The Lago Agrio oil field is an oil-rich area near the city of Nueva Loja in the province of Sucumbíos, Ecuador. It is located in the Western Oriente Basin. Hydrocarbon-bearing formations are the Cretaceous Napo and Hollin formations.〔 〕〔 〕 Oil was discovered in the area in 1960s. The Lago Agrio field is known internationally for the serious ecological problems that oil development has created there, including water pollution, soil contamination, deforestation and cultural upheaval. Since 1993, lawyers representing local residents have sought to force former well operator Texaco and its now parent company Chevron Corporation to clean up the area and to provide for the care of those allegedly affected. In February 2011, an Ecuadorian court ordered Chevron to pay $8 billion in compensation, a ruling the company called "illegitimate" and vowed to appeal.〔 In March 2014, a United States court found that the 2011 Ecuadorian verdict was obtained by the plaintiffs against Chevron through "coercion, bribery, money laundering and other misconduct." ==Development and ownership== In 1964, Texaco Petroleum Company (TexPet) began exploring for oil in northeast Ecuador, in an area which was inhabited by indigenous people. The following year it started operating a consortium owned equally by itself and Gulf Oil, to develop a tract in the area. Nueva Loja was originally founded as a base camp of Texaco. The consortium struck oil in 1967 and began full-scale production in 1972. The Ecuadorian government, through its national oil company CEPE, now Petroecuador, obtained a 25% interest in the consortium in 1974. Gulf subsequently sold its interest to CEPE. By 1976, the consortium was majority-owned by the Ecuadorian government.〔(【引用サイトリンク】title=Judge, In Deposition Order, Lambasts Lawyer Suing Chevron )〕 TexPet transferred management of the consortium to Petroecuador in 1990. TexPet's concession expired in 1993, leaving Petroecuador as the sole owner. Petroecudaor continues drilling in the area.〔 Over a period of 20 years, the Lago Agrio field produced of oil with a profit of $25 billion. According to Chevron, 95% of the profit from the consortium went to the government. Chinese consortia Andes Petroleum and PetroOriental operate the Tarapoa Block in Sucumbios and blocks 14 and 17 in Orellana. Produced oil is transported by the ''Sistema de Oleoducto Transecuatoriano'' (SOTE) and ''Oleoducto de Crudos Pesados'' (OCP) pipelines to the marine terminal at Balao.〔〔 〕 Lago Agrio is also connected by the San Miguel–Lago Agrio pipeline. The multiproduct Poliducto pipeline runs from Lago Agrio to Quito.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lago Agrio oil field」の詳細全文を読む スポンサード リンク
