Enterprise Oil Ltd and Norsk Hydro A/S joined this project in 1993 as industrial partners. The project aims concerned problems being faced when producing from high porosity, low permeability fractured chalk reservoirs and other fractured limestone reservoirs. The aims, goals and methods put forward in the proposal and later outlined in interim reports, could give very valuable input to how geological models are built, and how these complicated reservoirs are produced and managed in which the understanding of 3-dimensional fracture interconnectivity and spatial distribution is the key to a successful field development. The dual porosity permeability system poses two main problems: the siting of production wells; and of injection wells. In this type of reservoir the producers must intersect several of the major fractures to secure acceptable production rates from the rock volume. Injection wells, if wrongly placed can result in rapid advance of injected water towards producers, isolating potentially recoverable hydrocarbons in the fracture-bounded rock matrix. These hydrocarbons are then almost impossible to recover. This report outlines a method for modelling fractures in 2-dimensions and 3-dimensions from a 1-dimensional dataset, and how this can be incorporated in a flow simulation model. This method will assist in planning the development of such reservoirs and in optimizing the reservoir performance during production.
