Gastar Announces Record Results for the First Quarter of 2008 and Provides Operational Update

HOUSTON, May 12, 2008 (BUSINESS WIRE) -- Gastar Exploration Ltd. (AMEX:GST) (TSX:YGA) today reported financial and operational results for the three months ended March 31, 2008.

During the first quarter of 2008, the Company achieved record production, revenues and net cash flows and recorded a quarterly net profit from operations. Highlights include:

-- Production averaged 26.5 million cubic feet of natural gas equivalent per day (MMcfe/d), a 29% increase over the fourth quarter 2007 and an 88% increase over the first quarter 2007

-- Natural gas and oil revenues, before unrealized natural gas hedge loss, were $16.8 million, a 124% increase over the first quarter 2007

-- Net income was $1.1 million, or $2.5 million excluding the unrealized natural gas hedge loss

-- Net cash flow from operations was $14.3 million

First Quarter Results

Net income for the first quarter of 2008 was $1.1 million, or $0.01 per basic and diluted share, compared to a net loss of $11.0 million, or $0.06 per basic and diluted share, for the first quarter of 2007. The first quarter of 2008 included a $1.4 million unrealized natural gas hedge loss. The first quarter of last year included a litigation settlement expense of $1.4 million and $3.6 million of allowance for doubtful accounts related to litigation that were included in general and administrative expenses. Without the effect of the unrealized hedging loss, net income for the first quarter 2008 would have been $2.5 million, or $0.01 per basic and diluted share, and without the effect of the litigation settlement expense and doubtful account allowance, the normalized net loss in the first quarter 2007 would have been $6.0 million, or $0.03 per basic and diluted share.

Net cash flow from operations was $14.3 million, a significant increase over $281,000 for the first quarter of 2007.

Natural gas and oil revenues increased 124% to approximately $16.8 million, compared to revenues of $7.5 million for the first quarter of 2007. Of the increase, 72% was due to an 88% increase in natural gas production, primarily in East Texas, and 28% of the increase was due to a 19% increase in realized natural gas prices.

Average daily production increased to 26.5 MMcfe/d, compared to 14.1 MMcfe/d for the first quarter of 2007. The average realized price for natural gas, excluding unrealized natural gas hedge loss, increased to $6.96 per Mcf, compared to $5.86 per Mcf in the first quarter of 2007.

During the three months ended March 31, 2008, approximately 44% of our natural gas production was hedged. The effect of hedging on natural gas sales was a realized decrease of $232,000 in revenues, resulting in a decrease in total price received from $7.05 per Mcf to $6.96 per Mcf. An unrealized loss related to hedge accounting of $1.4 million was also incurred, resulting in total revenues of $15.4 million.

Lease operating expense (LOE) was $1.5 million, down from $1.7 million for the first quarter of 2007. LOE per Mcfe decreased 52% to $0.64 per Mcfe during the first quarter of 2008, down from $1.33 per Mcfe for the comparable period in 2007. In East Texas, LOE declined to $0.44 per Mcfe during the 2008 period from $1.14 per Mcfe in the comparable 2007 period. The decrease was primarily due to higher production volumes, lower ad valorem taxes, lower workover expenses and the elimination of costs associated with the leasing of natural gas treatment plants in East Texas.

Weighted average shares of common stock outstanding on a basic and diluted basis increased 6% to 207.1 million shares for the first quarter, compared 195.0 million for the year-earlier period.

"We are obviously very pleased with the improvement in our operating results, cash flow and net income during the quarter," said J. Russell Porter, Gastar's Chairman, President and CEO. "We have spent quite a few years building a company with quality assets and exciting growth opportunities.

"The improvement in production and operating costs per unit reflect the positive results of our drilling in East Texas. We are working to build on these positive results and expect that our production profile in East Texas will likely continue to be somewhat choppy but overall trending upward for the balance of the year.

"In Australia, we are making excellent progress towards identifying additional reserves through an expanded pilot production program and continue to look forward to first commercial sales by year-end," Porter said.

Operations Review and Update

In East Texas, as of March 31, 2008, we had successfully completed 14 out of 15 deep Bossier wells and four out of four Knowles Limestone wells. Net production from the Hilltop area averaged 20.9 MMcf per day, up approximately 40% from 15.0 MMcf per day for the fourth quarter of 2007 and up approximately 121% from 9.5 MMcf per day for the three months ended March 31, 2007. Capital expenditures for the 2008 quarter in East Texas were approximately $12 million.

We are currently drilling the Lone Oak Ranch #6 well (LOR #6) to target middle Bossier sands. It is being drilled using a slim-hole casing design at an estimated cost of $8.0 million to drill and complete the well and should reach our targeted depth in early June. We are also side-tracking the LOR #4 well horizontal section in order to re-complete the well using a strata-pack system that will allow for multiple acid fracture stimulations of the Knowles Limestone pay zones. The LOR #4 was originally completed as an open-hole well with no acid fracture stimulation. We are also currently completing the Holmes #1 well, an immediate offset to the successful F-K #1 well, in one deep Bossier sand. Earlier we announced plans to complete the well in two Bossier sands and co-mingle the production, but further core analysis indicated that the deeper of the sands would very likely be marginal to un-economic to complete. The well went on production on May 10 and is currently producing approximately 4.0 MMcf per day.

For the balance of 2008, Gastar anticipates a two-rig drilling program in East Texas, with one rig dedicated to drilling Bossier wells and the second rig dedicated to drilling horizontal Knowles Limestone wells.

In the Powder River Basin, during the first quarter we participated in the drilling of four gross (2.0 net) coalbed methane wells, with our share of capital expenditures totaling approximately $400,000. Our average net production from our properties in the basin was approximately 5.6 MMcf per day, up from 4.5 MMcf per day for the first quarter 2007. We expect to continue to participate in the planned recompletion and drilling program in 2008.

In New South Wales, Australia, Gastar and our joint venture partner on the PEL 238 concession recently successfully completed the Dewhurst #2, the first test corehole in a 20-well exploration and appraisal corehole drilling program. The results of the Dewhurst #2 confirmed the presence of a thick Bohena coal seam developed to the south and east of the Bibblewindi pilot production area. The Dewhurst #2 encountered approximately 39 meters of coal within the Black Jack and Maules Creek coal formations including approximately 18.2 meters in the targeted Bohena seam, of which 14.7 meters was found in a single coal zone. Further testing has confirmed a high methane content within the targeted Bohena coal seam. We have commenced drilling the second test corehole of the 2008 gas reserves upgrade program, the Dewhurst #3, which is located approximately 2.2 miles east of the Dewhurst #2.

Additionally, progress is being made to finalize all permits necessary to build the 32 kilometer gathering system from our production pilot areas to the Wilga Park power station, with first commercial sales still expected by year-end 2008.
