Add Energy and Trendsetter’s well optimisation hardware, the RWIS, receives US patent

Add Energy and Trendsetter Engineering Inc (TEI), the co-developers who created the Relief Well Injection Spool (RWIS), have announced that their well optimisation hardware has been granted a US patent.

About the RWIS

 The RWIS has been designed and built to enable operators to stop a blowout from prolific reservoirs safely and efficiently via a single relief well by increasing the pump rate of kill mud into the blowing well. The RWIS is capable of pumping more than 200 barrels of kill mud per minute through a single relief well, four times as much kill fluid as typically achievable. A significant advance for the industry which utilizes multiple vessels as opposed to the alternative method requiring multiple relief wells.


In addition to the RWIS assuring single relief well contingency, the RWIS also enables operators to optimize well economics and help unlock projects that wouldn’t normally be sanctioned. In purchasing access rights to the RWIS, operators are able to comply with legislation and reduce the number of wells required to meet production targets by increasing the completion size of the well bore, reducing CAPEX costs and maximizing production.

 

The Patent

The patent protects the commercial use of and manufacturing of the RWIS apparatus and method for killing a blowing well.


Brett Morry, Global Technical Director at TEI commented on this recent advance: “This is a water shed moment for both of our companies and further solidifies the RWIS’s unique capability to optimise well design while assuring single relief well contingency.


Morten Haug Emilsen, Senior Vice President at Add Energy commented: “The unique combination of competence and experience from both companies were essential to materialize an idea that has been in our minds since 1989. For Add Energy, the patent validates the belief in the collaboration between Add Energy and TEI and gives a clear message that this hardware presents a viable solution to an existing industry problem.


Over the last year, access rights to the RWIS have been contracted by several operators across multiple wells in various regions, and momentum around gaining access to the RWIS continues to grow with additional operators currently evaluating its use for upcoming wells.

How to increase your well kill injection rates by 260%

Following the Deepwater Horizon Oil Spill Disaster in 2010, regulators and operators increased their focus on blowout contingency planning with significant emphasis on well capping, relief well drilling and dynamic kill operations. In particular, Norwegian drilling and well regulations now states that a permit for drilling can only be granted if well control can be regained by intervention with just 1 relief well. 

This case study demonstrates how single relief well contingency can be achieved using a Relief Well Injection Spool (RWIS) - a piece of specialist subsea equipment that enables operators to stop a blowout from a prolific reservoir safely and efficiently, by increasing the pump rate of kill mud into the blowing well.

In being able to kill a blowing well with just 1 relief well as opposed to 4 intercepts, this operator experienced significant cost savings, a reduction in resources required and made zero modifications to the size of the completion bore as direct impacts of using the RWIS

How to Achieve Single Relief Well Contingency

Add Energy and Trendsetter Engineering’s article on Single Relief Well Contingency has been published in the SPE Norwegian Magazine, December 2017 edition.

The article discusses advice on how to manage and comply with the most recent changes to drilling and well regulations in Norway, where changes in relation to Section 86 were updated in 2015 and now states: "In the event of a well control incident, it shall be possible to regain well control by intervening directly in or on the well or by drilling one (1) relief well.”
