Superior is a leasing agent for an operator. They have been around since June 2021. Possibly for XTO who is an operator in the area. Or could be someone else. I always ask who they are working for.
Another agent in the area is R.D. Williams & Company. Another Lessee is OSO Resources.
Be aware that any lease that you have from an operator needs to be looked at by an oil and gas attorney as the draft lease will not be in the mineral owner’s favor and will need some negotiation.
