                Preliminary Front End Engineering Design Initiated for Bretaña Norte Field Development in Peru
   CALGARY, April 17, 2013 /PRNewswire/ - 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 updates for its production and exploration drilling in  Colombia, Peru and Brazil.
   "Gran Tierra Energy is pleased to start the year with  record levels of production as we continue to successfully mitigate  transportation disruptions in Colombia," commented Dana Coffield,  President and Chief Executive Officer of Gran Tierra Energy.  "Operationally, we believe the northern boundary of the Moqueta field  has now been successfully delineated with the Moqueta-9 appraisal well.  The balance of this year will focus on increasing water injection for  pressure support and increasing production capacity from the field.   Once permits are in place, we can then direct our attention to  appraising the eastern flank of the Moqueta structure, which remains  undrilled. In Peru, the evaluation of our Bretaña Norte oil discovery  continues, with initial testing of our well extension expected in the  coming month, preliminary field development planning initiated, and long  term testing expected to begin within a year. Our exploration program  in the onshore Recôncavo Basin in Brazil, testing a new play with  horizontal drilling and multi-stage fracture stimulation, is ongoing  with results expected mid-year," concluded Coffield.
   Production
   Average daily consolidated light and medium crude oil and  natural gas production net after royalty (NAR) before inventory  adjustments for the three months ended March 31, 2013, increased 21% to  approximately 21,860 barrels of oil equivalent per day ("BOEPD") NAR  compared with 18,148 BOEPD NAR for the corresponding period in 2012.  Approximately 97% was oil and natural gas liquids. First quarter  production reflects increased production in all countries in which we  are producing with the largest contribution to the increase from the  Costayaco, Moqueta, and Surubi oil discoveries. This increase was  partially offset by approximately 44 days of oil delivery restrictions  due to disruptions in the Ecopetrol-operated Trans-Andean oil pipeline  (the "OTA pipeline") in Colombia. Gran Tierra Energy continued  production while the OTA pipeline was down, selling oil through an  alternative pipeline and trucking and storing excess oil.
   Average daily Colombian production of light and medium  crude oil and natural gas for the three months ended March 31, 2013  increased 18% to approximately 17,850 BOEPD NAR before inventory  adjustments, compared with 15,163 BOEPD NAR before inventory adjustments  for the comparable period in 2012. The production is primarily from the  Costayaco and Moqueta fields in the Chaza Block in which Gran Tierra  Energy has a 100% working interest.
   Additionally, preliminary indications show approximately  139,800 barrels NAR net liquidation of inventory during the quarter.   Inventory volumes will be finalized near the end of April 2013 and, as  such, this figure is subject to change.
   Colombia
   Chaza Block (100% working interest and operator)
   In Colombia, the Moqueta-9D appraisal well was spud on  January 20, 2013 to test the northwest extent of the Moqueta field. It  discovered hydrocarbons in a different fault block, separate from the  main Moqueta oil accumulation. The T-Sandstone tested gas and the  combined Caballos and U-Sandstone formations tested oil and water.   Further isolation testing on the Caballos and U-Sandstone formations  will be conducted to define their hydrocarbon potential. These results,  integrated with seismic and other wells drilled to date, indicate the  well has defined the northern margin of the main Moqueta oil  accumulation.  The down-dip extent of the oil column to the west, south  and east, and the lateral extent of the structure to the east, have not  yet been defined by drilling, with this additional resource potential to  be defined with our ongoing drilling campaign.
   The Moqueta-10 well has begun drilling.  This well will be  used as a water injection well to assist with pressure support in the  Moqueta field to support production growth from existing and future  planned production wells.  This well is being drilled to the far western  flank of the field, and may provide additional information on the  down-dip extent of the oil column in the primary reservoirs in the main  block, which has not yet been determined.  This well will be followed by  Moqueta-11, which is planned to be a production well.
   Peru  
   Block 95 (100% working interest and operator)
   Gran Tierra Energy has initiated drilling of the  horizontal side-track extension of the Bretaña Norte 95-2-1XD oil  discovery well. Casing has been set at the top of the Vivian reservoir,  where very high quality sands with very good oil shows were encountered,  and the drilling of a 500 meter horizontal leg has been initiated.   Upon completion, a short test will be conducted.  Plans are ongoing to  initiate long-term testing from this horizontal well, with production to  be initiated within a year.  In addition, a Preliminary Front End  Engineering Design has been initiated for the Bretaña Norte field  development to support reserves booking, with results expected before  year-end.
   Brazil
   Block 142 (100% working interest and operator)
   Gran Tierra Energy's horizontal multi-stage fracture  stimulation exploration drilling program in the Recôncavo Basin onshore  Brazil is ongoing, with results of the program expected mid-year.

   Forward Looking Statements and Advisories
   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. In addition, given that the value ratio  based on the current price of oil as compared to natural gas is  significantly different from the energy equivalent of six to one,  utilizing a BOE conversion ratio of 6 Mcf: 1 barrel of oil would be  misleading as an indication of value.
