Rosetta Resources LLC

Rosetta Resources LLC has retained Tudor, Pickering, Holt & Co. to sell certain interests in Texas and Louisiana state waters and the Gulf of Mexico shelf. The assets in state waters include a 50% interest in 6,643 gross acres (3,321 net) in nine prospect areas of the Sabine Lake region and an average working interest of 46% in 4,260 gross acres (1,949 net) in four Galveston Bay fields. The Gulf of Mexico shelf assets include an average 60% working interest in East Cameron, High Island, Main Pass, Grand Isle, South Timbalier and South Pelto. Current net production is 18 million cubic feet equivalent per day. The rate prior to Hurricane Ike was 31 million per day (80% gas, 74% operated). Pre-storm level production is expected to resume in first-quarter 2009. Annualized cash flow from January through October 2008 is $90 million. Total proved reserves are 30 billion cubic feet equivalent net as of year-end 2007. The assets involve 26 recently producing wells, a portfolio of growth projects and infrastructure with some third party throughput. Significant upside exists in identified intervals behind sliding sleeve and behind pipe, as well as incremental value from artificial lift and compression projects. Additional drilling opportunities exist. The bid due date is Feb. 13. The effective date is Jan. 1. The closing date is March 27. Contact Danny Rathan, 713-333-7184.
