STATE COLLEGE, Pa.Feb. 3, 2014 (GLOBE NEWSWIRE) -- Rex Energy Corporation ("Rex Energy") (Nasdaq:REXX) today announced its total estimated proved oil, NGL and natural gas reserves as of December 31, 2013.

Estimated Proved Reserves

Rex Energy reported proved oil and natural gas reserves as of December 31, 2013 of 849.8 Bcfe, an increase of 37% over December 31, 2012. Of the 849.8 Bcfe of proved reserves, 39% was attributable to oil, natural gas liquids and condensate, assuming 55% ethane recovery. The proved developed portion of the reserves increased to 356.5 Bcfe from 257.9 Bcfe as of December 31, 2012. The proved reserves estimates as of December 31, 2013were prepared by the company's independent reservoir engineers, Netherland, Sewell & Associates, Inc. Rex Energy successfully replaced 923% of its estimated production of 33,850 Mcfe for the twelve months ended December 31, 2013 with a proved reserves-to-production ratio of 25.1 years.

Note on Hydrocarbon Volumes and Estimates
The estimates of proved reserves in this release are based on a reserve report of our independent external reserve engineers as of December 31, 2013. "Proved reserves" are estimates that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions (see Rule 4-10(a) of Regulation S-X for the SEC definition of "proved reserves"). The SEC permits publicly-reporting oil and gas companies to disclose "proved reserves" in their filings with the SECSEC rules also permit the disclosure of "probable" and "possible" reserves. Rex Energy discloses proved reserves but does not disclose probable or possible reserves. We use certain broad terms and other descriptions of volumes of potentially recoverable hydrocarbons in our public statements. These broad classifications do not constitute "reserves" as defined by the SEC and we do not attempt to distinguish these classifications from probable or possible reserves as defined by SEC guidelines. We are prohibited from disclosing hydrocarbon quantities that do not constitute reserves in documents filed with the SEC.
We believe the data we prepared and supplied to our external reservoir engineers in connection with their preparation of the 12/31/2013 reserve report, and the assumptions, forecasts, and estimates contained therein, are reasonable, however, we cannot assure that they will prove to have been correct. Estimates of reserves can be affected by inaccurate assumptions or by known or unknown risks and uncertainties.
Finding and Development Cost
Finding and Development Cost per unit of production is a non-GAAP metric used by the industry, investors and analysts to measure the company's ability to establish a long-term trend of adding reserves at a reasonable cost. Drill-Bit Finding and Development Cost is defined as the sum of total capital deployed, less lease acquisitions and other related expenditures, divided by total extensions and discoveries. All-In Finding and Development Cost is defined as the sum of total capital deployed divided by the sum of extensions, discoveries, acquisitions, divestitures, conversions, and revisions, less the prior period's production. The calculations presented by the company are based on unaudited costs incurred excluding estimated abandonment costs. For purposes of consistency with current calculations, we have revised certain amounts relating to prior period Capital Deployed and Finding and Development Cost. All financial results are unaudited.

Reconciliation of Standardized Measure to PV-10
PV-10 is a non-GAAP metric used by the industry, investors and analysts to estimate of the present value, discounted at 10% per annum, of estimated future cash flows of our estimated proved reserves before income tax and asset retirement obligations The following table shows the reconciliation of PV-10 to our standardized measure of discounted future net cash flows, the most directly comparable GAAP measure, for the years ended December 31, 2011, 2012 and 2013. Management believes that PV-10 provides useful information to investors because it is widely used by professional analysts and sophisticated investors in evaluating oil and natural gas companies. Because there are many unique factors that can impact an individual company when estimating the amount of future income taxes to be paid, we believe the use of a pre-tax measure is valuable for evaluating our company. PV-10 should not be considered as an alternative to the standardized measure of discounted future net cash flows as computed under GAAP.

These preliminary estimates may be revised in connection with the preparation of our financial statements for the year ended December 31, 2013.
