There are a couple documentaries on this topic. I did a quick google search looking for one I watched about 6 months ago but could not find the specific one, but there were many in my search you should look into.

One of the parts was a rancher lady who bought a ranch in texas to raise cattle on. She did not realize at the time there were a bunch of uncapped, abandoned wells on the property. She did not figure it out until she started to explore the hundred of acres over the year after purchase.

Many were never abandoned properly and now push up oil and/or methane. There are federal funds to now take action, but the funding is significantly under what's needed. The other thing is water will often infill the wells and start daylighting with an oily water mix. It's a huge mess left by the petroleum industry since it started.

Consider hiring a geologist or another type of investigation group to look over the property and develop a report for ya.
