Macondo: the disaster that changed the rules
On 20 April 2010, while completing work on an exploratory well in the Macondo Prospect, approximately
50 miles off the coast of Louisiana, the semi-submersible oil rig Deepwater Horizon experienced a
catastrophic blowout, leading to several crippling explosions and an uncontainable fire that resulted
in the deaths of 11 rig workers. Two days later, the rig sank in approximately 5,000 feet of water.
The accident severed the rig's connection to the seafloor, while the blowout preventer experienced
a complete failure, allowing oil from the reservoir to plume into the Gulf of Mexico. The federal
government estimates that the Deepwater Horizon incident released 4.9 million barrels of crude oil
into the Gulf of Mexico before the damaged well was stabilized on 15 July, making it the single worst
offshore incident in US history.
In the three years following the oil spill, the government and the oil and gas industry (the Industry) have
worked hard to create and implement new rules governing offshore drilling.
The Deepwater Horizon accident has led to a re-evaluation of deepwater drilling procedures. New
regulations have been implemented with a view to preventing future oil spill incidents and improving
the health and safety of both the environment and offshore workers.
This seems particularly relevant in a technological environment where an increasing number of oil and
gas projects involving ultra-deep drilling are being presented by various players.
Most people in the oil production business believe that the era of easy oil discovery is over, and many
of today’s oil and gas reservoirs are indeed to be found in increasingly difficult locations with complex
geologies. These locations include large, ultra-deep oil and gas reservoirs.
The (re)insurance sector still views these projects as extremely risky. SCOR’s objective is to incorporate
these new prospects into our existing portfolios as carefully as possible.
SCOR Global P&C’s Business Solutions division currently deals with a large number of ultra-deep drilling
projects. It is important for the underwriters, lawyers, regulators, financiers and engineers involved to
understand the risk exposure linked to these projects and to verify that the insureds are closely following
the new post-Macondo regulations.
