Alta Mesa Resources, Inc. is a publicly traded (NASDAQ: AMR, AMRWW) independent exploration and production company 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. The STACK is an acronym describing both its location—Sooner Trend Anadarko Basin Canadian and Kingfisher County—and the multiple, stacked productive formations present in the area. The STACK is a prolific hydrocarbon system with high oil and liquids-rich natural gas content, multiple horizontal target horizons, extensive production history and historically high drilling success rates. Alta Mesa has assembled a large, highly contiguous leasehold position, largely in the up-dip, naturally-fractured oil portion of the STACK in eastern Kingfisher County, Oklahoma. The Company has identified over 4,000 gross horizontal drilling locations, at least half of which it expects to operate. These drilling locations are in Alta Mesa’s primary target formations comprised of the Osage, Meramec and Oswego. Alta Mesa opportunistically acquires acreage in its non-operated locations with the goal of operating wells in these locations. Alta Mesa has a seasoned management team, and the company apply advanced engineering analyses and enhanced geological techniques to under-developed or over-looked conventional resource areas to create value.
