      Gastar Updates Recent East Texas Bossier Well Completions

    HOUSTON--(BUSINESS WIRE)--Aug. 7, 2007--Gastar Exploration Ltd.
(AMEX:GST) (TSX:YGA) announced today that following changes to its gas
gathering system to allow gas gathering at higher field pressures, the
Donelson #3 well is flowing at a current gross sales rate of
approximately 20 MMcfd and 8,300 psi flowing casing pressure from a
single Bossier zone completion. The Wagner #1 well is flowing from a
single Bossier zone at a current gross sales rate of approximately 3.9
MMcfd. Gastar has a 67% working interest and an approximate 50.0% net
revenue interest in the Donelson #3 well and a 50% working interest
and an approximate 37.5% net revenue interest in the Wagner #1 well.

    The John Parker #3, a vertical well drilled to the Knowles
Limestone formation, is producing at a current gross sales rate of
approximately 2.0 MMcfd prior to stimulation. In an effort to further
enhance production, the John Parker #3 well is scheduled for an acid
fracture stimulation during the week of August 13th, following
operational delays caused by area flooding. Gastar currently is
drilling the Lone Oak Ranch #4, a horizontal Knowles Limestone well,
which is expected to reach total depth in approximately three weeks.

    J. Russell Porter, Gastar's President & CEO, stated, "We are
pleased that the Donelson #3 well is producing at such an attractive
rate from just one Bossier zone completion, and at this time, we do
not anticipate completing any additional zones in the near-term. We
are moving forward with our evaluation of the Wagner #1 well, with
plans to add additional Bossier completions at a later date."

    Gastar Exploration Ltd. is an exploration and production company
focused on finding and developing natural gas assets in North America
and Australia. The Company pursues a strategy combining select higher
risk, deep natural gas exploration prospects with low-risk coal bed
methane (CBM) development. The Company owns and operates exploration
and development acreage in the deep Bossier gas play of East Texas.
Gastar's CBM activities are conducted within the Powder River Basin of
Wyoming and upon the approximate 3.0 million gross acres controlled by

    Safe Harbor Statement and Disclaimer:

    This Press Release includes "forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933 and Section
21E of the Securities Act of 1934. A statement identified by the words
"expects", "projects", "plans", and certain of the other foregoing
statements may be deemed forward-looking statements. Although Gastar
believes that the expectations reflected in such forward-looking
statements are reasonable, these statements involve risks and
uncertainties that may cause actual future activities and results to
be materially different from those suggested or described in this
press release. These include risks inherent in the drilling of natural
gas and oil wells, including risks of fire, explosion, blowout, pipe
failure, casing collapse, unusual or unexpected formation pressures,
environmental hazards, and other operating and production risks
inherent in 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 oil and natural gas 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 United States Securities and Exchange
Commission at www.sec.gov and on the System for Electronic Document
Analysis and Retrieval (SEDAR) at www.sedar.com.
