The ODL Pipeline

The most important facility for the transport of crude oil constructed in Colombia during the last decade, the Llanos Orientales Pipeline ("ODL"), was inaugurated and commenced operations on September 14, 2009 in the Rubiales Field.

This pipeline transports the crude oil produced in the Rubiales Field and other fields in the region to the Monterey Station, where it connects with the national petroleum infrastructure that transports the crude oil to the exportation ports of the Caribbean. Currently, the pipeline transports 240,000 barrels per day, with a projected figure for the year 2011 of 340,000 barrels per day.

ODL in figures:

• Investment: $560 million dollars
• Length: 235 kilometers
• Diameter : 24 inches
• Capacity: 240,000 bbl/d
• Partners : Ecopetrol 65% - Pacific Rubiales 35%

Pursuant to the social responsibility policies of the partner companies - Ecopetrol and Pacific Rubiales - COP$3.496 million have been invested in social investment projects in the 22 townships and four municipalities of the area of direct influence. The projects were defined in conjunction with the communities, and involve the areas of basic sanitation, education, housing, institutional strengthening and recreation.

This important and bold infrastructure project was inaugurated by President Alvaro Uribe Velez (2002 - 2010) and the minister of mines and energy, at the time, Hernan Martinez Torres, the civil authorities of the departments of Meta and Casanare and the President of Ecopetrol, Javier Gutiérrez Pemberthy and the Chief Executive Officer of Pacific Rubiales, Ronald Pantin.
