Sandridge Energy Inc Company Profile

SandRidge Energy, Inc. is an oil and natural gas company with a principal focus on exploration and production activities in the Mid-Continent and Rockies regions of the United States.

Complementary Operating Areas. Our primary areas of operation are the Mid-Continent area of Oklahoma and Kansas and the Niobrara Shale in the Colorado Rockies. In the Mid-Continent, we are able to (i) leverage technical expertise in the interpretation of geological and operational opportunities, (ii) take advantage of investments in infrastructure including electrical infrastructure and saltwater gathering and disposal systems and (iii) opportunistically grow our holdings through acquisitions, farmouts and operations in this area to achieve production and reserve growth. We are developing a proven oil resource play on our Rockies acreage similar to that being developed by industry in Colorado’s DJ Basin, as both areas draw from the oil rich Niobrara Shale. We will continue to apply our core competencies in developing medium depth formations in the Rockies by deploying our expertise in multi-stage fracture stimulation, artificial lift and extended and multi-lateral horizontal wellbore designs. Additionally, as operator of a majority of our wells, we can further apply competitive advantages to deliver strong, sustainable returns.

Mississippian Formation. The Mississippian formation is an expansive carbonate hydrocarbon system located on the Anadarko Shelf in northern Oklahoma and southern Kansas, and is a key target for exploration and development within the Mid-Continent. The top of this formation is encountered between approximately 4,000 and 7,000 feet and lies stratigraphically between various formations of Pennsylvanian age and the Devonian-aged Woodford Shale formation. The Mississippian formation can reach 1,000 feet in gross thickness and have targeted porosity zone(s) ranging between 20 and 150 feet in thickness.

The estimates of oil, natural gas and NGL reserves in this report are based on reserve reports, which were largely prepared by independent petroleum engineers. To achieve reasonable certainty, the Company’s reservoir engineers relied on technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data used to estimate our proved reserves include, but are not limited to, well logs, geological maps, seismic data, well test data, production data, historical price and cost information and property ownership interests. This data was reviewed by various levels of management for accuracy, before consultation with independent petroleum engineers. Such consultation included review of properties, assumptions and any new data available. The Corporate Reservoir department’s internal reserves estimates and methodologies were compared to those prepared by independent petroleum engineers to test the reserves estimates and conclusions before the reserves estimates were included in this report.
