摘要:Maximizing resource extraction from mature oilfields requires enhanced and secondary recovery techniques. The success of these methods relies on knowledge and understanding of the reservoir geology and hydraulics. At the Loudon Oilfield (Illinois, USA), enhanced oil recovery is being used to extend the production life of the reservoir. The suitability and placement of additional wells for oil recovery processes required three-dimensional (3D) facies and porosity modeling of the oilfield. The purpose of this work was to assess the ability of a porosity model to predict sandstone facies. The facies model for the Loudon field was generated using data obtained from digitized-wireline logs. The facies model provided sand thickness and insight in the geometries and interconnections of the producing formations. The porosity model identified zones of high porosity, and illustrated the discontinuous nature of the porosity zones within the oilfield. Comparison of facies and porosity models revealed strong correlation and similarity between the models.
