An Integrated Approach to the Modeling of Permeability Barrier Distribution in a Sedimentologically Complex Reservoir

In a complex clastic reservoir of glaciodeltaic origin - the target for a steam-drive pilot project - low permeability ‘baffles’ seen in cores are difficult to correlate between wells. Their distribution is estimated probabilistically incorporating analogue outcrop data. The resulting model was used to calculate effective vertical permeability to oil, water and steam and to construct a 2-D reservoir simulation model used to determine optimum injection intervals.
