The average oil recovery rate in reservoirs is 35% with current technologies. To increase field recovery, it is essential to improve reservoir characterization.
A good knowledge of sedimentary heterogeneities and their spatial distribution, as well as reservoir properties, makes it possible to optimize the layout of producing and injecting wells and the selection of the chemical additives to be used.
Research at IFP Energies nouvelles hinges around the development of software enabling better integration of the information available, with a view to having an increasingly reliable representation of reservoirs.
Work is notably being carried out on interactive modules for geostatistic filling and scaling of petrophysical properties grouped together within CobraFlow™ software. IFP Energies nouvelles has also developed modules for the static and dynamic characterization of fractured reservoirs, within FracaFlow™ software. This software proposes methods for the estimation of petrophysical parameters, along with methods for characterization of fracture networks.
Reservoir simulation is another key factor in terms of improving recovery. A version of the PumaFlow™ reservoir simulator dedicated to chemical enhanced recovery is under in the development.
It will make it possible to conduct quantitative chemical EOR studies, such as ASP (Alcaline Surfactants polymers) with advanced physics. In addition, a version dedicated to CO2 EOR is also currently being examined.
The knowledge acquired is transferred to a software platform named OpenFlow™. The OpenFlowSuite™ software suite, marketed by Beicip-Franlab, incorporates TemisFlow™, PumaFlow™, FracaFlow™, CobraFlow™, CondorFlow™ and CougarFlow™ software.
