Gran Tierra Energy has completed drilling and testing the Proa-2 appraisal well, the second well in the Proa oil field. The successful well encountered approximately 102 feet (31 meters) of net pay in two Palmar Largo intervals. Production tests were performed on the two intervals independently, resulting in combined natural flow rates of 6,300 barrels of oil per day ("bopd") gross of 46 degree API oil with no water cut. The well is expected to be on production in April, 2012, initially at approximately 2,000 bopd gross to further analyze reservoir performance while additional transportation capacity is evaluated.
