Brazil: Gran Tierra to test Reconcavo oil appraisal wells

Gran Tierra Energy Inc., Calgary, will test and place on production in the third quarter of 2012 two appraisal wells near its Tie field discovery on Block REC-T-155 in the Reconcavo basin in Brazil.

The 3-GTE-03D-BA and 3-GTE-4DPA-BA appraisal wells are 1.2 km north and 0.7 km south, respectively, of the 1-ALV-2-BA oil discovery well. The company submitted a declaration of commerciality to Brazil’s ANP on July 27.

Spudding of the first horizontal sidetrack well, from the 1-GTE-01-BA pilot hole on Block REC-T-142, is expected in the third quarter of 2012. This will be the first of two horizontal sidetracks that the company expects to drill in 2012 to test the productivity of light oil sandstone reservoir targets in the Reconcavo basin. Gran Tierra deferred a third horizontal well into early 2013.
