Bretaña-1WD Recovers Oil in Transition Zone, Increases Recoverable Oil
CALGARY, June 2, 2014 /CNW/ - Gran Tierra Energy Inc. ("Gran Tierra Energy") (NYSE MKT: GTE, TSX: GTE), a company focused on oil exploration and production in South America,
today provided an operations update for its 2014 work program.
"Gran Tierra Energy's 2014 drilling campaign is well under way, and
initial well test results are providing valuable insights for the
Bretaña and Moqueta oil fields in Peru and Colombia," said Dana
Coffield, President and Chief Executive Officer of Gran Tierra Energy.
"Testing of the newly-drilled Bretaña water disposal well indicates
moveable oil saturation in the transition zone where no reserves had
been assigned previously, with potential for adding substantial
additional recoverable resources in the field. Completion of the well
also keeps us on track to initiate the Long Term Test in the fourth
quarter of this year. The Zapotero-1 well was drilled approximately
2,000 feet lower than the lowest known oil on the Moqueta structure.
The Zapotero-1 well tested three zones that resulted in produced water.
We are currently investigating if the Zapotero-1 well can be converted
to a water injection well to maintain reservoir pressure at the Moqueta
field to enhance production in the field. This well result also assists
in planning the target depth for the Corunta exploration well that will
be drilled on the opposite flank of Moqueta later this year. The well
will target an intermediate depth, below the lowest known oil in the
Moqueta field and shallower than the reservoirs in Zapotero-1, to
further define the oil-water contact location and ultimate size of the
Moqueta oil accumulation," concluded Coffield.
Block 95, Bretaña Field (Gran Tierra Energy 100% Working Interest ("WI")
The Bretaña-1WD water disposal well was spud on April 10, 2014, and
reached a total true vertical depth of 10,038 feet on May 17, 2014.
Modular Dynamics Testing was conducted to investigate a thick oil-water
transition zone where reserves have not previously been assigned. Oil
was recovered from the transition zone with preliminary analysis
suggesting approximately two meters of additional pay for the field,
which should have a positive impact on recoverable oil resource in the
Bretaña field due to the large aerial extent of the reservoir in the
structure at that depth.
Chaza Block, Putumayo Basin (100% WI and Operator)
The Zapotero-1 exploration well reached a total true vertical depth of
7,549 feet. Production testing of the well indicates the presence of
water in the Villeta T and U Sandstones, and in the Caballos
formation. Gran Tierra Energy is now investigating a possible pressure
communication between Zapotero-1 and Moqueta-3, and the potential to
convert Zapotero-1 into a water injector to enhance production from the
Moqueta-13 development well was spud on May 25, 2014 and is drilling in
a southeast direction from the Moqueta-1 well pad. Moqueta-13 is
intended to add to the production of the Moqueta field.

The use of the words "will", "should", "planning", "intended" and
"potential" and derivations thereof and similar terms identify
forward-looking statements. In particular, but without limiting the
foregoing, this news release contains forward-looking statements
regarding Gran Tierra Energy's exploration program, additional
recoverable resource potential in Peru, additional production in
Colombia and expectations regarding drilling locations and depth,
testing, well conversions and expected timing of activities and
results. Statements relating to "resources" are forward looking
statements as they involve the implied assessment, based on estimates
and assumptions that the resources described exist in the quantities
predicted or estimated and can be profitably produced in the future.
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
log evaluations; that Gran Tierra Energy will continue to conduct its
operations in a manner consistent with past operations; the accuracy of
resource estimates; the accuracy of testing and production results and
seismic data; the effects of certain drilling techniques; cost and
price estimates; and the general continuance of current or, where
applicable, assumed operational, regulatory and industry conditions.
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: test
results provide only an indication of resource amounts and are not
conclusive as to actual resource amounts, which may be substantially
different than indicated by the test results; Gran Tierra Energy's
operations are located in South America where unexpected problems can
arise due to guerilla activity and labour disruptions; unexpected
technical difficulties and operational difficulties may occur, which
could impact or delay the completion or continuation of drilling;
geographic, political and weather conditions can interrupt drilling,
which could impact or delay the commencement or continuation of
drilling; 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 change its current drilling, production and testing plans; and
production data should be considered preliminary until a full well test
interpretation has been done. Further information on potential factors
that could affect Gran Tierra Energy are included in risks detailed
from time to time in Gran Tierra Energy's Securities and Exchange
Commission filings, including, without limitation, under the caption
