• Nabors Industries Ltd., Houston, (NYSE: NBR) and Greenwich, Conn.-based private-equity firm First Reserve Corp. plan to form NFR Energy LLC to invest in oil and gas exploitation opportunities worldwide, with $1 billion in equity. NFR will pursue operated and nonoperated working interests, joint ventures, farm-outs and acquisitions with existing Nabors customers and other operators.

Calyon Securities (USA) Inc. analysts Mark S. Urness and John Marrin say, "...The creation of NFR is a relatively low-risk proposition that will leverage NBR's extensive drilling operations and new rig technology into interests in E&P properties. Nabors has made similar investments in the past that have done well, including the 20% interest that it took in a joint venture with Lehman Brothers and El Paso (NYSE: EP) back in October 2003."
