(210 pounds) would force the water away from the bore hole. As pressure dropped <br />• during flow, the water would enter the bore hole and become entrained in the gas <br />flow to surface. <br />I am convinced for the following reasons that the pressure and dry gas <br />production can be attributed directly to the coals; that the water production <br />can be attributed to the intervening clastic sequence: <br />1) Analysis of the produced water (attached) indicates that the <br />source of the water was the clastic sequence.High total dis- <br />solved solids (8532 mg/L) in this water are not typical of waters <br />produced f2om coals which usually are of such low total dissolved <br />solid content as to be potable. <br />2) Observation of gas breakthroughs while drilling and [he extensive <br />desorption tests of the coal definitely ties the methane production <br />to the coals. <br />3) The highly transmissible cleat and butt fracture systems observed <br />throughout the coals offer the only system possible to explain the <br />relatively high stabilized shut-in pressure and the flow performance <br />of this hole. <br />4} In order to gain additional insight into the hydrologic questions <br />raised by WSC lf6,we analyzed water from two other sources in the mine. <br />A sample of roof seep water in the subslope was collected and analyzed <br />and a sample of standing water from WSC /f5 was collected after continuous <br />bailing for about 1/2 hour. These analyses are attached. The striking <br />similarity of these analyses to the water from WSC !f6 as to pH, total <br />dissolved solids, and constituent ratios again strongly suggest that <br />• the source of the water is the clastic sequence rather than the coals. <br />
