NEWS RELEASE
Summer Drilling Program - Pt-123 Well
Loon Energy Inc. (“Loon”) (TSX-V:LEY) announces
that Troy Ikoda Limited (“Troy Ikoda”) have
submitted the first part of their report on the Petisovci-Globoki
(“Pg”) gas reservoirs (the “Report”)
which underlie Loon lands in northeastern Slovenia. Troy Ikoda
is an independent UK engineering and consulting firm who have
been retained by Grove Energy Limited (TSX-V:GRV) to undertake
a technical review of the Pg reservoir to determine Gas Initially
In Place (“GIIP”) as well as to review operational
issues associated with the stimulation applied to earlier
wells. The second part of the Report, which will evaluate
potential frac design and stimulation alternatives, will be
completed after the drilling of the Grove D-14 well.
Grove is a joint venture partner of Loon in the development
of the deeper gas horizons contained in the Pg zone.
The Pg reservoir (Middle Miocene) underlies the Upper Miocene
Petisovci-Dolina oil field in eastern Slovenia. The
Pg reservoir was first discovered in 1960. A total of
nine wells (Pg-1 to Pg-9) were drilled through the zone with
five of them, drilled in the 1980’s, having the benefit
of modern logs. The wells produced sweet natural gas
(91% methane, 2.5% C02) with some condensate. Cumulative
gas production from earlier wells totalled approximately 9
Bcf of which more than 8.5 Bcf was contributed by two wells
from a single zone.
The Pg reservoir section consists of approximately 1,100 metres
of interbedded sand, siltstone and shales interpreted to be
deposited in a turbiditic environment. The formation
requires hydraulic fracture stimulation to enhance flow rates.
Limited stimulations were attempted in the existing
wells prior to 1990 and post-stimulation performance was variable.
In a number of instances, the stimulation work has proven
the success of hydraulic fracturing with pre- to post-fracture
treatment rate enhancements up to ten-fold being achieved.
Wells Pg-1 and Pg-5 responded positively to fracture
treatment and between them produced more than 8.5 Bcf of natural
gas from the E-1 reservoir zone, lying at a depth of some
2,700 metres.
The Report splits the GIIP estimates into two tables.
Table 1 indicates GIIP estimates for zones which were tested
in earlier wells (Zones D and E) and Table 2 indicates estimates
for untested zones.

Over the past 15 years there has been significant
improvement in frac design, fluid technology, equipment and
implementation procedures. The analysis undertaken by
Troy Ikoda and outlined in the Report has identified numerous
gas-bearing zones which may be capable of production.
Enhanced flow rates from both existing and future wells may
be achievable using modern hydraulic fracturing techniques
and multiple zone stimulations.
Actual recovery of natural gas from the
Pg will be dependent upon the success of any stimulation undertaken.
No quantification of potential recoverable gas reserves in
the Pg has been provided in the Report or estimated by Loon.
Loon will have a 10.5% carried working interest in all
gas ultimately produced from the Pg.
The Grove D-14 well will be drilled in late August and early
September at no cost to Loon to evaluate the potential of
the Pg zone underlying the Petisovci and Dolina fields.
The fields lie on a large anticlinal structure approximately
18 km in length and up to 2 km in width which continues east
into Hungary. Approximately 40% of the structure, all
of which is included in the Loon-Grove joint venture area,
is in Slovenia. The Troy Ikoda estimates of GIIP for
the Pg relate only to the Slovenian portion of the structure,
all of which is subject to the Loon/Grove arrangement.
The Lovaszi oil field, on the Hungarian side of the structure,
has produced 50 million barrels of oil and 230 Bcf of gas.
The Petisovsci-Dolina field area has produced 5.6 million
barrels of oil and 34.3 Bcf of gas, less than 15% of the volumes
produced at Lovaszi. All of the oil production
and 75% of the gas production coming from the Slovenian side
of the structure was produced from zones above 2,000 metres
which are not subject to the joint venture arrangement with
Grove. The Company believes that significantly more
oil and gas can be produced from these shallower zones underlying
the Slovenian part of the structure. The Pt-123 well,
which will evaluate the potential of these shallower zones,
will spud in late July.
Loon is focused on exploration and development projects in
Slovenia and other countries in south-central Europe.
Slovenia is bounded by Croatia (south), Hungary (east), Austria
(north) and Italy (west). The principal project area
is located in eastern Slovenia near to the borders with Hungary
and Croatia approximately 210 kilometres south of Vienna,
Austria and 180 kilometres northeast of Ljubljana, the capital
of Slovenia. Slovenia joined NATO in April, 2004 and
the European Union (“EU”) on May 1 of this year.
