GeoResources uses the term “non- proved potential”, which SEC guidelines strictly prohibit the Company from including in SEC filings. These non-proved potential reserve estimates tabulated to the left were prepared by management and the Company’s technical staff in accordance with industry practices. Non-proved quantities estimated herein are imprecise forward-looking statements and substantially less certain than proved reserves. All reserve estimates are inherently imprecise and are subject to material revisions based on numerous factors, including drilling success, production history and oil and gas price changes. You are urged to read closely the disclosures in the Company’s Annual Report on Form 10-KSB/A for the year ended December 31, 2007, and GeoResources’ other SEC filings. |
