Cable Tool Drilling Rig
Drilling is accomplished by an engine driving a belt or "band" which turns the band wheel. As the band wheel rotates, a crank on the band-wheel shaft connected by a pitman to one end of the beam rocks the beam up and down. The temper screw hangs from the other end of the walking beam and is clamped around the drilling cable. Cable is stored on the bull wheel from which it leads up through the derrick to the sheave on the crown block and then back down to the temper screw. The actually weight of the drilling operation is carried by the walking beam and temper screw. As the walking beam rocks up and down, a chisel-shaped bit on the bottom end of the cable is raised and dropped, pulverizing the rock at the bottom of the drill hole. The rock cuttings are removed by hoisting the bit out of the hole and lowering a bailer down the hole. The bailer is a hollow tube with a simple valve on its lower
These rigs were capable of drilling to a depth greater than 9,000 feet. Over 300,000 wells in the United States were drilled with cable tools before the advent of rotary rigs. Many of Wyoming's important oil and gas fields were discovered and developed using rigs similar to this one.
The deepest cable-tool hole in Wyoming is the Resolute Oil Co. #1 Northern Pacific Railroad located in the SW NE Section 17, T. 57N., R. 101W., Park County. It took three years from 1928 to 1931 to reach a total depth of 8,723 feet. This well was the discovery for Badger Basin Field. It initially flowed 55 barrels per day of 50 degree API gravity oil and 250,000 cubic feet of gas per day from the Upper Cretaceous Frontier formation.
Erected 1993 by Petroleum Association of Wyoming.

Also see . . . Oil Well - Wikipedia. The earliest oil wells in modern times were drilled percussively, by repeatedly raising and dropping a cable tool into the earth. In the 20th century, cable tools were largely replaced with rotary drilling, which could drill boreholes to much greater depths and in less time.
