I’ve been looking up some information on oil tanks. It seems the only openings on the tanks are called thief hatches where you can go and take samples of the crude oil or whatever is in the tank. According to what I am finding, these openings are very small - some only 8-12 inches. This could be one of the reasons the girls were placed in the tanks and a challenge to recover and why SW was left in a field. I haven’t seen any other openings on the tanks that could be accessed.
Here is an UNRELATED YouTube video that shows someone taking oil samples and you can see how small the openings are. I don’t know how else he would have gotten them in a tank??
