Gastar Exploration Announces Results of Operations for the Quarter Ended March 31, 2007

HOUSTON, May 15, 2007 (BUSINESS WIRE) -- Gastar Exploration Ltd. (AMEX:GST) (TSX:YGA) reported a net loss attributable to common shares for the three months ended March 31, 2007 of $11.0 million, or $0.06 per basic and diluted common share, compared to a net loss of $42.9 million, or $0.26 per basic and diluted common share, for the three months ended March 31, 2006. The first quarter 2007 loss included a litigation settlement expense accrual of $5.0 million. There was no litigation settlement expense for the three months ended March 31, 2006. The first quarter 2006 loss included an impairment of natural gas and oil properties of $37.3 million. There was no impairment of natural gas and oil properties for the three months ended March 31, 2007. Total revenues for the three months ended March 31, 2007 were $7.5 million, a 13% increase over revenues of $6.6 million for the 2006 comparable period. The increase in revenues was primarily attributable to a 28% increase in production resulting from the commencement of production of natural gas from new wells in East Texas in 2007. The increase in production was partially offset by a 12% decrease in natural gas prices. Average daily production for the three months ended March 31, 2007 was 14.1 million cubic feet of natural gas equivalents per day ("MMcfed"), an increase of 27% compared to 11.1 MMcfed for the three months ended March 31, 2006 and a 3% increase over production for the fourth quarter of 2006 of 13.7 MMcfed. Net cash flow provided by operating activities for the three months ended March 31, 2007 was $281,000, compared to a deficit of $2.7 million for the comparable period in 2006.

J. Russell Porter, Gastar's President and Chief Executive Officer, made the following comment, "Gastar continues to grow production volumes as we bring on new wells in the deep Bossier play. Revenues increased despite lower average natural gas and oil prices, compared to the first quarter of 2006. We currently are nearing total depth of two additional wells that are expected, along with the Wagner #1 well, to impact third quarter production volumes. Following the closing of the sale of a portion of our undeveloped leasehold interests in East Texas, we are positioned to increase our deep Bossier drilling program following the interpretation of new 3-D seismic data. We also anticipate an increase in activities on our PEL 238 coal bed methane property during the second half of 2007."
