FOR IMMEDIATE RELEASE

Cardinal Energy Signs Definitive Purchase Sales Agreement with Kansas Petroleum

‘Purchase Agreement Sets Terms and Conditions for the Prospect’s Acquisition’

Dublin OH, August 21, 2013 - (OTCQB: CEGX) Cardinal Energy Group, Inc. announces the signing of a definitive and binding Purchase Sales Agreement with Kansas Petroleum Resources, LLC on August 19, 2013 to purchase a 100% working interest in oil and gas leases that cover approximately 17,000 acres of land and include 19 oil and gas wells located in Pawnee and Hodgeman Counties, Kansas in addition to other operational assets of Kansas Petroleum. The acquisition is part of management’s ongoing plan to build a portfolio of oil and gas properties in the Continental United States that are poised for further development. The wells to be acquired are located within the oil producing zones in Kansas known as the Mississippian limestone formation, Lansing-Kansas City limestone formation, the Cherokee Sand Basin and the Permian Chase Group formations. Upon completion of the acquisition, Cardinal’s annual oil production will increase by at least 300 barrels of oil per day.

Commenting on the agreement Timothy Crawford, CEO of Cardinal, stated “We are excited to move forward with our acquisition of the Kansas Petroleum assets, as this marks a milestone in the growth of Cardinal. The assets include 3D Seismic surveys, 19 vertical oil-producing wells, along with 2 water disposal wells which have been drilled into the Arbuckle formation. Utilizing these assets we plan to acquire, we believe that we can double the field’s production. Further, we believe that the addition of these assets will allow us to continue with our expansion strategy as we position our company to meet our expectations for the future in this important industry. Completing this acquisition poises us to take advantage of the improving pricing trends to fuel substantial growth for Cardinal in the coming years.”

About Cardinal Energy Group, Inc.

Cardinal Energy Group, Inc. is a U.S producer of oil and natural gas within the United States. The Company is based in Dublin, Ohio. Cardinal focuses on known formations that have significant proven reserves remaining that can be produced economically. Cardinal targets fields with wells that may need remediation due to neglect or under capitalization. We select prospects that offer a strong up-side for production. The upside we seek in a prospect is twofold – it must have the potential to be restarted or have its current production increased using newer technology and remediation methods and; it must also have additional lease acreage which can be further developed by completing development wells adjacent to existing producing wells. Cardinal exploits these undervalued assets by acquiring a majority working interest in the prospect and then applies the Company’s calculated development plan. Cardinal also seeks acquisitions of over-leveraged companies when there is a clear upside from their purchase based on strong commodity prices. The Company operates throughout the Continental United States. More information on Cardinal Energy Group, Inc. is available at www.cardinalenergygroup.com.
