' All water level data is derived from log data collected prior [o placement of casing unless o[herwise noted.
Z Four-inch steel casing set at 421 ft. and annulus sealed with 13 bags of cement. Open hole dolled to TD at
453 ft. Interval open is 421-453 ft. and the strata exposed aze 15 ft. of shale and siltstone, l0 ft. of coal, and
7 ft. of shale and siltstone.
' Surface casing set at 18.5 ft. Four-inch steel casing set at 3l9 ft. and annulus sealed with 13 bags of cemen[.
Open hole drilled to TD at 372 ft. Interval open is 319-372 ft., and the strata exposed in descending order
are: 9 ft. of siltstone, 12 ft. of interbedded siltstone and sandstone, IO ft. of shale, 9 ft. of coal, 13 ft. of
shale and siltstone.
° Surface casing set at 30.9 ft. Four-inch steel casing set at 297 ft. wi[h bottom capped and perfora[ed from
62 ft. to 276 ft. Water was encoun[ered a[ about 72 ft. during drilling. Estimated discharge during drilling
was 15 gpm.
