BEIJING - China National Offshore Oil Company Limited (CNOOC) said Sunday Bridas Corporation, a joint-venture equally-owned by CNOOC International Limited and Argentina-based Bridas Energy Holdings (BEH), will acquire a 60 percent equity interest in Pan American Energy (PAE) from BP for approximately $7.06 billion.

The acquisition excludes PAE's assets in Bolivia, according to a statement on the website of CNOOC, China's largest offshore oil and gas producer.

CNOOC International, a wholly owned subsidiary of the company, and BEH have agreed to contribute about $4.94 billion to Bridas to finance 70 percent of the proposed acquisition.

The remaining 30 percent, or approximately $2.12 billion, will be satisfied by third party loans to be arranged by Bridas and additional contributions from CNOOC International and BEH.

Completion of the acquisition is conditional on, among others factors, all necessary government and regulatory approvals, and is expected to take place in the first half of 2011.

In the first half of 2010, CNOOC International and BEH completed the formation of a half-half joint venture in Bridas.
