Natural fractures is the elastic sequence were observed in only two of the <br />• four holes. WSC 87 had one calcite filled vertical fracture, noted at 352 foot <br /> depth. WSC 86 had evo short calcite lined fractures at 295 and 331 foot depths <br />and an open, close-set, parallel, hi-angle fracture system at 393 to 395 foot <br />depths. Rare thin limestones and, in one wse siltstone, exhibited calcite <br />filled dessieation cracks and, more rarely. wogs. None of the lithologiea <br />eacountered in these ezploratory holes showed the grain size, porosity, or <br />permeability characteristic of aquifers. <br />Additional hydrologic information vas gained when I attempted to complete <br />the WSC 86 as a vertical degassification hole. A packer was set on one inch <br />tubing at 337 feet at the top of the 'C' coal seam. Helow the packer. the <br />open hole section being tested consisted, in descending order of 6.0 feet of <br />'C' seam coal; 56.2 feet of generally thin interbedded shale, siltstone and very <br />• fine to fine grained sandstone with some inclusions and thin inter-layers of <br />mudstone; 13.2 feet of Upper 'B' Seam coal; 6.7 feet of interbedded shale and <br />siltstone; 2.7 feet of Lower 'B' Seam coal; and 1.25 inches of phosphoritic sand <br />at the base of the Lower 'B' Seam. <br />While testing this open hole section over a time period of several months, <br />we established a stabilized water floe of 1/3 gallon per minute. It must be <br />understood that the lifting energy for this water production was the flow of <br />methane gas being produced frog the coals. The open hale system had a stabil- <br />ized shut-in pressure of 210 pounds. Repeated observations of gas and water floes <br />from this hole established that, after being opened, the hole would flow dry gas <br />for from 15 to 27 minutes, then start surgiag eater at a rate of 1/3 gallon per <br />minute. Apparently during the shut-in period, the ambient open hole pressure <br />• 2.04-25c <br />
