Oil and natural gas firm Stone Energy has entered into a definitive agreement to purchase Anadarko’s 25% working interest in the deep-water Pompano field, located in the US Gulf of Mexico, for $67m.

The deal also includes a 22% working interest in Mississippi Canyon (MC) Block 29, plus a ten percent working interest in portions of MC 72.

Net production from the Pompano field is about 1,000 barrels of oil a day and three million cubic feet of natural gas each day.

Stone said its estimate of proved reserves attributable to the acquisition is about 5.9 million barrels of oil equivalent, based on Netherland, Sewell & Associates year-end reserve estimate for Stone’s portion of the Pompano field.

The company said the estimate has been proportionately reduced for the different working interest.

The acquisition is subject to preferential rights (MC 29 and MC 72 only) and other closing conditions, and it is expected to close in the second quarter of 2012.
