CALGARY, Sept. 14, 2011 /CNW/ - Gran Tierra Energy Inc. ("Gran Tierra Energy") (NYSE Amex: GTE) (TSX:
GTE), a company focused on oil exploration and production in South America,
today announced results of two exploration wells.
Garibay Block, Llanos Basin
Initial testing of the Melero-1 exploration well, located on the Garibay
Block in the Llanos Basin, has been completed. The well spud on June
22, 2011, and reached total measured depth at 9,748 feet or 9,561 feet
true vertical depth on July 16, 2011. Four drill stem tests were run
and average production of 922 barrels of oil per day of 16.8 degrees
API gravity with a 0.3% water cut was obtained from an interpreted 16
feet of net pay in the Upper Mirador reservoir. This well is currently
suspended for long-term testing.
In addition, the Jilguero-2 appraisal well on the Garibay Block was spud
on September 10, 2011. This well is located at the Jilguero oil
discovery made by the joint venture between a subsidiary of Gran Tierra
Energy and CEPSA Colombia S.A., a wholly-owned subsidiary of Compania
Espanola de Petroleos, S.A. ("CEPSA").
The joint venture is also in the process of acquiring an additional 80
square kilometers of 3D seismic data to assist in the evaluation of
other structures identified on 2D seismic on the block.
Gran Tierra Energy, through an indirect wholly owned subsidiary, holds a
50% working interest in the Garibay Block while, CEPSA holds the
remaining 50% and is the operator of the property.
Rinconada Norte Block, Neuquen Basin
The first of three exploration wells to be drilled in the Rinconada
Norte Block located in the Neuquen Basin of Argentina has made a new
discovery of oil, testing 1,023 barrels of oil equivalent per day.
The RN x-1004 well flowed a total combined test rate of approximately
944 barrels of oil per day and approximately 0.5 million cubic feet per
day of natural gas for a total of approximately 1,023 barrels of oil
equivalent per day from two intervals tested separately in the Precuyo
formation. This well also flowed 43 barrels of water per day or a 4%
Test and electric log data from the depths of the zones tested (3,222 -
3,255 feet and 3,353 - 3,386 feet) suggests a gross oil column
thickness of approximately 197 feet. The oil is 29.6 degrees API
Having completed the first of the three exploratory wells, the service
rig is set to move to complete and test the next two wells, which have
already been drilled and cased.
Americas Petrogas Argentina S.A., the wholly-owned subsidiary of America
Petrogas Inc., is the operator of the Rinconada Norte Block with a 65%
working interest upon completing certain work program obligations,
while Gran Tierra Energy, through an indirect wholly owned subsidiary
holds a 35% working interest.
"Gran Tierra is pleased these oil discoveries will contribute to our
existing base of reserves and production in Colombia and Argentina,
while we prepare for additional exploration drilling in these countries
and in Brazil in 2011", said Dana Coffield, President and CEO of Gran

The use of the words "expected", "planning" and "will" identify
forward-looking statements. In particular, but without limiting the
foregoing, this news release contains forward-looking statements
regarding Gran Tierra Energy's planned and expected presence in
Colombia and Argentina, planned acquisition of 3D seismic data, and the
timing of drilling, testing and spudding the exploration wells.
The forward-looking statements contained in this news release reflect
several material factors and expectations and assumptions of Gran
Tierra Energy including, without limitation, assumptions relating to
production rates at Melero-1 and the RN x - 1004 wells. Gran Tierra
Energy believes the material factors, expectations and assumptions
reflected in the forward-looking statements are reasonable at this time
but no assurance can be given that these factors, expectations and
assumptions will prove to be correct.
The forward-looking statements contained in this news release are
subject to risks, uncertainties and other factors that could cause
actual results or outcomes to differ materially from those contemplated
by the forward-looking statements, including, among others; unexpected
technical difficulties and operational difficulties may occur, or the
obtaining of environmental permits may be delayed, which could impact
or delay the drilling of the exploration wells; and geographic,
political and weather conditions can impede testing, which could impact
or delay the commencement of drilling, testing and spudding exploration
wells; and the risk that current global economic and credit market
conditions may impact oil prices and oil consumption more than Gran
Tierra Energy currently predicts, which could cause Gran Tierra Energy
to not realize the benefit that it expects from the two oil discoveries
in Colombia and Argentina described in this press release. Further
