the area described is almost level. The wells in section 26 be- 
long to the Oread Oil and Gas Company and those in section 
27 to the Kansas Crude Oil Company. The well called Kansas 
Crude No. 1 was drilled to a total depth of 880 feet. At 768 
feet 10 feet of sand was found, which was practically barren 
of oil. At 833 feet 5 feet of sand was found which was rich 
in oil, and at 844 feet 12 feet of sand was encountered that was 
productive. The base of this sand was at 856 feet. Below this 
point 16 feet of shale was passed through, then 5 feet of sand, 
which produced close to one million feet of gas per day. The 
drill went 3 feet farther in light-gray shale and was then 
stopped. 
Oread well No. 1 is situated 300 feet due east of the well 
just described. In it 8 feet of sand rich in oil was encoun- 
tered at 764 feet, corresponding fairly well with the 10 feet 
of sand in the Kansas Crude well. Below it 62 feet of shale 
was passed through and then 14 feet of productive oil-sand, 
corresponding very well with the 12-foot bed of sand in the 
first well described. After passing 9 feet in shale the drill 
was stopped, as it was not desired to reach the gas which, ac- 
cording to the record of the Kansas Crude well, might be ex- 
pected below. 
Oread well No. 2 was located 400 feet south of Oread No. 
1. Ata depth of 798 feet 25 feet of sand was found, which 
produced a large quantity of gas. Below this 4 feet of black 
shale, partly saturated with oil, was passed through, and then 
18 feet of productive oil-sand, the bottom of which was 839 
feet below the surface. It will be noted that in this well no 
sandstone was found at a depth of 770 feet where, according 
to the records of the other wells, it might have been expected, 
‘ while a bed of gas-bearing sand 25 feet thick was encountered 
at 798 feet, no trace of which was found in either of the other 
two wells. 
The next well drilled was Oread No. 8. In it no oil was 
found, but a strong flow of gas was obtained from a sand ata 
depth of about 800 feet, doubtless corresponding to the gas- 
sand found in well No. 2. 
Well No. 4 was located 400 feet south of No. 2. In ita 
productive oil-sand was reached at 835 feet, corresponding to 
the oil-sand in the other three wells | 
Well No. 5 was located 400 feet south of well No. 4. At 800 
feet a small flow of gas was obtained, and at 808 feet 13 feet
