Contact Buckhead Energy for a free, no-obligation evaluation of your specific mineral interests.

What is the difference between working interest and royalty interest?

A royalty interest (RI) entitles the owner to a share of production revenue without paying for drilling or operating costs. A working interest (WI) participates in both the revenue and the costs of drilling and operating wells. Most mineral owners in Gregg County hold royalty interests.

About Gregg County & The East Texas Oil Field

Gregg County is in East Texas, with Longview as its county seat and Kilgore within its borders. It sits atop the East Texas Oil Field — one of the largest oil fields ever discovered in the lower 48 (1930), producing from the Woodbine sand.

The East Texas Oil Field has produced oil for over 90 years since its 1930 discovery. Production is mature and long-lived, with many wells declining slowly and continuing to pay royalties for decades.

Many mineral owners in Gregg County have received royalty payments for decades. As wells mature and production declines, some owners choose to sell their mineral rights to convert future uncertain income into immediate cash. Buckhead Energy purchases mineral rights across the East Texas Oil Field and broader East Texas Basin.
