Title: Preliminary analysis of Devonian shale oil production in the Appalachian Basin

Abstract

Devonian shale production has been continuous for many years in the Appalachian Basin. In the northwest portion of West Virginia and the southeast area of Ohio, the shale produces liquid hydrocarbons. A few wells have reported initial potentials (IP's) in excess of 1000 barrels per day (bpd). Inherent to this unconventional resource (low pressure, low permeability, low porosity, and naturally-fractured) is a rapid rate of production decline such that, after 4 to 6 months, many wells become inoperable. The US Department of Energy's (DOE's) Morgantown Energy technology Center. (METC) anticipates investigating the occurrence of liquid hydrocarbons in the shale, as well as the reservoir engineering and fluid properties aspects. DOE/METC intends to offer producers in the area information, techniques, and procedures that will optimize liquid production. Besides new well drilling ventures, results of the investigation should affect the approximately 2000 shale wells that are already completed but are plagued by a rapid decline in production. Ideally, these older wells will be regenerated, at least to some degree, leading to further resource exploitation. This report summarizes some of the available production data, characterizes decline rates for selected wells, and specifies a refined study area of high resource potential. 11 refs., 14more » figs., 1 tab.« less
