Mariner Energy Reports No Sustained Material Damage from Hurricane

Mariner Energy, Inc. has provided a preliminary update on the impact of Hurricane Gustav on the Company's Gulf of Mexico production and assets. The Company has completed initial assessments of virtually all Mariner-operated offshore structures and received reports from most operators at its third-party operated assets.

Based upon these assessments and reports, it does not appear that any of the structures sustained any material damage. As of Thursday, September 4, approximately 220 million cubic feet of natural gas equivalent per day (MMcfe/d) of offshore production was online. Pre-hurricane production from Mariner's Gulf of Mexico properties was approximately 360 MMcfe/d.

  • Of Mariner's two largest producing assets, Northwest Nansen (East Breaks Blocks 602 and 558) resumed production on Tuesday, September 2, and start-up activities are underway at Bass Lite (Atwater Valley Block 426) with production expected to resume in the next few days.
  • Production operations have resumed at most shelf fields.
  • Full production from deepwater and shelf fields is expected when third- party pipelines and processing plants resume operations, which is expected to occur over the next several days as power is restored.
  • Development activities at the Mariner-operated Geauxpher field (Garden Banks Block 462) and exploration drilling at the Mariner-operated Surge prospect (Garden Banks Block 334) have resumed.
