|Caño Limón oilfield|
|Partners||Ecopetrol, Occidental Petroleum|
|Start of production||1986|
|Current production of oil||73,000 barrels per day (~3.6×106 t/a)|
The Llanos basin is located east of the Eastern Cordillera (Andes) in Colombia. The bulk of the oil is found in deltaic sands of Eocene Mirador and the Upper Cretaceous formation. The average API gravity of oil is 29.5°.
The National Institute of Renewable Natural Resources and Environment repeatedly criticized the operation. In 1988, it found that the operators had taken inadequate steps to prevent environmental damage. Later in 1992, it conducted water sampling studies that found high concentrations of heavy metals and polycyclic aromatic hydrocarbons. It found that "because of the polluting effluents from Caño Limón, the receiving rivers and lakes are no longer fit for human consumption."
