Gran Tierra Energy Announces 2011 Year-End Reserves
Reservoir Performance at Costayaco, Moqueta Appraisal Program, and Asset Acquisitions Result in Another Record Year of Reserves and Production
CALGARY, Feb. 6, 2012 /CNW/ - Gran Tierra Energy Inc. (NYSE Amex: GTE; TSX: GTE) ("Gran Tierra Energy"), a company focused on oil exploration and production in South America, today announced the results of an independent reserve evaluation of the company's reserves by GLJ Petroleum Consultants Ltd. ("GLJ") effective December 31, 2011.
Year-end 2011 Highlights net after royalty ("NAR"), calculated in accordance with United States Securities and Exchange Commission ("SEC") rules (comparisons are to 2010 year end amounts):
- Total Proved ("1P") reserves increased 43% to approximately 34.0 million barrels of oil equivalent (approximately 90% light and medium oil and liquids);
- Total Proved plus Probable ("2P") reserves increased 56% to approximately 48.8 million barrels of oil equivalent (approximately 85% light and medium oil and liquids);
- Total Proved plus Probable plus Possible ("3P") reserves increased 57% to approximately 85.8 million barrels of oil equivalent (approximately 69% light and medium oil and liquids);
- Reservoir performance expectations were exceeded at the Costayaco field in Colombia. Costayaco 1P reserves changed to 16.4 million barrels of oil at year-end 2011, from 17.7 million barrels of oil at year-end 2010 despite total production of 4.5 million barrels of oil NAR at the Costayaco field in 2011;
- Appraisal drilling in 2011 within the area of mapped possible reserves in the Moqueta field in Colombia resulted in 1P reserves increasing 329% to approximately 5.1 million barrels of oil, 2P reserves increasing 157% to 7.7 million barrels of oil and 3P reserves increasing 2% to 9.9 million barrels of oil. The limits of the field have not yet been defined;
- Gran Tierra Energy produced approximately 8.3 million barrels of company interest oil before royalties and 1,634 million cubic feet of company interest gas before royalties in 2011;
- Based on Gran Tierra Energy's 2011 year end SEC company interest reserves and Gran Tierra Energy's 2011 average working interest production, Gran Tierra Energy's 1P, 2P, and 3P reserves life indices are 5.1 years, 7.2 years, and 12.4 years respectively.
- Annual production for 2011 averaged approximately 23,400 company interest barrels of oil equivalent per day ("BOEPD") before royalties, or 17,400 BOEPD NAR, an increase of approximately 21% versus 14,440 BOEPD NAR in 2010. Production in the fourth quarter of 2011 averaged approximately 18,600 BOEPD NAR. Production in December 2011 has averaged approximately 18,400 BOEPD NAR.
All reserves values contained in the 2011 Highlights, provided above, have been calculated using SEC rules. For reserves values calculated in compliance with Canadian National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101") and the Canadian Oil and Gas Evaluation Handbook ("COGEH"), see "Reserves Reported in Accordance with Canadian Reporting Requirements" below in this press release.
"Gran Tierra Energy had another excellent year in growing 1P and 2P reserves and production to record levels from our legacy lands and assets after accounting for production, primarily through superior reservoir management at the Costayaco field and appraisal drilling in the Moqueta field, in addition to modest exploration success during the year. This has been complemented by our acquisition of Petrolifera, which resulted in substantial increase in 3P reserves for future appraisal, and an overall increase in our reserve life indices." said Dana Coffield, President and CEO. "In 2012, we are focused on continuing growing reserves through exploration drilling in Colombia, Peru and Brazil, continued appraisal drilling of new reserves discovered at the Moqueta oil field in Colombia, and growing production through development drilling and reservoir management in existing producing fields in Colombia, Argentina and Brazil. We have exciting exploration drilling programs currently underway in Colombia and Brazil, with more expected to follow this year in all four countries, all anticipated to be funded through available cash and cash flow from operations, allowing the company to remain debt free."

- Reserves were added through development drilling and technical revisions in the Costayaco and Moqueta fields in Colombia.
- Reserves were added through the acquisition of Petrolifera Petroleum Limited ("Petrolifera") in March 2011, which had reserves in Argentina and Colombia and exploration acreage in Peru.
- Reserves were added through the acquisition of 70% working interest on Block 155 in Brazil.
- Partially offsetting reserve additions was 2011 full year production of 8.3 million barrels of company interest oil before royalties and 1,634 million cubic feet of company interest gas before royalties.
- 1P reserves (on an oil equivalent basis NAR) increased 43% largely due to a positive technical adjustment to Costayaco reserves (based on reservoir performance), additional appraisal drillings in Moqueta, and the proved reserves associated with the Petrolifera acquisition and the Brazil Block 155 acquisition.
- 2P reserves (on an oil equivalent basis NAR) increased 56% mainly due to positive technical adjustment to Costayaco reserves (based on reservoir performance), additional appraisal drillings in Moqueta, and the 2P reserves associated with the Petrolifera acquisition and the Brazil Block 155 acquisition.
- 3P reserves (on an oil equivalent basis NAR) increased by 57% or 31.2 million barrels of oil equivalent, largely due to positive technical adjustment to Costayaco reserves (based on reservoir performance), additional appraisal drillings in Moqueta, and the 3P reserves associated with the Petrolifera acquisition and the Brazil Block 155 acquisition.
- Gran Tierra Energy has year-end 2011 NAR 3P gas reserves of approximately 161 billion cubic feet, an increase of 270% from 43 billion cubic feet NAR at year-end 2010 largely associated with the Sierra Nevada Block in Colombia.

- The increase in proved oil reserves is mainly associated with positive technical adjustments in Costayaco reserves (due to reservoir performance), additional development drillings in Costayaco, and the appraisal drilling program in Moqueta Field in Colombia.
- The increase in 2P oil reserves is mainly associated with positive technical adjustments in Costayaco reserves (due to reservoir performance), additional development drillings in Costayaco, and the appraisal drilling program in Moqueta Field in Colombia.
- The decrease in 3P reserves is mainly associated with the total volume of liquid production in 2011.

Cautionary Statements:
Possible reserves are those additional reserves that are less certain to be recovered than Probable reserves. There is a 10% probability that the quantities actually recovered will equal or exceed the sum of Proved plus Probable plus Possible reserves. The estimate of reserves for individual properties may not reflect the same confidence level as estimates of reserves for all properties, due to the effects of aggregation.
A barrel of oil equivalent ("BOE") is calculated using the conversion factor of six thousand cubic feet ("Mcf") of natural gas being equivalent to one barrel of oil. BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf : 1 barrel of oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
