A Novel Technique for Improved Identification of Reservoir Flow Units of Heterogeneous Reservoirs
A new technique is developed to provide better identification of reservoir flow units constituting the producing formation. This technique is based upon considering fluid, rock, rock-fluid properties and flow mechanics of oil reservoirs. Actual reservoir data of porosity, permeability, oil/water relative permeability, air/brine capillary pressure are used to test the validity of this technique and also to compare obtained results with other techniques such as; permeability-porosity correlation, the J-function, and the Reservoir Quality Index (RQI) concepts.The results indicated that permeability-porosity correlation can not be developed for severe heterogeneous reservoirs. The results showed that the Reservoir Quality Index concept is capable of identifying the flow units while the J-function concept is quiet poor. Furthermore, a more refined and harmonic identification of flow units is obtained for all identified flow units by using the newly-developed technique. The new technique also is capable to provide information about the connectivity of different flow units through the inter-well regions.
