Note 9 — Subsequent Event
     On October 28, 2011 we entered into a definitive agreement to sell our interest in one of our offshore Gulf of Mexico fields to an unrelated third party for approximately $80 million. The sale will be accounted for as an adjustment to our net full cost pool with no gain or loss recognized since the adjustment is not expected to significantly alter the relationship between capitalized costs and proved reserves.
