- Summary:
- The Devonian shale resource which underlies much of Appalachia and was the formation of interest in Kentucky and West Virginia is discussed. The CEF process is described which consists of pumping two non-detonable chemical streams down the well bore to a mixer where the liquid explosive is manufactured. The explosive is displaced down the tubing to the bottom of the well and out into the formation rock. It detonates in thin films as well as in the borehole thus fracturing the rock and increasing the permeability. Site selection, pre and post shot flow tests, cleanout and production results are presented. The problems encountered are discussed. Evaluation led to modified and improved placement, initiation, and cleanout techniques. Projected costs for the improved simulation and cleanout technique are presented. Additional tests to determine the caging/springing effect in the borehole are planned by Petroleum Technology Corporation.
