Occidental has been an active investor in Colombia for more than four decades. Currently, Occidental has operations in the Llanos Norte Basin in the Department of Arauca and in the Middle Magdalena Basin in the Department Santander.
In the Llanos Norte Basin, 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 1.4 billion barrels of oil have been produced at Llanos Norte since Occidental discovered the Caño Limón field in 1983.
In the Middle Magdalena Basin, Occidental has a working interest in the La Cira-Infantas (LCI) area, where it has coordinated an enhanced oil recovery (EOR) project in collaboration with Ecopetrol, Colombia's state-owned oil company, increasing LCI's production and reserves, and a working interest in the Teca area. In 2016, Occidental launched a thermal recovery pilot in the Teca-Cocorná Field to more easily extract heavy crude. The pilot is a collaborative effort with Ecopetrol, and is producing with better-than-anticipated results.
Occidental's Chipirón Field, also in the Llanos Norte Basin, has been recognized by Asociación Colombiana de Ingenieros de Petróleos (Acipet) for innovative efforts to safely produce oil and gas in a remote area of Colombia while preserving the environment.
