The Relief Well Injection Spool (RWIS)

Blowout control hardware that allows well design to be optimized and assures single relief well contingency

Assure single relief well intervention, maximize production and cut CAPEX costs

The RWIS is patented specialist subsea hardware that enables well design to be optimized whilst allowing operators to stop a blowout from prolific reservoirs safely and efficiently via a single relief well, a solution that was co-developed by Add Energy’s well control and flow specialists in partnership with subsea hardware specialists, Trendsetter Engineering.

The RWIS is capable of pumping in excess of 200 barrels of kill mud into a blowing well per minute, increasing the pumping capacity by 300% by removing the bottleneck caused by restrictive choke and kill lines from the surface vessel to the seabed

Meet your production targets with less investment

Meet your production targets with less investment

Having access rights to the RWIS enables operators to increase the completion size of their well bore without compromising the ability to achieve single relief well contingency, enabling production targets to be met with fewer wells, resulting in reduced costs and risk

Secure approval for exploration and production projects with complex legislative requirements

Secure approval for exploration and production projects with complex legislative requirements

For particular companies and in regions where being able to demonstrate single relief well contingency is part of the fundamental requirements for project approval, having access rights to the RWIS provides this assurance measure to help get your project sanctioned

Minimize risk and unlock well kill efficiencies when the unthinkable happens

Minimize risk and unlock well kill efficiencies when the unthinkable happens

Reduce the support resources such as vessels, rigs, personnel and well control equipment to gain control of a hydrocarbon release in the most effective, safest and efficient way possible, using a single relief well to intersect the blowing well.

How it works

The RWIS is capable of pumping 200 barrels of kill mud per minute through a single relief well, which is quadruple the amount of kill fluid which is typically achieved.

This is made possible by removing the mechanical bottle neck caused by kill and choke lines of a conventional BoP riser system by hooking up flexibles below the BoP, to achieve much higher injection rates.

The NORSOK D-010 standard and why it is fundamental to well integrity management

Developed by Norway’s oil industry initiative, NORSOK, the well-respected D-010 standard for well integrity in drilling and well operations defines the minimal functional requirements for well design, planning and execution with the aim of maintaining well integrity throughout the life-cycle of the well. It includes a mixture of functional and prescriptive guidelines which are found very useful to operators, who use the standard as part of their management system and service contracts, and to regulators, who include references to D-010 as part of their guidelines.

Relief well planning and why you need it, with Add Energy’s Senior Vice President of Well Control and Blowout Support

Historically, relief well planning skills and knowledge were guarded in secrecy by a few industry specialists, however, it is a vital last line of defense in the case of a blowout. Add Energy’s course aims to provide a comprehensive introduction to relief well planning and what should be included in a plan so operators can drill more safely and react swiftly in the case of a blowout.

In this blog post, we speak to the creator of the course and Add Energy’s Senior Vice President of Well Control and Blowout Support, Ray Tommy Oskarsen. We ask him to share his valuable insights on what relief well planning is, what it requires, and why it is fundamental to any drilling and wells operation…
