Devonian Sands in north-central West Virginia can have as many as 13 productive intervals. Because of the high treating pressures on fracturing jobs, placing designed sand loads into some of these formations can be difficult. Recently, fracturing designs required improvement in these areas to successfully stimulate the reservoir while remaining within economic constraints. Improved analysis of digital log data coupled with reservoir-production review has resulted in improved completion designs, and stimulation engineers are now able to optimize fracture designs for each of the identified primary zones. The authors present past completion practices followed by the new completion designs and show the increase in production achieved. Recommendations for further improvements are also made for future West Virginia operations.
