Hydrocarbon Reservoir Modelling

Improved geological models aiding hydrocarbon reservoir development and management.

The decision-making process in the hydrocarbon business is tied to the reliability of any geological models used to underpin reservoir flow-simulation and economic models. Research on the Ainsa sedimentary basin in the Spanish Pyrenees by Prof Kevin Pickering has allowed industry to explore for hydrocarbons more effectively in deep-marine sandstone reservoirs in hydrocarbon provinces around the world.

Hydrocarbon Reservoir Modelling

An integrated outcrop-subsurface study of the deep-marine sandy submarine-fan deposits in the Ainsa basin was funded by a consortium of oil  (NPD), including Conoco, BP, ExxonMobil, NorskeHydro-Statoil, TotalFinaElf and Philips Petroleum.
