How to verify a well doesn't enter your property undergrond

My family and I own several sections outside the town of Plains. It has been leased but currently is not leased. A well has been drilled on the section between ours (by the company that last leased our property) really close to our property line. How do we verify they are not taking oil from under our property? Is there a setback for a well to keep it at a distance to another property to ensure minerals are not being taken from beneath the adjacent property? How do we ensure they have not gone horizontally into our property? Any guidance would be greatly appreciated!

I think this was answered in another location, but the state has setback rules to prevent drainage from nearby properties. You can check the RRC site to see where the wells lie with respect to your property. Once the well is drilled, there will be an “as drilled” plat where you can see the path of the well.
