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!
