Abstract
This paper presents some research studies of the rotary drilling of oil shale at the Bureau of Mines Oil-Shale Mine, Rifle, Colo. The experimental procedures and the rotary drill test equipment are described. Theories of rock drillability, rotary bit cutting action, and bit design are presented and discussed. The actions of various bit designs are analyzed and compared with the observed results of actual drilling tests. A cost estimate is made for drilling Colorado oil shale.
