REC-T-142 Block (Gran Tierra Energy 70% WI & Operator, Alvorada 30% WI)
Drilling of the first horizontal sidetrack well, currently planned to be drilled from the 1-GTE-01-BA pilot hole, has been delayed to June, 2012 due to rig availability. This will be the first of three horizontal sidetrack wells that Gran Tierra Energy expects to be drilled to test the productivity of the light oil sandstone reservoir targets in the Recôncavo Basin.
First quarter production and sales have been impacted by approximately 26 days of oil delivery restrictions due to three separate Ecopetrol-operated Oleoducto Transandino (" OTA") pipeline disruptions in Colombia, the latest of which occurred on March 13, 2012. Gran Tierra Energy continued production at a reduced rate while the OTA pipeline was down, selling a portion of its crude through trucking and storing excess crude. The pipeline has been repaired and was back in service on March 24, 2012. Gran Tierra Energy's current production is approximately 19,200 barrels of oil equivalent per day (" BOEPD").Also, as a result of entering into new crude oil sales and transportation agreements with Ecopetrol as of February 1, 2012, which changed the sales point of produced oil from Orito to Tumaco, Gran Tierra Energy's reported crude oil inventory will increase representing ownership of oil in the OTA and associated Ecopetrol owned facilities. This change in sales point and the increase in crude oil inventory will have a corresponding one-time reduction in oil sales of approximately 1,600 BOEPD net after royalty (" NAR") to be reported for the quarter. As a result of the OTA pipeline disruptions and the new crude oil sales and transportation agreements, sales for all Gran Tierra Energy properties are expected to average approximately 16,000 BOEPD NAR, from January 1, 2012 to March 31, 2012.
