The Company


Principle Energy was formed in 2005 by Richard Hamilton, its President and CEO with a vision to bring transparency and integrity to this industry in a way that is truly beneficial to both mineral owners and Principle Energy.  Our expertise and on-hand capital have enabled us to successfully close thousands of mineral and royalty interest transactions where we have consistently paid premium prices to landowners.

Since its inception in 2005, Principle Energy has acquired tens of thousands of acres in Alabama, Arkansas, Colorado, Louisiana, Mississippi, Ohio, Oklahoma, Texas and Wyoming. Our continued success is rooted in our reputation for treating landowners fairly, paying top dollar and streamlining the closing process. Our talented team of experienced professionals makes selling your mineral or royalty interest a smooth and simple process.

At Principle Energy we take pride in delivering personal attention to each and every landowner we encounter. When doing business with us, you can rest assured knowing that you will never be in the dark at any point during the process. Any questions or concerns that you may have will be promptly answered by our team.

As a company, we demand a high level of both personal and corporate integrity. We truly value the rights and dignity of the landowner and place them higher on our priority list than making a quick dollar.

If you want to reduce your exposure to the risks of the Oil & Gas market and explore the possibility of a lump sum cash payment for your mineral or royalty interest, Principle Energy may be able to help.
