Number: RS22182 Title: Unocal Corporation's Oil and Gas Authors: Bernard A. Gelb, Resources, Science, and Industry Division Abstract: U.S.-based Unocal Corporation is primarily an oil and gas exploration and production company with operations in North America and overseas. China National Offshore Oil Corporation (Cnooc), which is largely owned by the government of China, has submitted a bid to acquire Unocal. Some Members of Congress and others are concerned that acquisition of Unocal by Cnooc poses a threat to the adequacy and dependability of U.S. energy supplies, and to national security as well. Data from the Unocal Corporation indicate that the bulk of Unocal's oil and gas production and reserves are located overseas. Pages: 4 Date: July 26, 2005
