Total has signed agreements for a 20-year extension of its 15% participation in Abu Dhabi Gas Industries Limited Company ("Gasco"), alongside the Abu Dhabi National Oil Company (“Adnoc”, 68%), Shell (15%) and Partex (2%). Gasco was created in 1978 to process the associated gas from the Bab, Bu Hasa and Asab oil fields, extract the natural gas liquids (C3+) for the Joint Venture shareholders, and deliver the ethane and residue lean gas (essentially methane) to Adnoc. On behalf of Adnoc, Gasco also operates the processing and liquids extraction facilities of other associated and non-associated onshore gas, as well as fractionation, transportation, storage and export facilities related to the above operations. In Abu Dhabi, Total holds interests in the Abu Al Bu Khoosh field (75%, operator), in the Abu Dhabi Company for Onshore Oil Operations (ADCO, 9.5%), which operates the five principal onshore fields in Abu Dhabi, and in Abu Dhabi Marine (ADMA, 13.3%), which operates two offshore fields. Total also has interests in Abu Dhabi Gas Liquefaction Company (ADGAS, 5%), which produces LNG, LPG and condensates.
