The natural gas production is gaining importance as a clean source of energy. Several potential sources exist for gas production in the Appalachian Basin with the Marcellus shale being the largest resource in the U.S. This covers several states in the Eastern U.S. and plays a vital role in the future of gas production. As a result operators are interested in the development of the shale resources mostly with multi-stage fractures using a horizontal well. However, the lack of commercially available information on well and treatment designs is rather vague. This information is critical in the determination of economics of gas production from shale wells.

In this study, simulations have been conducted to determine the gas production from horizontal shale wells when limited data is used in the design of fracturing operations. Some of the parameters studied include horizontal and vertical stresses, the amount of fracture stages and formation properties along with others. The same treatment can yield different fracture geometry due to changes in formation properties; however, the gas production values after a single fracture treatment were similar for cases considered in this study.
