In conjunction with the Advanced Energy Systems Division of Westinghouse Electric Corporation and the U.S. Department of Energy, Bethlehem Mines Corporation drilled a well near its Cambria Mine No. 32. The purpose of the well was to predrain gas from coal beds ahead of mining and to vent gob gas subsequent to mining through the well. The well was drilled, completed, tested and evaluated under the supervision of INTERCOMP. Fiberglass casing was set through all minable coal beds and the principal coal beds were completed and stimulated. Gas flows were measured and evaluated. Gas quality is good with 98.6% methane. Well evaluation showed abnormally low pressures and no water production. Wellhead shut in pressure of only 26 psig was measured with the bottom completion at a depth of 900 feet. Extended deliverability is predicted to start at 20 Mcfld and decline to 8 Mcf/d over a five year period if the well is produced. The well design and completion procedures demonstrated at this well are significant because they allowed the same well to be used as a gas producer, to be mined through, and to be later used as a gob gas well. The use of the Hydrojet Tool to open the coal zones proved more effective and less expensive then perforating.
