CALGARY, ALBERTA--(Marketwired - Dec. 9, 2013) - Talisman Energy Inc. (Talisman) (TSX:TLM)(NYSE:TLM) and Ecopetrol (ECP) (NYSE:EC)(TSX:ECP)(BVC:ECOPETROL) today announced an important milestone towards developing the Akacías field in Block CPO-9 in Colombia in the Department of Meta.

The co-venturers are in the process of completing a successful nine-well appraisal program following the Akacías discovery in 2010, and are now ready to move forward with field development. A Declaration of Commerciality has been submitted to the regulator and a conceptual field development plan will be filed within the next 90 days.

In making the Declaration of Commerciality, the two companies announce the following:

  • Eight successful appraisal wells have been drilled in 2013 in the Akacías field, with one additional well currently drilling.
  • Current production of 7-9 API oil from three wells on long-term test is 5,300 bopd, which will ramp up as the remaining wells are put on long-term test.
  • To date, 1.5 million barrels of oil have been produced from the Akacías-1 discovery well, which commenced long-term test in May 2011 with average production in excess of 2,000 bopd.
  • Transportation of the oil to market is occurring via the capacity the two companies have in the San Fernando and Ocensa pipeline systems.
  • The original oil in place mapped with the currently producing wells is 1.3 billion barrels. Assuming a 10% recovery factor, a 2C contingent resource of 130 million barrels of oil is indicated.
  • Structurally deeper wells drilled but yet to be placed on long-term test indicate greater oil in place; recoverability is yet to be determined.

Upon receipt of the required environmental licence, additional appraisal and development drilling will commence to determine the full extent of the Akacías field. All activity in Akacías and Block CPO-9 will continue to be conducted in a safe, environmentally and socially acceptable manner.

"We are pleased to be working with Ecopetrol as our partner and operator of Block CPO-9 on the important Akacías oil discovery, and are encouraged by the results to date," said Hal Kvisle, President and CEO of Talisman. "We will now move forward to agree on a development plan and obtain the necessary environmental permits. This milestone reflects a material step towards realizing the potential of our Colombian business and will bring significant benefits to Colombia."

"Akacías constitutes one of the major exploration achievements in recent years in Colombia, and clearly shows the heavy crude potential in the Llanos area, the target of Ecopetrol's exploration campaign to reach its goals of producing one million barrels of clean oil equivalent in 2015 and 1.3 million barrels of oil equivalent in 2020. We will continue working together with our partner, Talisman Colombia, in the assessment and development not only of Akacías, but also of the potential existing across all the licensed area," said Ecopetrol's CEO, Javier Gutiérrez Pemberthy.

Ecopetrol is the operator of Block CPO-9 and has a 55% interest in the license. Talisman has a 45% interest in the license. The Akacías area borders the Cubarral Block, where the Castilla and Chichimene oil fields are located.

Resources In this news release, Talisman discloses best estimate contingent resources (2C) as at December 5, 2013. Contingent resources are defined as those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. The key contingencies that prevent the subject resources from being classified as reserves are: facility engineering design; development plan approval; and environmental license approval. There is no certainty that it will be commercially viable to produce any portion of the resources. In addition to these contingencies and uncertainties, the development of commerciality of resources is also subject to a number of risk factors, as discussed more fully above. Any resources data contained in this news release reflects Talisman's estimates of its resources. While Talisman annually obtains an independent audit of a portion of its proved and probable reserves, no independent qualified reserves evaluator or auditor was involved in the preparation of the resources data disclosed in this news release. In this news release, estimates of resources for individual properties may not reflect the same confidence level as estimates of resources for all properties, due to the effects of aggregation.
