Mar 20, 2014 (D Draper) - The Long Rapids Formation shale overlies Williams Island Formation limestone. Williams Island itself is on the northeast-trending axis of an anticlinal structure. The Long Rapids shale form the flanks of this arch, dipping generally northwest or southeast from 18 to 35 degrees. Exposure of shale, up to 50 feet high are frequent over a 5-mile stretch of river in this area.

Mar 20, 2014 (D Draper) - The hydrocarbon is hosted by the middle member of the Long Rapids Formation which consists predominately of black, grey and dark brown bituminous shale with minor thin bands of greenish-grey clay. DDH #12 was drilled to 765ft (dip not given, presumed vertical), intersecting overburden to 108ft, oil shale to 328ft, limestone to 700ft, then a second band of oil shale to 745ft. Last 20ft of hole described only as hard core.

Mar 20, 2014 (D Draper) - Hole 12 intersected a 220 foot section of oil shale immediately beneath overburden (108ft). A second zone, 32 ft in width, was cut at 713ft. Note from log on this lower zone [Q]: Very strong hydraulic pressure, damaged rods and threw up gas and oily water. Gas strong a quarter of a mile away downwind. Everything covered with oil scum around the drill shack. Hole 12 was drilled 900ft south of hole 11, both on the west bank of the river; the other 10 holes in the series were drilled to the west along a 2-mile line parallelling the ONR tracks. Of the twelve holes drilled, 9 encountered black oil shale, the next three best occurrences being: Hole 8--90ft of shale in 4 zones from 59 to 174 feet; Hole 7--72ft over 3 zones from 60 to 183 feet; Hole 6--54.5ft, 1 zone, 109 to 164ft. (AR Vol 37-6 (1928) contains analyses of weathered samples of the shales of [Q] the lower part of Long Rapids [precise location not given]. The samples returned 3.9% and 5.5% oil yield (crude).
