Exploration and development of Middle and Upper Devonian organic shales in the Cottageville gas field of western West Virginia began in the late 1920s. Continued development has lead to the drilling of over 110 shale wells with accumulative production of more than 10 billion cubic feet of natural gas. Data indicate primary production from zones of organic shales in the Lower Huron Member of the Ohio Shale Formation. Due to the extremely low porosity (3 to 4 percent) and permeability (less than 0.1 millidarcy) of these shales, gas production is considered to be through natural fracture systems. These fracture systems have partially been delineated through the study of oriented cores. Historically, production of gas has been through natural completion or by stimulation with gelled nitroglycerine. Varied success of this stimulation technique has recently led to more advanced types of stimulation (hydraulic and foam fracturing). Total production, natural gas flow trends, final gas flow trends, and structural breaks and trends have led to the delineation of the fractured shale reservoir. Careful examination of these parameters can lead to the exploration and development of successful shale wells within and near the gas field. 36 figures, 10 tables.
