleys and estuaries partly arises from the fact that they represent key objects for sequence stratigraphy analyses at the land-sea transition. This is particularly important in the perspective that numerous oil reservoirs, including those of the Mc Murray formation, are made up of sand-dominated bodies forming part of incised valley fills.
