The Relief Well Injection Spool (RWIS)
Blowout control hardware that allows well design to be optimized and assures single relief well contingency
Learn moreAssure 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.

Secure access rights to the RWIS to

Stop a blowout via a single relief well
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
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
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
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.
