Paris Basin offers opportunities for unconventional hydrocarbon resources

Applying basic concepts and methods used on unconventional plays elsewhere, such as the Bakken Shale and Barnett Shale of the USA, we have identified three possible unconventional hydrocarbon plays in the Paris Basin, France: the Lias Shale oil play, the Permo-Carboniferous Shale gas play, and the Upper Carboniferous coalbed methane play. Analysis based on IHS proprietary data and public sources indicates the presence of a thick sequence of Palaeozoic sediments. We have constructed a preliminary stratigraphic succession of the Palaeozoic sediments and mapped their distribution, which could help in exploration of the Palaeozoic reservoirs as an extension of known conventional petroleum systems. Our analysis of the Paris Basin indicates that the basin still holds good hydrocarbon potential, both for conventional and unconventional plays, and merits a new phase of exploration, especially considering its excellent infrastructure and recent advances in technology.
