Three jack-up drilling rigs are missing, feared lost and at least one deep-water production system sustained damage to its drilling package after battering winds and waves from large Hurricane Ike ripped through the US Gulf oil patch last weekend.
Damage reports have been trickling in as contractors and operators attempt to restore production volumes to the region.
Driller Pride International said Tuesday its 250-foot mat slot jack-up Pride Wyoming was missing. The unit had been working in Ship Shoal block 283. Pride said it expects the rig will be a total loss.
Rowan Companies also has lost a jack-up. Its LeTourneau 52-class slot unit Rowan-Anchorage was not found after a fly-over inspection of its pre-storm location in Vermilion block 201.
Rowan added that its newbuild jack-up Rowan-Mississippi, which was undergoing outfitting near Sabine Pass, Texas, apparently was struck by another vessel during the storm.
Preliminary inspection revealed only minimal damage to the newbuild.
The other unit missing was reported earlier. Jack-up Ensco 74, a LeTourneau Super 116-C, had been working in South Marsh Island block 149.
Supermajor BP said inspection of its deep-water assets found that the Mad Dog spar in Green Canyon block 823 lost its derrick.
The rig aboard the spar is owned by Blake International. According to BP, the rig’s derrick toppled and is on the sea bed.
Several shallow water platforms are understood to have been destroyed by Ike.
Supermajor Chevron said it had lost some shallow water assets, but did not get specific.
Minerals Management Service reports that 28 of the 3800 offshore oil and gas production platforms in the Gulf of Mexico have been destroyed by Hurricane Ike.
Several other platforms have been reported as significantly damaged; information on those facilities is being compiled and will be released in the near term, said the MMS.
Initial estimates are that the destroyed production platforms produced a total of 11,000 barrels of oil per day and 82 million cubic feet of gas per day.
The damage has been reported through over flights by MMS, the oil and gas industry and the US Coast Guard.
