Occidental Petroleum Corporation



Occidental Petroleum is a fossil fuel company headquartered in Houston, Texas, although it was based in Los Angeles for most of its history. It incorporates the assets of Andarko Petroleum from Texas and Kerr-McGee from Oklahoma, both of which were major fossil companies in their time. In Colombia, the U’wa Indigenous peoples successfully campaigned to force Occidental from drilling on their lands and to sell its concession to Ecopetrol. Occidental continues to operate the 780 kilometer long Caño Limón pipeline in Colombia to the port of Coveñas which has contaminated the Arauca, Capanaparo and Cinaruco rivers. It has been sued for providing military equipment to Colombian army used to massacre union members along the pipeline route. In Peru, Occidental has agreed to a confidential settlement in 2013 with the Achuar Indigenous community for 30 years of contaminating the Corrientes River basin.
