Add Energy's Well Control Specialists present at the 2016 SPE ATCE in Dubai

The Society of Petroleum Engineers (SPE) Committee selected Add Energy to present on How to Develop a Well Specific Blowout Contingency Plan that Covers Engineering Analysis of the Deployment, Installation, and Soft Shut-In of a Subsea Capping Operation at their 2016 Annual Technical Conference and Exhibition (ATCE) in Dubai, UAE.

The paper describes a step-by-step planning process for developing a subsea capping plan. For many deepwater operators a subsea capping plan is an internal requirement, and in some regions it is also part of regulatory requirements. Since Macondo, many industry publications have discussed the equipment, connections, and interfaces needed for capping and containing a blowing subsea well, but they give little insight into developing a well-specific subsea-capping contingency plan. The planning process described in the presentation, which has been used successfully on multiple projects and source-control drills, involves assessing the feasibility of deploying a capping stack from a floating vessel, the weight and stability of the capping stack to overcome the force of the blowout jet, and dynamic flow simulations of closing the capping stack outlets without loss of well integrity. This process not only assesses the feasibility, complexity, and risk exposure of the capping operation, but may also justify further planning, studies, or expenditure.

The paper is authored by Ray T. Oskarsen, Morten H. Emilsen and Amir S. Paknejad of Add Energy, Mike Cargol of Trensetter Engineering, and Kwee Choong See of Shell International Exploration and Production.
