ISAP phase 2 mooted at SPE Miri applied technology workshop

TNO’s computer-aided history matching JIP leverages JOA Jewel Suite and CMG’s flow modeler.

Speaking at the recent SPE Applied Technology Workshop in Miri, Malaysia, researchers from the Netherlands-based TNO organization provided an update on TNO’s Integrated System Approach to Petroleum Production (ISAPP), with focus on improving production from channelized reservoirs. TNO presented an integrated workflow for forecasting production from reservoirs with complex geometries and inter-channel connectivity.

The preferred history matching technique is an ensemble Kalman filter (EnKF) that has been integrated with JOA’s JewelSuite’s Impala multi point statistics property modeling functionality to simulate multiple geological realizations. These are then evaluated for flow performance using CMG’s simulation tools.

The approach is said to be amenable to reservoir control in the light of increasing information streaming from the digital oilfield and intelligent wells. The resulting ensemble of history-matched models is then used for production forecasts and uncertainty analysis. EnKF came out of TNO’s program of fundamental and exploratory research into closed-loop concepts and computer-assisted methods. The first ISAPP program concluded in 2009. TNO is now inviting interested companies to participate in phase 2 of the research effort. The (noble) goal is to increase oilfield recovery by ‘10% or more,’ using ‘improved methods and concepts into the reservoir management workflow.’ More from
