Reservoir Evaluation Of Fractured Cretaceous Carbonates In South Texas

Many methods have been used to identify natural fracture systems occurring in production reservoirs. These methods have provided only limited capability for determining the extent and producibility of fractures. However, with the present increased interest in fractured reservoirs, a better method of evaluation is needed. This paper discusses one potential method, the Fracture Identification Log. After a review of some of the earlier methods used to identify fractures, this paper will evaluate the Fracture Identification Log method by comparisons with core analyses and production. The initial results are encouraging and have shown this presentation to be a useful technique for evaluating natural fractures.
