From 1978 to 1990, Mr. Barnes worked in the oil and gas industry for upstream exploration and production companies. He received his law license in 1989 and began practicing law in 1990. Since then his practice has focused primarily on employment law, commercial litigation, and appeals. A substantial portion of his commercial litigation practice has involved oil and gas matters, representing producers, royalty owners, overriding royalty owners, oilfield service companies, and pipeline operators. Mr. Barnes has handled lawsuits involving a host of issues related to the upstream oil and gas business including royalty disputes, pooling clauses, easements, operating agreements, drilling contracts, preferential rights to purchase, title issues, and areas of mutual interest. In the employment area, Mr. Barnes regularly handles matters involving covenants not to compete and employment contracts.

His practice has involved representation in connection with the preparation and review of oil and gas leases and other transaction documents for both royalty owners and producers. Mr. Barnes has represented clients in connection with both the acquisition and the divestiture of oil and gas properties. He has also represented and advised clients in connection with negotiating and drafting of drilling contracts, oil and gas leases, gas purchase contracts, and property purchase and sale agreements to name a few.

In addition to the transactional and appellate practice areas, Mr. Barnes also has experience in negotiating employment agreements and various business contracts. As a result, Mr. Barnes has earned an outstanding reputation, combining his oil and gas work and corporate and commercial law skills.

Mr. Barnes currently holds an “AV” rating with Martindale-Hubbell, which is its highest rating, and is based on evaluation by his peers in the legal profession.
