Biography

Born and raised on his family’s working cattle ranches in South Texas and Eastern New Mexico, Reagan is no stranger to hard work, long hours, and enjoying the fruits of labor.

It is no coincidence that Reagan’s award-winning practice focuses on representation of large land and mineral owners, including mineral and royalty funds and, high net worth families, non-operating working interest owners, and investors in energy litigation and transactions throughout Texas and New Mexico.

In his energy litigation practice, Reagan’s experience ranges from multimillion-dollar title and oil and gas disputes in the Eagle Ford Shale and Permian Basin to renewable and alternative energy contract disputes along the Gulf Coast.

In his energy transactional practice, Reagan is particularly well known for helping Texas and New Mexico landowners and companies develop, produce, sell, or dispose of their non-traditional natural resources including water (saltwater disposal agreements, freshwater sales contracts, and water joint operating agreements); sand (sand and gravel leases, sand supply contracts, and sand mine purchase and sale agreements); sun (solar leases); wind (wind leases); and carbon (carbon sequestration agreements).

Outside of the office—which is where Reagan prefers to spend most of his time—Reagan is a cattleman, a hunter, and a fisherman.

If you ask Reagan’s wife (Allison) or his sons (Billy and Wiley) what the family motto is they will reply, “To always be kind.” More than anything, Reagan takes pride in being a kind, professional, and ethical advocate in the courtroom and the boardroom.

Litigation

Reagan’s oil and gas litigation experience is extensive including successfully obtaining summary dismissal of and defending on appeal an operator’s adverse title claims in which the plaintiff claimed over $100 million in damages and successfully prosecuting claims against an operator that it had improperly deducted costs from a landowner’s royalty.

Reagan has handled several renewable energy disputes ranging from settling a dispute for a confidential amount of money on behalf of a renewable energy developer in which a prospective partner circumvented the developer and cut it out of the deal to successfully resolving a dispute between an oil and gas company and a solar farm.

Transactions

Reagan has negotiated and drafted tens of thousands of acres of water leases and disposal agreements on behalf of both landowners and developers, drafted custom operating agreements between working interest partners on water wells, negotiated and drafted several multi-million dollar purchase and sale agreements for acquisitions of sand producing properties and sand leases, negotiated and drafted dozens of wind and solar leases, and has negotiated several carbon sequestration agreements.
