Gran Tierra Energy Provides South America Drilling Operations Update
Ramiriqui-1 Exploration Well Encounters Oil Shows, Testing to begin in April
CALGARY, Feb. 21, 2012 /PRNewswire/ - Gran Tierra Energy Inc. (NYSE AMEX: GTE; TSX: GTE) ("Gran Tierra Energy"), a company focused on oil and gas exploration and production in South America, today announced a drilling update in the Putumayo and Llanos basins of Colombia, Recôncavo Basin of Brazil, and Noroeste Basin of Argentina.
"Gran Tierra Energy's 2012 drilling campaign is now well underway, with a mix of exploration and development drilling in both Colombia and Brazil in progress, while planning continues for additional drilling through the year in those countries, and in Peru and Argentina," said Dana Coffield , President and CEO of Gran Tierra Energy.
Llanos-22 Block, Llanos Basin (45% working interest, subject to ANH approval; CEPSA 55% working interest and operator)
Drilling operations continue on the Ramiriqui-1 exploration well in the Llanos-22 Block in the foothills of the Llanos Basin. The Mirador formation has been interpreted as oil bearing with up to 130 feet measured depth ("MD") gross thickness based on cuttings and logging while drilling. Casing is being set. Upon completion, drilling is expected to continue to evaluate deeper potential reservoir intervals and is expected to finish in March. Gran Tierra Energy expects testing of the Mirador formation, to confirm fluid content and reservoir productivity, to commence in April 2012.
Chaza Block , Putumayo Basin (100% working interest and operator)
The Pacayaco-1ST1 exploration well reached total true vertical depth of 5,343 feet. Approximately ten feet of oil column in the T-Sandstone was interpreted from cuttings and evaluation of wireline logs. It was determined that the formation did not contain economic quantities of hydrocarbons so the well was plugged and abandoned.
Civil work has been initiated for the Moqueta-7 development well location, with the initiation of drilling anticipated in June 2012.
Azar Block , Putumayo Basin (40% working interest and operator)
Gran Tierra Energy is targeting the same reservoir intervals seen in the Costayaco and Moqueta oil fields with the La Vega Este-1 exploration well. Due to environmental permit delays, we have requested an extension from the ANH for this current phase; this request is still under ANH review. We expect to begin drilling the La Vega Este-1 well in April 2012.
REC-T-142 Block, Recôncavo Basin (Gran Tierra Energy 70% working interest and operator)
Gran Tierra Energy expects drilling of the 1-GTE-6-BA oil exploration well to begin in July 2012. This operation will commence with the drilling of a vertical pilot hole from which core samples will be acquired from the prospective reservoir section. Including the already drilled 1-GTE-01-BA oil exploration well, this is expected to be the second vertical pilot hole drilled on the REC-T-142 Block.
Gran Tierra Energy plans to drill a horizontal sidetrack from each of the pilot holes to test the productivity of the light oil sandstone reservoir target beginning with 1-GTE-1-BA in April 2012.
REC-T-129 Block, Recôncavo Basin (Gran Tierra Energy 70% working interest and operator)
Drilling of the 1-GTE-02-BA oil exploration well began on November 23, 2011. The well reached total depth of approximately 6412 feet measured depth and is suspended while plans are finalized for drilling a horizontal leg in mid 2012.
REC-T-155 Block, Recôncavo Basin (Gran Tierra Energy 70% working interest and operator)
Gran Tierra Energy expects drilling of the 1-GTE-5-BA oil exploration well to begin in June 2012. The well is located in Block REC-T-155 in the Recôncavo Basin. Similar to the vertical pilot holes drilled on the REC-T-142 Block, Gran Tierra Energy expects to drill a horizontal sidetrack well following the pilot hole to test the productivity of the reservoir sandstones.
Gran Tierra Energy completed drilling of the 3-GTE-03-BA development well which is situated 1.2 kilometers north-northeast of the 1-ALV-2-BA discovery well. Oil bearing reservoir intervals in the Sergi and Agua Grande formations were encountered and plans are moving forward to complete the well and place the well on production in May. A second development well located approximately 0.7 kilometers south-southwest of the 1-ALV-2-BA discovery well began drilling on January 8, 2012. The well operations are currently ongoing at 3-GTE-4-BA. No further development wells are planned on this discovery at this time.
Surubi Block, Noroeste Basin (85% working interest and operator)
Drilling continues on the Proa-2 development well in the Proa oil field in the Noroeste Basin of northern Argentina. Gran Tierra Energy expects drilling to be completed in March, with testing and tie-in to existing facilities expected to follow in April.
