Definitely a western photo. Texas, Wyoming, California.
All three are of the same location.
I worked 4 years on Drilling rigs. 3 in Texas and 1 in California in the early 80's.
Got to see an old cable tool rig in operation once. Pretty neat to watch. The pipe hanging in second photo appears to be the BIT. (can't be positive without seeing the end of it) Surface pipe is set in the bottom photo with the cable running down.
Rigs generally had 2 bits. They would sharpen one, while the other was drilling.
roadrelics is so right about it being hard, dangerous work, even today.
Had an old timer tell me, Oil Drilling was one of three occupations during WWII, that the government didn't expect women to work in, to replace men sent to war, because it was so dangerous and vital to the war effort. Having a job in those fields would keep you home. He said Coal Mining and Steel Worker were the others. Don't know how true, but makes sense.
Thanks for posting hillsideshortleg. Love these old pics.
