The statement of commercial viability means that, after evaluating the results of the exploratory phase and testing stages, Ecopetrol confirms the potential of the field and decides to begin the commercial production stage.

The field has a commercial area of 305 hectares and is owned 100% by Ecopetrol. The original volume of hydrocarbons in situ is estimated to be 62 million barrels, of which unaudited proven oil reserves are calculated to be 5.4 million, with 9.9 million barrels of probable reserves.

The field's current output is 1,600 barrels of crude per day (bpd). The development plan calls for increasing such output to 5,500 bpd by 2012 with the application of secondary recovery technologies, especially water injection.

The field is operated through a services and technical collaboration contract for the area of Casabe between Schlumberger and Ecopetrol.  

The commercial viability of the Casabe Sur field contributes to Ecopetrol's strategy of incorporating reserves in areas surrounding production fields and helps reach the Company's production goal of one million barrels of oil equivalent (oil and gas) per day by 2015 and one million three hundred thousand barrels of oil equivalent per day by 2020.

Ecopetrol is Colombia's largest integrated oil & gas company, where it accounts for 60% of total production. It is one of the top 40 oil companies in the world and the fourth largest oil company in Latin America. The Company is also involved in exploration and production activities in Brazil, Peru and the United States Gulf Coast, and owns the main refineries in Colombia, most of the network of oil and multiple purpose pipelines in the country, petrochemical plants, and it is entering into the biofuels business.

This release contains forward-looking statements relating to the prospects of the business, estimates for operating and financial results, and those related to growth prospects of Ecopetrol. These are merely projections and, as such, are based exclusively on the expectations of management concerning the future of the business and its continued access to capital to fund the Company's business plan. Such forward-looking statements depend, substantially, on changes in market conditions, government regulations, competitive pressures, the performance of the Colombian economy and the industry, among other factors; therefore, they are subject to change without prior notice.
