PACIFIC RUBIALES ANNOUNCES PARTICIPATION IN OLEODUCTO BICENTENARIO DE
COLOMBIA

TORONTO, Nov. 15 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE; BVC: PREC) announced today that it has successfully obtained a 32.88% equity interest in Oleoducto Bicentenario de Colombia ("OBC"), the company that will build, own and operate a new oil pipeline in Colombia.

OBC is a special purpose vehicle promoted by Ecopetrol (BVC: ECOPETROL; NYSE: EC; BVL: EC; TSX: ECP), which has a 55.97% interest together with its affiliates, with the participation of other oil producers operating in Colombia, who will control the remaining 11.15% interest. OBC will be responsible for the financing, design, construction and eventual operation of Colombia's newest oil pipeline transportation system, which will run from Araguaney, in the Casanare Department of central Colombia, to the Coveñas Export Terminal in the Caribbean.

The new pipelines will add to the capacity of the existing pipeline systems connecting the Los Llanos Basin to the export markets, which are projected to reach full capacity as the increase in planned production from Colombian producers materializes in the mid-term.

The OBC project is planned to be executed in four phases:  

Phase 0:			Truck off-loading facility in Banadia with a capacity of 40,000 bbl/d - already under construction by Ecopetrol and expected to start operations in late November this year.
Phase 1:			Pipeline Araguaney - Banadia, 120,000 bbl/d
Phase 2-3:			Pipeline Banadia - Coveñas,  330,000 bbl/d

It is expected that the OBC pipeline project will be completed by the end of 2012 or the beginning of 2013. Completion dates are subject to engineering and financing milestones being met, and will be carefully reviewed once the final OBC project team is in place.

For the Company, the participation in this project is a perfect strategic fit, time and volume wise, as it moves towards reaching the goal of having a gross production of 500,000 bbl/d in the mid-term.

It is with this strategy in mind that the Company has committed to participate in Phases 0 and 1, acquiring the right to access approximately 40,000 bbl/day of transportation capacity by the end of 2011.

Under the terms of the participation agreement, the Company has the option to maintain its interest in OBC or have its interest diluted by the time the investment decision is made for Phases 2 and 3. The Company's decision to participate in Phases 2 and 3, which will give it access to an additional 110,000 bbl/d of transport capacity, will hinge on the coming on line of production from the STAR project in Rubiales and the development of the CPE-6 Block.

It is estimated that Phases 0 and 1 will require an aggregate investment of US$1.03 billion, excluding financing costs. The partners intend to finance the OBC pipeline project through project financing, with a debt/equity ratio of 70/30. This financing will be structured to maximize the use of export credit agencies and multilateral financing, as well as to access the Colombian capital markets.

The Company will have representation on the board of OBC and will play an active role in the financing and construction of the project. It is expected that equity contributions by the Company in the initial phases of the OBC will be funded through internally generated cash flow.

Ronald Pantin, Chief Executive Officer of the Company commented: "We are very happy to be able to participate in the OBC pipeline project and be the second largest shareholder. Our participation in OBC, in conjunction with our interest in the ODL pipeline and the transportation capacity secured in the OCENSA pipeline, will cover the transportation needs arising from our aggressive production expansion plan in the mid-term."
