Statements concerning future revenues and expenses, production volumes, results of exploration, exploitation, development, acquisition and operations expenditures, and prospective reserve levels of prospects or wells are forward-looking statements. Prospect size and reserve levels are often referred to as "potential" or "un-risked" reserves and are based on the Company's internal estimates from the volumetric calculations or analogous production. Other forward-looking statements are based on assumptions concerning commodity prices, drilling results, recovery factors for wells, production rates, and operating, administrative and interest costs that management believes are reasonable based on currently available information; however, management's assumptions and the Company's future performance are subject to a wide range of business, mechanical, political, environmental, and geologic risks.
