“Although a high level of production has been restored, MMS will continue to monitor the ever changing situation in the Gulf of Mexico,” said MMS Regional Director Chris Oynes.
MMS continues to monitor the progress made by the oil and gas industry in returning to pre-storm levels of operation in the gulf. As of January 31, 2005, approximately 135,756 barrels of oil per day (BOPD) and about 489 million cubic feet of gas per day (MMCFPD) remain shut-in.
MMS estimates that, of the approximately 4,000 structures and 33,000 miles of pipelines in the gulf, 150 platforms and 10,000 miles of pipeline were in the direct path of Hurricane Ivan. This path brought Hurricane Ivan across the shelf and through the waters of the Mississippi River delta, the area most susceptible to underwater mudslides in the gulf.
Hurricane Ivan destroyed seven platforms as indicated in Table 1 and caused significant damage to 24 other platforms, 16 of which remain off production. Of the 16 platforms that remain shut-in, 14 are shelf facilities as indicated in Table 2, and two are deepwater facilities as indicated in Table 3. Any additional damage will be detected with underwater surveys required by the MMS Notices to Lessees (NTL 2004-G18 and NTL 2004-G19). With industry still conducting underwater structural damage assessments, the number of platforms with significant damage could still increase. However, updated projections tentatively have all remaining deep water facilities being back online by April 2005. (See Table 3)
Numerous pipelines have been identified that were damaged because of Hurricane Ivan. Thirteen pipelines that were damaged because of mudslides remain shut-in (See Table 4), and there were an additional four pipelines with a diameter longer than 10 inches that were damaged by other forces, all of which remain off production. (See Table 5)
MMS is also going to conduct engineering studies to examine the precise structural forces that were experienced by the platforms during the hurricane. MMS received $500,000 from Congress to contract out technical studies of the impact of Hurricane Ivan. Competitive award proposals for these studies are being prepared.

Table 2 – Major OCS Shelf Platforms Remaining Shut-in with Significant Damage
* Indicates underwater structural damage on platform as a result of Hurricane Ivan.
A major platform is defined as a structure with either six or more completed wells or zero to five completed wells with more than one item of production process equipment regardless of the amount of production.
Significant damage is defined as damage that prohibits production or requires complete structural analysis of the platform before returning to production
Table 3 – Deepwater Facilities Remaining Shut-in with Significant Damage
Since the October 8 th MMS press release, three deep water facilities were removed from the significant damage list because they have been repaired and are currently online. The platforms were: Dominion’s MC 773, Murphy’s MC 582, and Shell's VK 956.
