Alta Mesa Resources, Inc. (formerly known as Silver Run Acquisition II) is a publicly traded independent exploration and production company which was formed in early 2018 by combining the core upstream assets of Alta Mesa Holdings, LP with the gas processing assets of Kingfisher Midstream LLC. Alta Mesa Resources is focused on the development and acquisition of unconventional oil and natural gas reserves in the eastern portion of the Anadarko Basin referred to as the STACK. Alta Mesa has assembled a large, highly contiguous leasehold position and has identified more than 1,000 gross horizontal drilling locations in the Osage, Meramec and Oswego formations. The Kingfisher midstream facility primarily focuses on providing crude oil gathering, gas gathering and processing and marketing to producers of natural gas, NGLs, crude oil and condensate in the STACK play and has an energy asset network that includes over 300 miles of existing low and high pressure pipelines, a 60 MMcf per day cryogenic natural gas processing plant, 10 MMcf/d in offtake processing with a 200 MMcf per day cryogenic processing plant under construction. This gathering and processing system is strategically positioned for growth in the highly active STACK play, which is expected to face takeaway constraints as a consequence of increased drilling activity and improving well results. Alta Mesa has a seasoned management team, whose mission is to maximize the profitability of its assets in a safe and environmentally sound manner. The Alta Mesa team applies advanced engineering analyses and enhanced geological techniques to drive discipline investment.
