TORONTO, Sept. 14 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE) announced today the start of operations of the Oleoductos de Los Llanos pipeline. This pipeline was built and will be operated by ODL, a special purpose vehicle structured for the project, where Ecopetrol (US:EC-N) and Pacific Rubiales hold a 65% and 35% interest, respectively.

This pipeline connects the Rubiales heavy oil field, located in the Los Llanos Basin, to the Monterrey station in the Casanare department of Colombia, where it will connect with the OCENSA pipeline, allowing for the transport of the crude from the field to the Caribbean export terminal of Covenas.

With a length of 235 km and a diameter of 24 inches, the initial capacity of the pipeline is 60,000 barrels per day, which will then increase to 160,000 barrels per day by the first quarter of 2010. With further investment the pipeline may transport up to 260,000 barrels per day. The pipeline is totally buried and was designed and built to minimize its environmental footprint.

Total investment for the project was US$ 530 million, excluding financing costs. During the peak of activity, the project employed 4,685 workers, most of them from the areas neighbouring the path of the pipeline.

This project, the largest of its kind in Colombia in the last decades, stands not only as the cornerstone of the development of Rubiales, but also as a key component of the future development of the hydrocarbon potential of the entire Llanos Orientales basin.

Ronald Pantin, Chief Executive Officer, commented: "With the coming on line of the ODL pipeline and the associated infrastructure field, we enter into a new phase of the development of Rubiales, reducing significantly our transport costs and eliminating the road transport restrictions. This pipeline will also play a key strategic role in the development of this emerging oil basin".

Javier Gutiérrez, President of Ecopetrol, was also quoted as saying: "This is a key strategic project for the development of the Colombian heavy crudes and it is an integral part of Ecopetrol's stated strategic goals for 2015".

Pacific Rubiales, a Canadian-based company and producer of natural gas and heavy crude oil, owns 100 percent of Meta Petroleum Corp., a Colombian oil operator which operates the Quifa block in the Llanos Basin in association with Ecopetrol S.A., the Colombian national oil company. The company is focused on identifying opportunities primarily within the eastern Llanos Basin of Colombia as well as in other areas in Colombia and northern Peru. Pacific Rubiales has a current net production of approximately 36,000 barrels of oil equivalent per day, with working interests in 32 blocks in Colombia and Peru.

Boe may be misleading, particularly if used in isolation. A boe conversion ratio of 6 mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
