INTEGRATED OUTCROP AND SUBSURFACE STUDIES OF THE INTERWELL ENVIRONMENT OF CARBONATE RESERVOIRS: CLEAR FORK (LEONARDIAN AGE) RESERVOIRS, WEST TEXAS AND NEW MEXICO

We have completed 18 months of this project and are reporting progress we have made in the areas of fracture and reservoir modeling. Task 1a: Construct Model of Outcrop Stratigraphic Framework has been completed. Task 1b: Construct Model of Fine-Scale Petrophysical Heterogeneity has been completed. Task 1c: Construct Model of Fracture Porosity and Permeability the object of this task is to characterize fracture porosity and distribution in the Wasson Clear Fork reservoir and to determine the effects of fractures on well performance. The approach is to measure fracture attributes in an analog outcrop, to develop models of fracture spacing and aperture, and to apply this information to the South Wasson Clear Fork reservoir. A data set has been collected from outcrops of the Clear Fork Formation, Apache Canyon, Sierra Diablo Mountains, West Texas, and a summary of the results is presented
