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 reservoir and flow specialists in partnership with subsea hardware specialists, Trendsetter Engineering.

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.

Solving the diagnostic puzzle of blowouts

The importance of effectively and safely managing subsea operations is central to the foundations of Add Energy.

Formed in the wake of a blowout on the Norwegian continental shelf more than 30 years ago, Add Energy’s well control company was set up, originally as Well Flow Dynamics, by three of the key players involved in the incident, to design and develop unique solutions to mitigate the impact of future oil spills.

Australia’s leading Well Intervention workshop OWI AUS is going virtual this year to ensure the well intervention community remains up to date, engaged and connected, and will be hosted by the Offshore Network.

This year, Add Energy’s EVP of Drilling and Well Engineering, Eduardo Robaina has been selected to moderate a virtual workshop and webinar at the event on “Integrity Excellence”, with NOPSEMA’s Well Integrity Manager, Mark Bourne and Sarah Robertson, a Well Engineering Supervisor form ExxonMobil.

Behind the scenes with the Deepwater Horizon Investigation team

Behind the scenes with the Deepwater Horizon Investigation team

On the evening of April 20th, 2010, a well integrity failure allowed hydrocarbons to escape from the Macondo well into Transocean’s Deepwater Horizon rig, resulting in explosions and fire in which 11 people lost their lives and 17 were injured. This incident caused a spill of national significance as hydrocarbons continued to flow from the reservoir for 87 days, resulting in the most expensive oil spill in history.

Add Energy were called in to be part of the core investigation team, to independently investigate the events that led up to the incident. Our Head of Well Control, Morten H. Emilsen was brought into this tightknit team of experts to analyse and examine all possible causes and to provide expert recommendations to enable prevention of similar events in the future.


We interviewed Morten to understand the part that Add Energy played in this crucial investigation and what he learned from working on one of the biggest hydrocarbon disasters to date.

 

How did Add Energy come to be involved in the investigation?

Boosting production amid a cost-conscious environment

The impact of COVID-19 has resulted in many operators delaying investment into new projects and looking for opportunities to improve operating efficiencies and lowering costs for projects that are already in play.  

Production optimization is a key component to survival and assuring production remains economically viable and safe.
