Bidding alone and with partners, the company was successful on 20 total bids, representing an expenditure of $143 million net to Anadarko. The bids are subject to approval by the US Interior Department’s Minerals Management Service.

Anadarko said that its winning bids were primarily focused on high-impact, drillable targets in the Miocene play. The blocks, which cover 115,200 gross acres, range in water depths up to 10,085 feet. Anadarko will be the designated operator of all of these high bid leases with an average working interest of approximately 78%.

Anadarko noted that it is the largest independent leaseholder in the deepwater Gulf of Mexico (GoM). With the addition of these new blocks, Anadarko will have access to 633 blocks covering 3.5 million gross acres. During the remainder of 2008 and 2009, the company plans to drill 10 to 15 exploration or appraisal wells in the deepwater GoM.

Bob Daniels, Anadarko’s senior vice president for worldwide exploration, said: The deepwater Gulf of Mexico continues to be a key component of Anadarko’s growth strategy, and our lease-sale effort was focused on securing additional acreage around our existing leasehold, while adding a few new drill-ready opportunities aimed at continuing that growth.
