Gran Tierra announces oil discovery in Peru Gran Tierra Energy provided updates for its exploration drilling in Peru and appraisal drilling in Colombia. "Initial drilling results from the Breta a Norte 95-2-1XD exploration well in Peru indicate oil-saturated reservoir with a gross oil column of 99 feet that was encountered approximately 48 feet higher than oil discovered at Breta a-1 approximately four kilometers away. Three cores encompassing 90 percent of the oil-bearing reservoir section were successfully acquired. As previously announced, this prospect contains substantial contingent resource potential, so these initial results are extremely exciting," said Dana Coffield, President and Chief Executive Officer of Gran Tierra Energy. "In addition, we have successfully tested the Moqueta-8 appraisal well in Colombia and are now drilling the Moqueta-9 appraisal well, as we continue to evaluate the full potential of this growing oil discovery," concluded Coffield.
