At last month’s SPE Annual Technical Conference and Exhibition in Denver, Paradigm and French Petroleum Institute (IFP) unit Beicip-Franlab presented the results of a joint study on improved production forecasting with geologically-constrained history matching. The study has resulted in a commercial offering, combining history matching technology from Beicip’s OpenFlow with Paradigm’s Skua interpretation flagship.
The history matching engine inside Beicip’s OpenFlow suite is Condor—a.k.a. constrained description of reservoirs. Condor was originally developed by an IFP-led consortium. Condor eschews the ‘classic’ history matching approach of manual iteration on selected parameters. Instead, a geostatistical inversion technique is used to match dynamic flow data with different iterations of the static geological model in Skua.
Condor identifies and adjusts key parameters contributing to model uncertainty such as PVT, porosity, permeability and fault transmissibility. Parameter variability is propagated through the workflow to ensure consistency between Skua and the dynamic reservoir model. Paradigm CTO Jean-Claude Dulac said, ‘We have combined Skua’s geological uncertainty modeling with OpenFlow to allow for coupled workflows between the geological and engineering models.’ More from www.oilit.com/links/1111_28 (Paradigm) and www.oilit.com/links/1111_29 (Beicip).
