Both Newfield Exploration and Stone Energy lost three structures to the winds and waves generated by last month's Category 5 storm.
Newfield said net production of 5.6 million cubic feet per day was wiped out due to the loss of its South Marsh Island 49 B, East Cameron 151 C and East Cameron 286 B structures.
Of its 115 operated platforms in the US Gulf, junior Stone Energy lost three South Marsh Island 108 D and Vermilion Block 255 A and B platforms.
