About Millennium Exploration

Millennium Exploration Company, LLC is a privately held oil and natural gas exploration and production enterprise founded in 2006, and is headquartered in San Antonio, Texas. Geographically focused, Millennium specializes in developing and producing reserves in the Gulf Coast regions of Texas.

Company History

Millennium Exploration Company was founded by Mr. Richard Monroy in July of 2006 as a fully integrated oil and gas exploration group. Mr. Monroy assembled a team of experts to conceive, drill, complete and manages high quality oil and gas prospects. Mr. Monroy started his career as a licensed broker selling oil and gas interests for two local brokerage firms before branching out independently. Through the years his knowledge of oil and gas prospects grew from the financing side, spilling over to the areas of geology, engineering and field operations management. Armed with this knowledge, Mr. Monroy took his savings and purchased an interest in a North Texas oil well launching what would become Millennium Exploration Company.
