Occidental has been an active investor in Colombia for more than four decades. Currently, Occidental has operations in the Llanos Norte Basin of the Arauca province near the northeastern border, and in the Middle-Magdalena Basin in the Santander Department.
In Arauca, Occidental operates the giant Caño Limón Field, an Occidental discovery that enabled Colombia to become an oil exporter after many years as a net importer. More than 1.2 billion barrels of oil have been produced at Caño Limón since Occidental discovered the field in 1983.
In the Middle-Magdalena Basin, Occidental has a working interest in the La Cira-Infantas (LCI) Field, which it operates in partnership with Ecopetrol. LCI is an improved oil recovery (IOR) project with large remaining reserves.
