McMoRan Exploration Logs Pay at Two Wells

McMoRan Exploration updated its exploration and development activities including positive drilling results at Laphroaig and Hurricane Deep.

The Laphroaig exploratory well commenced drilling on April 8, 2006 and was sidetracked to a true vertical depth of 18,412 feet (19,515 feet measured depth). Following an unsuccessful production test in February 2007, McMoRan and Energy XXI (Bermuda) Limited (AIM: EGY) have deepened the well to a true vertical depth of 19,060 feet (20,250 feet measured depth) to test additional targets. Wireline logs have indicated that the well encountered a potential 56 net feet of hydrocarbon bearing sands over a 75 foot gross interval. McMoRan has rights to approximately 2,200 gross acres in this area and has a 50.0 percent working interest and a 38.5 percent net revenue interest. Energy XXI has a 31.5 percent working interest and an approximate 24.4 percent net revenue interest in the well. A private partner has the remaining interest. The well, located onshore in St. Mary Parish, LA, can be brought into production promptly utilizing existing infrastructure in the area.

The Hurricane Deep well at South Marsh Island Block 217 commenced drilling on October 26, 2006 and is currently drilling below a true vertical depth of 20,600 feet. Log-while-drilling tools have indicated that an exceptionally thick upper Gyro sand was encountered totaling 900 gross feet. The top of this Gyro sand is credited with a potential of 50 feet of net hydrocarbons in a 53 feet gross interval. These exceptional sand thicknesses suggest that prospects in the Mound Point/JB Mountain/Hurricane/Blueberry Hill area may have thick sands as potential Gyro reservoirs.

Additionally, previous wireline logs in the Hurricane Deep well have indicated 27 net of feet of hydrocarbon bearing sands over a 200 foot gross interval in a laminated Rob-L section and a potential 20 net feet of hydrocarbon bearing sands over a 70 foot gross interval in the Operc section. McMoRan plans to continue drilling to a planned true vertical depth of 21,500 feet. If successful, the well could be brought on line quickly using existing facilities in the area. The Hurricane Deep prospect is located in twelve feet of water on OCS 310, one mile northeast of the Hurricane discovery well which is currently producing. McMoRan controls 7,700 gross acres in this area. McMoRan has a 25.0 percent working interest and a 17.7 percent net revenue interest. This well would be McMoRan's seventh successful well in the OCS 310/State Lease 340 area.

The Cas exploratory well at South Timbalier Block 70 commenced drilling on January 30, 2007. The well is in progress and has a planned true vertical depth of 25,000 feet. The Cas prospect is located in approximately 65 feet of water. McMoRan controls 5,000 gross acres in this area. McMoRan has a 15.0 percent working interest and a 12.4 percent net revenue interest.

A rig is on location at the Cottonwood Point exploratory prospect at Vermilion Block 31 and drilling is expected to commence within the week. McMoRan has a 15 percent working interest and an 11.3 percent net revenue interest in the Cottonwood Point well.

As previously reported, the Blueberry Hill well at Louisiana State Lease 340 encountered four potentially productive hydrocarbon bearing sands below 22,200 feet. Testing of this well commenced in the fourth quarter of 2006 following the receipt of special tubulars and casing for the high pressure well. The well has been perforated but production has not been established because of blockage above the perforated intervals. Additional operations to clear the blockage and complete testing of the well are expected in the coming weeks. Information obtained from the testing of the Blueberry Hill well and the results of the Hurricane Deep well currently drilling will be incorporated in future plans for the JB Mountain Deep well, as all three areas demonstrate similar geologic settings and are targeting deep Miocene sands equivalent in age. McMoRan has a 35.3 percent working interest and a 24.2 percent net revenue interest in Blueberry Hill and a 35.0 percent working interest and a 24.8 percent net revenue interest in JB Mountain Deep.

Since 2004, McMoRan has participated in 15 discoveries on 29 prospects that have been drilled and evaluated. Five additional prospects are either in progress or not fully evaluated. McMoRan currently has rights to approximately 370,000 gross acres and plans to participate in drilling a total of 8-10 exploratory wells in 2007.
