103046 – New Barnett Shale Horizontal Completion Lowers Cost and Improves Efficiency

Summary

Over the last few years horizontal completions of the Barnett Shale have advanced in an attempt to better stimulate the entire horizontal interval. One standard completion process, where the horizontal is cased and cemented, has emerged. This process is very costly and time consuming, with the added risks of having to remove the composite plugs, plus there is no viable method for re-stimulating these wells at a later date. A new completion system has been deployed in over 300 wellbores in various producing formations, such as sandstone, limestone, shale, dolomite and coal. With a multitude of jobs completed to date in the Barnett Shale, this paper will analyze the operational efficiencies, cost benefits, reliability and production data of this completion system compared to the standard completion practices being implemented today.
