Gran Tierra Energy Announces $367 Million Capital Program for 2012

Ten exploration wells and seventeen development wells in Colombia, Brazil, Peru and Argentina

CALGARY, Alberta, December 16, 2011, 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 a 2012 capital spending program of $367 million for its exploration and production development operations in Colombia, Brazil, Peru and Argentina. The capital spending program allocates $246 million for drilling, $39 million for facilities, equipment and pipelines, including $2 million associated with corporate activities, and $82 million for seismic activities.  The budget contemplates the drilling of 11 wells in Colombia, 13wells in Argentina, two wells in Brazil and one well in Peru. The approved 2012 capital spending program also includes funds for 1,154 km of 2D and 427km2 of 3D seismic acquisition programs in Colombia, Peru, Argentina and Brazil, primarily in preparation for additional exploration and production drilling operations in 2013 and beyond.

Excluding potential exploration success, production in 2012 is expected to range between 26,000 to 27,000BOEPD gross, or 20,000 to 21,000 BOEPD NAR. Approximately 95% of this production consists of light oil, with the balance consisting of natural gas.

Gran Tierra Energy had $226 million in cash and equivalents at the end of the third quarter 2011 and has no debt. The 2012 work program and budget is expected to be funded primarily from cash flows from operations, with the balance from cash on hand as necessary, at current oil prices.

“Gran Tierra Energy remains committed to continue executing its strategy through 2012, a strategy that has consistently grown land, reserves and production year over year for the last six years. Our focus on execution sees us entering 2012 with a robust exploration portfolio and a balanced mix of development drilling to maintain our base of reserves and production, and exploration drilling to grow that base.” said Dana Coffield, President and Chief Executive Officer of Gran Tierra Energy. “This singular focus on execution has allowed us to not only grow year over year, but allowed us to do so with an exceptionally strong balance sheet. As before, we are entering another year fully funded from cash flow and cash on hand to execute our capital program, in spite of the current tumultuous global economic environment. Gran Tierra Energy, again, is positioned for continued growth,” concluded Coffield.


Gran Tierra Energy’s land position in Colombia encompasses approximately 3.5 million gross acres or 3.1 million net acres on 21 blocks in the Putumayo, Llanos, Cauca and Lower Magdalena Basins. The Colombia capital budget for 2012 is $182 million and is expected to include drilling four gross exploration wells and seven gross development wells. Gran Tierra Energy’s oil exploration drilling program will target prospects in the Putumayo and Llanos basins, while development drilling will focus on the Moqueta, Costayaco and Brillante field developments, with total drilling expenditures of $104 million. Facilities work, including continued electrification of the Costayaco and Moqueta fields, water injection facilities and a production battery at the Jilguero oil discovery is expected to be $27 million. Geological and geophysical (“G&G“) work consisting of 427 kmof 3D seismic and 201 km of 2D seismic, along with other costs, is expected to be $51 million. G&G work is planned for the Cauca-6, Cauca-7, Moqueta, Garibay, Piedmonte Norte, Piedmonte Sur, Putumayo-1 and Putumayo-10 Blocks to mature leads and prospects for drilling in 2013 and beyond. 

In addition to the budgeted program, there is a large portfolio of contingent drilling opportunities, some of which are expected to mature into firm drilling programs in 2012, subject to timing of permit approvals.

Seismic acquisition is continuing on the Chaza block to further delineate the Moqueta field and to evaluate new prospects along trend with Moqueta.

In addition to two development wells planned at the Moqueta field, Gran Tierra Energy continues to see positive responses from its water injection program at the Costayaco field and intends on drilling two additional water injector wells along with two production wells.
