Drilling permit is first for well with MWCC capping stack

Written by  

mwccstackmicroBOEMRE yesterday approved a fourth deepwater drilling permit that complies with the onerous new safety standards implemented in the wake of the Deepwater Horizon explosion and resulting oil spill. These standards include satisfying a requirement to demonstrate the capacity to contain a subsea blowout.

The approved permit is a revised permit to drill a new well for Exxon Mobil Corporation’s Well #3 in Keathley Canyon Block 919 in 6,941 ft water depth, approximately 240 miles off the Louisiana coastline, south of Lafayette, La.

“Today’s permit approval is the fourth to be approved in the month since the industry confirmed its capability to contain a deepwater loss of well control and blowout. We will continue to review and approve applications that demonstrate the ability to operate safely in deep water,” said BOEMRE Director Michael R. Bromwich. “As we have seen, the rate of deepwater permit applications is increasing, which reflects growing confidence in the industry that it understands and can comply with the applicable requirements, including the containment requirement. We expect additional permit approvals in the near future.”

ExxonMobil’s Well #3 is a new well. The operator had a rig on-location and an approved Permit to Drill a New Well when activities were suspended due to the temporary drilling suspensions imposed following the Deepwater Horizon oil spill.

ExxonMobil has contracted with the MWCC to use its capping stack to stop the flow of oil should a well control event occur. As part of its approval process, the bureau reviewed ExxonMobil’s containment capability available for the specific well proposed in the permit application and confirmed that the capabilities of the capping stack met the requirements specific to the proposed well’s characteristics.
