Some of the more fascinating relics on TM are the old drilling sites. No telling how much stuff is scattered out in Jenks and Glenpool. There was also quite a bit of exploration in Red Fork around the same time.
Thousands of wells. I see old pictures from time to time of old wooden derrick fields and while not sure where most of them are, this link shows the Ida E Glenn well and field.
http://www.glennpooloilfield.org/history/There is an old well in the riverbed (Arkansas) south of I-44. Got some good pictures of it one time during low water. If I knew how to post pics, I would put them up here. There are some spools of cable, an old engine of some sort, casing broken over with some production tubing inside, and what looks like some kind of tank thing - maybe a separator - "bolted" together with large rivets. Looks ancient, but can't be more than about 100 years old.
Lived about 4 blocks from Rogers high school for a few years and there was always rumors about oil wells under the area. I am pretty sure there was some coal mining near there, 'cause one of the neighbors said he had done some strip mining there in the teens. He moved back in the area after the war when the neighborhood was being built (late 30's to late 40's except WWII).
Seems like I heard rumors about wells on the old Mayo Farm, but that may be somewhere else - don't think there was a whole lot there... (Mayo Meadows...south of 21st, west of Yale. Across from fairground.)
