            Gastar Exploration Reports Third Quarter 2007
                  Financial and Operational Results

    HOUSTON--(BUSINESS WIRE)--Nov. 7, 2007--Gastar Exploration Ltd.
(AMEX:GST) (TSX:YGA) today reported financial and operational results
for the three and nine months ended September 30, 2007.

    Net loss for the third quarter of 2007 was $5.5 million, or $0.03
per share, compared to a net loss of $7.7 million, or $0.05 per share,
for the third quarter of 2006. The third quarter 2006 net loss
included a charge for litigation settlement expense of $465,000.

    Revenues for the third quarter of 2007 increased 46% to
approximately $9.8 million, compared to revenues of $6.7 million for
the comparable period in 2006. The increase in revenue was primarily
due to increased natural gas production from new wells in East Texas,
partially offset by a 10% decrease in natural gas prices, mainly
related to Wyoming production.

    Net cash flows provided by operating activities for the three
months ended September 30, 2007 were $5.5 million, compared to a cash
loss of $2.3 million for the comparable period in 2006.

    Weighted average shares of common stock outstanding on a basic and
diluted basis increased 23% to 207.1 million shares for the third
quarter of fiscal 2007 compared to the year-earlier period.

    Average daily production for the third quarter of 2007 was 22.7
million cubic feet of natural gas equivalent per day (MMcfe/d) -- an
increase of 66%, compared to 13.7 MMcfe/d for the third quarter of
2006 -- and a 50% increase over production levels of 15.1 MMcfe/d for
the second quarter of 2007, due to three East Texas wells being
brought on at high initial production rates. The average realized
price for natural gas in the third quarter of 2007 was $4.65 per Mcf
compared to $5.14 per Mcf in the third quarter of 2006.

    Lease operating expense (LOE) was $1.7 million for both the third
quarter of 2007 and 2006. LOE per Mcfe decreased 40% to $0.81 per Mcfe
during the third quarter of 2007 from $1.35 per Mcfe for the
comparable period in 2006 and decreased 26% from $1.10 per Mcfe for
the second quarter of 2007. The decrease in LOE per Mcfe was primarily
due to higher production volumes combined with lower ad valorem taxes
and lower fixed costs associated with natural gas treatment plants in
East Texas.

    J. Russell Porter, Gastar's Chairman, President and CEO, stated,
"We are making excellent progress toward further delineating the value
of our East Texas and Australian assets. In East Texas the accumulated
drilling and production data is helping us to improve drilling
results, and we are now beginning to utilize our new 3-D seismic data
to better identify future drilling locations.

    "One of our best Deep Bossier wells to date, the Donelson #3, is
maintaining a solid production rate at approximately 13.7 MMcf/d. We
are currently drilling an offset well based on the new 3-D data, the
Wildman Trust #3, which should reach the Deep Bossier formation in
mid-December. Due to the success of our first horizontal Knowles
Limestone well, the Lone Oak Ranch ("LOR") #4, we have secured a
second rig which is currently drilling the LOR #3, another horizontal
well targeting the Knowles Limestone formation that is expected to
reach total depth in early December.

    "In the fourth quarter we expect production levels will be
slightly lower than what we averaged in the third quarter due to the
natural decline in peak production from the new East Texas wells
brought on in July and August. In addition, Wyoming production was
curtailed during October due to low natural gas prices being realized
in the area. We should see improvement in production volumes compared
to the third quarter in the first quarter of 2008 as we complete the
Wildman Trust #3 and the LOR #3, assuming these come on production as
expected," added Porter.

    "In Australia, we received the initial proved and probable (2P)
gas reserve certification from our independent engineering firm,
Netherland Sewell & Associates, for PEL 238 in New South Wales. A
total 59 Bcf were certified, including 21 Bcf of gross proved (1P)
reserves (6.6 Bcf net), although the evaluated acreage covers less
than 1 percent of the acreage. These reserve estimates are made under
the Society of Petroleum Engineers standards, and none of these yet
meets the definition of proved reserves under SEC guidelines,
primarily due to the early status of negotiations for contracts for
infrastructure and gas sales. This is just the first step toward
defining the value of our extensive acreage position in New South
Wales. Our ongoing nine-well pilot program is continuing to perform
well, and we are currently drilling a six-well corehole program
designed to increase 2P reserve certification by mid-2008."

    Nine Month Results:

    For the nine months ended September 30, 2007, Gastar reported a
net loss of $12.1 million, or $0.06 per share, compared to a net loss
of $57.3 million, or $0.34 per share, for the nine months ended
September 30, 2006. Results for the nine months of 2007 included a
gain on the sale of unproved natural gas and oil properties of $38.9
million, a non-cash full cost ceiling impairment of natural gas and
oil properties of $28.5 million and a $5.0 million litigation
settlement expense. Results for the first nine months of 2006 included
a non-cash full cost ceiling impairment of natural gas and oil
properties of $37.3 million and a charge for litigation settlement
expense of $1.7 million. Excluding the effect of these items in both
years, Gastar would have incurred a loss of $17.5 million, or $0.09
per share, for the nine months of 2007, compared to a loss of $18.4
million, or $0.11 per diluted share, for the same period in 2006.

    Revenues for the nine months ended September 30, 2007 were $25.2
million, compared to revenues of $20.0 million for the comparable
period in 2006. Average daily production for the nine months of 2007
was 17.3 MMcfe/d, up 37% from 12.7 MMcfe/d for the nine months of
2006.

    Net cash flows provided by operating activities for the nine
months ended September 30, 2007 were $11.2 million, (excluding $38.9
million of gain on sale and a $5.0 million litigation settlement
accrual) compared to $415,000 for the comparable period in 2006
(including the payment of $1.7 million of litigation settlement
expense).

uncertainties that may cause actual future activities and results to

failure, casing collapse, unusual or unexpected formation pressures,
environmental hazards, and other operating and production risks
inherent in the natural gas and oil drilling and production
activities, which may temporarily or permanently reduce production or
cause initial production or test results to not be indicative of
future well performance or delay the timing of sales or completion of
drilling operations, risks with respect to natural gas and oil prices,
a material decline in which could cause the Company to delay or
suspend planned drilling operations or reduce production levels, and
risks relating to the availability of capital to fund drilling
operations that can be adversely affected by adverse drilling results,
production declines and declines in natural gas and oil prices and
other risk factors described in the Company's Annual Report on Form
10-K, as filed on March 27, 2007 with the SEC at www.sec.gov and on

    The SEC has generally permitted oil and gas companies, in their
filings with the SEC, to disclose only proved reserves that, under SEC
definitions and guidelines, a company has demonstrated by actual
production or conclusive formation tests to be economically and
legally producible under existing economic and operating conditions.
We use the terms in this announcement such as "2P" or "probable"
reserves, or other descriptions of volumes of hydrocarbons that the
SEC's guidelines would prohibit us from including in our filings with
the SEC. We also have included in this announcement information
concerning reserves attributed to our Australian coal bed methane
pilot program that are categorized as "proved" under the definitions
and guidelines set by the Society of Petroleum Engineers that would
not be so categorized under SEC definitions and guidelines. All of
these volumes and estimates are by their nature more speculative than
estimates of proved reserves under SEC definitions and guidelines and
accordingly are subject to substantially greater risk of being
actually realized by us.
