About Us
Oklahoma people, doing Oklahoma things
Rising Sun Energy, LLC became a reality in 2018 with a goal of building a mineral, non-op leasehold, and overriding royalty portfolio within the state of Oklahoma. We believe in honest, fair, and transparent transactions, and we pride ourselves on doing the right thing above all else.

Our Vision
We understand that the Oil & Gas industry is one that can be complex and overwhelming for many mineral owners. Our goal is to help make that process less intimidating by working with land owners one-on-one, and explain the process every step of the way.
With nearly 20 years of experience in the industry, our team works diligently to make every transaction as seamless and simple as possible. We pride ourselves on being “Oklahoma people, doing Oklahoma things”.
