Finding 1 - The oil and gas industry has embarked on an important ‘next generation’ series of exploration and production operations in the ultra-deep waters of the northern Gulf of Mexico (Appendix D). (On the basis of the available evidence, the committee has identified the principal causes of the incident, as summarized above and described in the report in greater detail. Efforts to reduce the probability of future blowouts should be complemented by capabilities of mitigating the consequences of a loss of well control. Staging equipment at three Strike Teams and 19 sites near existing Coast Guard buoy tenders best used the available personnel and vessel resources adjacent to primary oil spill threat areas.

The approach chosen for well completion failed to provide adequate margins of safety and led to multiple potential failure mechanisms. Achetez neuf ou d'occasion … The first relief well was able to intersect the well and permanently seal the Macondo well.

Macondo Well-Deepwater Horizon Blowout examines the causes of the blowout and provides a series of recommendations, for both the oil and gas industry and government regulators, intended to reduce the likelihood and impact of any future losses of well control during offshore drilling. The flow of hydrocarbons that led to the blowout of the Macondo well began when drilling mud was displaced by seawater during the temporary abandonment process. 0000781566 00000 n A first article field and factory acceptance testing program ensured all equipment functioned as specified, eliminating costly errors. 0000008392 00000 n Industry, BSEE, and other regulators should improve corporate and industrywide systems for reporting safety-related incidents. 1399 0 obj <> endobj 0000008430 00000 n 0000075162 00000 n The report presents the consensus view of a committee of 15 experts convened by the National Academy of Engineering (NAE), operating through the National Research Council (NRC), in response to a request from the Secretary of the U.S. Department of the Interior (DOI).

Finding 1 - The oil and gas industry has embarked on an important ‘next generation’ series of exploration and production operations in the ultra-deep waters of the northern Gulf of Mexico (Appendix D). Furthermore, advances in BOP technology should be evaluated from the perspective of overall system safety. The well was originally planned for a total depth of 19,650 feet. 0000009390 00000 n Given the critical role that margins of safety play in maintaining well control, guidelines should be established to ensure that the design approach incorporates protection against the various credible risks associated with the drilling and completion processes. Sealing the well to ensure that no hydrocarbon flow occurs is critical to the temporary abandonment process. 0000011115 00000 n This was but one of a series of questionable decisions in the days preceding the blowout that had the effect of reducing the margins of safety and that evidenced a lack of safety-driven decision making. Industrial management involved with the Macondo well–During the course of its investigations, the committee made several observations with regard to the processes and procedures used by industry and government regulators.1. The blind shear ram failed to sever the drill pipe and seal the well properly, and the emergency disconnect system failed to separate the lower marine riser and the 5. xref (4. Operating companies should have ultimate responsibility and accountability for well integrity, because only they are in a position to have visibil-ity into all its aspects. contain a blowout at the Macondo well, mitigate the damage resulting from the millions of gallons of oil flowing from that well into the Gulf of Mexico, and compensate the hundreds of thousands of individuals and businesses harmed by the spill.

A decision was made in early April 2010 to halt drilling at a total depth of 18,360 feet and prepare the well for temporary abandonment in order to utilize the well later for oil and gas production. 0000004673 00000 n
The sequence in which they are presented is not intended toimply a sense of priority. There were also enormous consequences for the companies involved in the drilling operations, to the Gulf of Mexico environment, and to the economy of the region and beyond.
