Sandridge Energy Inc
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.
