Add Energy continues to assist LNG Operator to Optimize Production from their Mature Wells

Add Energy has been collaborating with Australia's most experienced LNG operator for over 10 years, delivering solutions that will enable them to optimize production from their mature wells.


For more than a decade, Add Energy has assisted our client with production critical maintenance by troubleshooting and testing wellheads, as well as lower and upper completion components. This can only be achieved by coordinating site integration testing, equipment readiness and logistics activities in preparation for operations.

To help with production critical maintenance, an Intervention team model was created by Add Energy in 2008 with the objective of:

  • Planning and executing rig-less activities

  • Providing wellhead maintenance

  • Troubleshooting and replacing safety valves

  • Performing water shut-offs

  • Temporarily suspending wells

  • Carry on lubricating and bleeding operations

  • Increasing productivity through re-perforation activities

  • Executing production and corrosion logging operations

One of Add Energy’s responsabilities was to ensure that the assurance process was being adhered to and being constantly reviewed and updated. The purpose of this was to assure that work scopes were being delivered ahead of time and budget, with no uncontrolled hydrocarbon releases to the environment and no Health and Safety events.

Fundamental priorities that highlight Add Energy’s commitment to ensure safe offshore operations in accordance with the client’s  health, safety and enviromental culture.

Add Energy’s safety and delivery performance has been proven and demonstrated through:

  • More than 100 wells successfully intervened

  • Over 300 weeks of offshore activity

  • More than 30 quaterly reviews

  • Zero recordable LTI (Loss Time Incidents)

  • Zero discharge to the environment

  • History data base from over a decade

  • Strong process safety record

  • Great personnel safety performance > 98% HSE participation

  • Successful delivery of front end planning

  • Successful implementation of back to back travel / logistic plan

Add Energy continues implementing the design and execution processes that have enabled the Intervention Team to be successful.

Add Energy understands the responsibility of live well interventions, on a manned platform, and has demostrated to have the systems, people, and processes to deliver a high quality end product over the last decade.

Add Energy’s Well Control Experts Contribute to High Profile Subsea Intervention Events

In the aftermath of Deepwater Horizon, offshore energy companies joined together to form the company HWCG. With the mission of developing a comprehensive and rapid deep-water containment response system for the Gulf of Mexico, each company committed to a mutual aid agreement, sharing assets and resources in the event of an incident. Add Energy sent a team of well control experts to participate in HWCG's annual spill drill.


This two-day annual training exercise event, observed by the Bureau of Safety and Environmental Enforcement (the Gulf of Mexico regulatory agency), was hosted by W&T Offshore with 232 participants from multiple operators. The event was aimed at bringing a hypothetical deep-water blowout under control. All participants engaged and aided W&T Offshore to evaluate and plan how this particular loss of well control event can be brought back under control, ending the mock blowout scenario. Add Energy’s Well Control and Blowout Support Engineer’s played a crucial role in providing the simulations that helped the decision makers determine how to best plan how to successfully kill the blowout successfully ending the event.  The Add Energy team also provided expert advice on discharge modelling, flow assurance, subsea capping operations and relief well planning while participating in this exercise. A more detailed breakdown of what the two days would have consisted of can be found here.

During the same week, Add Energy also participated in the  2018 SPE Subsea Intervention Conference, in Galveston on August 8th, to present in the regulatory session.

The presentation, titled “Well Optimization and Best-Practice Compliance with the Relief Well Injection Spool” was delivered by Add Energy’s Well Control Expert, Ray Tommy Oskarsen, in collaboration with Trendsetter Engineering and was extremely well received. The presentation offered advice to operators on how to demonstrate the capacity to achieve single relief well contingency in order for permission to be granted to drill a well in the North Sea and Barents Sea.

Ray Tommy Oskarsen commented: “The RWIS played a pivotal role in the presentation due to recent changes in legislation which mandates that operators must demonstrate that they can achieve single relief well contingency in the event on an incident.

This shift in legislation was a key driver for Add Energy and Trendsetter’s creation of the RWIS, a patented subsea hardware that enables operators to stop a blowout from prolific reservoirs safely and efficiently via a single relief well. We believe that the RWIS is fundamental in unlocking projects that wouldn’t normally be sanctioned in regions where legislation mandates single relief well contingency.”

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 well is your well? Four things to consider to get the most from your asset and prevent failure in the future

It’s impossible to over emphasize just how important an effective well integrity program is to the safety and optimal performance of your well.


Imagine your completion was your car. If it was burning too much gas, leaking oil, smoking, or the tires were wearing thin, you would want to address those issues before embarking on a long car journey.

Well integrity is very similar to a car servicing plan where an effective well integrity plan can make sure your well is ready for the long journey of production. 

Developing a quality well integrity process and having robust plans in place is therefore critical to achieving production excellence and safety integrity. However, despite the criticality that surrounds the topic of well integrity, many companies do not have the fundamentals in place and continue to expose themselves and the environment to significant risk.

But to be effective, well integrity has to start in the concept design stage, making sure you’re going to get the most from your well even before a drop of oil has been delivered. 

So, if you are about to embark on this journey, or are already well into your journey of production and are looking for help in how to optimize what you have – you’re in luck.  Here are four key considerations companies should think about as they review and refine their design, construction, handover and production programs.

During Well Design

Far too often we see a lack of a long-term well lifetime view during this initial, critical stage. Investing in the well integrity process in the formative stages of well design could likely head off a number of issues we see during production. A few problems in design we see are:

  • Specification of equipment that will not last over a well’s long lifetime
  • Poor cement isolation design for aquifer zones above the casing shoe
  • A focus on initial well cost and disregard for future repair work

To address this gap, the best option is to involve the well integrity team at the early design stage and get their input on the design and long-term well utility. 

During Well Construction

One of the biggest issues in well construction is a lack of minimum acceptance criteria for the installation of critical barrier elements.  Equipment or cement has to be verified when it’s installed and before the well is handed over to production. When the focus is on costs or schedule, the verification steps are often reduced to the critical steps required to drill ahead or complete the well. 

To address this gap, the verification steps required for long-term well integrity should be built into the schedule and the cost estimate. This ensures the well can be produced with confidence and that the right barriers are in place.   

Well Handover (from Drilling and Completion to Production)


Communication of the ‘as built’ well details should be one of the simplest processes because all of the well design and construction information has already been collected. But too often we see a breakdown in communication of the details required to understand the operating limits and constraints once the well is completed.

The handover information should include the general specifications associated with “that type of a well” and also all of the unique features and history of the individual well. 

During Production

There are a number of items that can compromise well integrity during production. Some problems include a lack of well specific, well operating procedures (initial clean up, bean up, bean downs, shut-ins, maintenance, interventions, etc.) or changes in the well conditions. A well is not static but needs to be monitored and maintained to preserve the production capability. Many operators do not monitor their wells and are surprised when well problems develop, even when the signs have been present for years.

Well integrity requires monitoring your well integrity conditions over time. This can be a simple system or complex software with automatic data collection. But monitoring allows for problems to be identified and dealt with before they become too big and harder to control.  

All of this provides a system for wells that is the same as maintaining your car. It is much easier, and safer, to change your tires when they wear out than to change one on the side of the road after it fails. 

Well integrity systems provide confidence that your well won’t have a problem when you least expect it.

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
