HOUSTON, Jan. 31, 2012 /PRNewswire/ -- Gastar Exploration Ltd. (NYSE Amex: GST) ("Gastar" or the "Company") today announced its total proved Securities Exchange Commission ("SEC") reserves as of December 31, 2011 and approved its 2012 capital budget.

Proved Reserves

Gastar reported year-end 2011 proved natural gas, oil and condensate and natural gas liquids (NGLs) reserves of 119.7 Bcfe estimated in accordance with SEC regulations. This represents an increase of 138% over year-end 2010 proved reserves of 50.3 Bcfe.  Of the 119.7 Bcfe, 76.6% were attributable to natural gas, 9.6% to oil and condensate and 13.8% to NGLs.  The pre-tax present value discounted at 10% ("PV-10") of the estimated proved reserves increased to $217.1 million from $67.3 million at year-end 2010.  The Appalachian Basin represented 70% of proved reserve volumes and 80% of the PV-10 value with East Texas comprising the majority of the remainder of proved reserves and PV-10 value. 

Proved undeveloped reserves at year-end 2011 represented approximately 34% of total proved reserves compared to approximately 17% at year-end 2010.  Proved undeveloped reserves at year-end 2011 were comprised of 41.2 Bcfe of Appalachia Basin reserves having a PV-10 value of $67.3 million. 

In accordance with SEC regulations, estimates of proved reserves as of December 31, 2011 were made using the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period January through December 2011.  For natural gas volumes, the average Henry Hub price utilized was $4.12 per MMbtu, and for oil volumes, the average West Texas Intermediate price utilized was $92.71 per barrel.  The natural gas and oil prices are adjusted for energy content or quality, transportation and regional price differentials by area.

The Appalachian Basin proved reserves estimates as of December 31, 2011 were prepared by Wright & Company, Inc. Netherland Sewell & Associates, Inc. prepared the East Texas and other areas reserves as of December 31, 2011. 

2012 Capital Budget

Gastar's Board of Directors has approved a 2012 capital budget totaling $134.2 million.  In Appalachia, the Company expects to spend $103.0 million for drilling, completion, infrastructure, lease acquisition and seismic costs.  In East Texas, the Company has budgeted $6.5 million.  In addition, the Company has allocated $19.8 million for a new Mid-Continent oil-focused venture and $4.9 million for capitalized interest and other costs.  Drilling and completion costs represent approximately $100.5 million of the total capital budget, of which $88.9 million, or 89%, will be spent on activities in the liquids-rich window of the Marcellus Shale, and an additional $7.8 million, or 8%, will be directed to drilling the new oil venture.   Gastar anticipates funding this capital activity through existing cash balances, internally generated cash flow from operating activities, borrowings under the revolving credit facility and possible future at-the-market issuances of Series A Preferred Stock by Gastar Exploration USA, Inc. ("Gastar USA"), Gastar's first tier subsidiary and primary operating company.  Gastar exited 2011 with $30 million outstanding under its revolving credit facility and $10.6 million in cash.       

Included in the 2012 capital budget are plans to drill and complete 20 gross (10 net) operated new Marcellus horizontal wells in Marshall County, West Virginia, along with the completion of 10 gross (4.5 net) additional operated Marcellus horizontal wells that were drilled and awaiting completion as of December 31, 2011.  Gastar exited 2011 with 9 gross (4.0 net) operated Marcellus wells completed.

As mentioned above, Gastar has acquired an initial lease position in a new oil play located in the Mid-Continent region and plans to build the position, along with its partner, to approximately 25,000 gross (12,500 net to Gastar) acres in 2012.  Drilling is planned to commence in the second half of 2012 in hopes of developing a program focused on low-cost, repeatable horizontal development of conventional oil-bearing formations.  Three gross (1.5 net) initial horizontal wells are planned to be drilled and completed in this area during 2012.  The Company will provide additional details on this new oil play after Gastar and its partner have acquired sufficient acreage to allow a multi-year development plan to be undertaken. 

Production Guidance

Based on the approved capital expenditure budget, Gastar expects first quarter 2012 production to range from 26 MMcfe/d to 28 MMcfe/d.  Gastar's operated production and sales in West Virginia continues to be impacted by issues with high line pressures on the third-party operated gathering system.  The operator of the gathering system anticipates having the line pressure issues alleviated by early February.  The continued focus on condensate and oil and NGL-rich projects should result in Gastar's first quarter 2012 production profile containing approximately 12% to 16% liquids. 

Preferred Share Issuances

During the fourth quarter ended December 31, 2011, Gastar USA issued 554,044 preferred shares for net proceeds of $10.5 million resulting in year-end 2011 total preferred shares issued of 1,364,543 for net proceeds of $27.4 million.  To date during January 2012, Gastar USA has issued an additional 499,387 preferred shares for net proceeds of $9.4 million, resulting in inception to date net proceeds of $36.8 million.  

J. Russell Porter, Gastar's President and CEO, commented: "This 138% increase in our proved reserves in 2011, and the 223% increase in the PV-10 value of those reserves, reflects the significant success we achieved developing our Marcellus acreage.  It also reflects the benefit of the $40 million drilling carry we utilized during the year in the Marcellus Shale and the benefit of strong oil and liquids prices. 

"By concentrating on developing our liquids-rich acreage, we are raising the percentage of oil, condensate and NGLs in our production profile.  As we test and potentially develop our new oil play in the Mid-Continent, we may have an opportunity to further increase the liquids content of our reserves and production even more substantially."

By issuing forward looking statements based on current expectations, opinions, views or beliefs, Gastar has no obligation and, except as required by law, is not undertaking any obligation, to update or revise these statements or provide any other information relating to such statements.

Gastar's capital budget is subject to revision and reevaluation dependent upon future developments including drilling results, availability of crews, supplies and production capacity, weather delays, significant changes in commodities prices or drilling costs.

Year-end pre-tax discounted present value of proved reserves, or PV-10, is a non-GAAP financial measure as defined by the SEC. It differs from Standardized Measure of Discounted Future Net Cash Flows ("SMOG") in that PV-10 excludes the discounted value of estimated future income taxes.   We believe that the presentation of PV-10 is relevant and useful to our investors because it presents the discounted future net cash flows attributable to our proved reserves prior to taking into account corporate future income taxes and our current tax structure. We further believe investors and creditors use PV-10 as a basis for comparison of the relative size and value of our reserves as compared with other companies.  The discounted value of future income taxes is being evaluated and estimated in connection with completion of Gastar's 2011 financial statements and a reconciliation of PV-10 to SMOG will be included in Gastar's Form 10-K.
