About Us

Arkose Petroleum

Formed in 2015, Arkose began acquiring mineral and royalty interests primarily in the Eastern Midland Basin. Since that time, Arkose has expanded its focus to acquire mineral and royalty interests throughout the entire Permian Basin. Our team conducts title searches, provides valuations, prepares paperwork and quickly funds and completes transactions.


Prior to forming Arkose, the management team began their relationship while working at Big Star Oil & Gas, a local independent oil and gas operating and production company.  Big Star aggregated a sizeable leasehold position, primarily in Howard County and in 2016 successfully marketed and sold its position to Callon Petroleum.  After the sale to Callon in mid-2016, Arkose Management, LLC was co-founded by Jared Atchison, Ross Roach and Kathy Myers for the purpose of acquiring mineral and royalty interests in the Permian Basin.
