A deviated well was drilled in a direction selected to maximize the number of natural fractures that might be encountered and to evaluate the deviated well concept for producing gas from the economically marginal Upper Devonian Shale in the eastern United States. The well was drilled to a depth of 4,678 feet (true vertical depth of 3,928 feet) with the average deviation from vertical through the shale section being 40/sup 0/7'. The shale was completed open hole and was shot with 18,700 pounds of gelatin explosive from 2,900 feet to 4,678 feet. Five days after treatment the well exhibited an open flow of 103 Mcfd. Following several months of shut-in, the wellhead pressure had increased to 552 psi and the well was put on production. Production of gas for the three months following shut-in was a total of 1801 Mcf.
