    Interior Department releases well control regulations

    News // April 18, 2016

    US Secretary of the Interior Sally Jewell and Director of the Bureau of Safety and Environmental Enforcement Brian Salerno have announced final well control regulations to reduce the risk of an offshore oil or gas blowout that could result in the loss of life, serious injuries or substantial harm to the environment.

    The regulations represent one of the most significant safety and environmental protection reforms the Interior Department has undertaken since Deepwater Horizon, and builds upon a number of reforms instituted over the last six years to strengthen and modernize offshore energy standards and oversight.

    “The well control rule is a vital part of our extensive reform agenda to strengthen, update and modernize our offshore energy program using lessons learned from Deepwater Horizon,” said Secretary Jewell. “I applaud BSEE for their work to develop a rule that takes into consideration an intensive analysis of the causes of the tragedy, advances in industry standards, best practices, as well as an unprecedented level of stakeholder outreach.”

    The regulations build upon findings and recommendations from several investigations and reports concerning the root causes of Deepwater Horizon and extensive consultation with industry groups, equipment manufacturers, federal agencies, academia and environmental organizations.

    The final rule is a comprehensive regulation addressing all dimensions of well control, including more stringent design requirements and operational procedures for critical well control equipment used in oil and gas operations on the Outer Continental Shelf.

    Specifically, the final rule addresses the full range of systems and equipment related to well control operations, with a focus on blowout preventer requirements, well design, well control casing, cementing, real-time monitoring and subsea containment. The measures are designed to improve equipment reliability, especially for blowout preventers and blowout prevention technologies. The rule requires operability of equipment through rigorous testing and provides for the continuous oversight of operations, all with the goal of improving the reliability of equipment and systems to protect workers’ lives and the environment from the potentially devastating effects of blowouts and offshore oil spills.

    The regulations combine prescriptive and performance-based measures to ensure that oil and gas companies and offshore rig operators are cultivating a greater culture of safety that minimizes risk. Key features of the rule include requirements for blowout preventer systems, double shear rams, third party reviews of equipment, realtime monitoring data, safe drilling margins, centralizers, inspection intervals, and other reforms related to well design and control, casing, cementing and subsea containment.

    Based on robust, technical comments received during the rulemaking process, several adjustments were made to provisions of the proposed rule that are reflected in the final version. These changes preserve stringent requirements regarding the safety drilling margin, interval testing and major inspections for blowout preventers, and also incorporate criteria for alternative practices that are subject to review, justification and approval. This rule provides flexibility so that regulatory oversight keeps pace with technological changes, provided future innovations can meet the rule’s standards for safety performance.

    The proposed rule was based upon significant input received from various investigations and reports of the Deepwater Horizon tragedy, in which a cascade of multiple failures resulted in the loss of well control, an explosion and fire which claimed the lives of 11 individuals, and subsequent months-long spill.
