Sufficient quantities of WAB’s were purchased to achieve multiple barriers per well during the drilling and completion of the 17 wells planned for development of the Moho Nord field. The wells will be completed in water depths of 450 to 1200 meters producing from the Albian reservoir via a tension leg platform.

“The Moho Nord project is the biggest oil project to date in the Republic of Congo. Total E & P Congo are determined to deliver this project efficiently while assuring integrity of the wells for their full life. Welltec has supported our operations in Congo for years with their technologies and methodologies for well interventions,” states Philippe Labrugère, the Project’s Drilling Manager.

“So when Welltec introduced the WAB® to us, we immediately identified the advantages it could offer to improve efficiency, assure integrity and successfully deliver such a complex project.”

The Welltec® Annular Barrier (WAB®) is an expandable, metal barrier which can we used for well integrity, zonal isolation or cement assurance applications. It won the OTC Spotlight on New Technology in 2015 as one of the latest, most advanced technologies that are leading the industry into the future.

Documented right down to the smallest detail

The new Transformation Center in Denmark, which manufactures the award-winning completion product, the Welltec® Annular Barrier, is now celebrating its one-year anniversary. Facility manager, Vagn Nielsen, takes stock and unveils a state-of-the-art quality system.

It has been 12 months since the new Transformation Center opened. How have the past months been?

Things have gone very well and the production is up and running. Currently we are working on orders for some major operators from the Western as well as Eastern hemispheres. And we have already delivered many products for the North Sea and the Middle East.  All deployments have been exclusively successful.

And the employees are fantastic. They will stand shoulder to shoulder with each other to continue making this a success. The atmosphere is good, and people are great at cooperating and helping each other.


Complete traceability

You mention state-of-the-art manufacturing quality, what has been implemented?

Yes, indeed. It has been an exciting and successful process, where we have established and configured procedures in a way that matches our needs.

For example, we have integrated complete traceability into the new facility giving us and our customers full control of all applied material. All the way down to the individual piece of raw material that is used to create the smallest parts, from cradle to grave. We can simply control and ensure the highest quality on every single piece that is a part of our delivered products.

You almost go to extremes with traceability. Why is that?

There are several aspects to it. But the main reason is that the Welltec® Annular Barriers (WAB®) are new technology; steel that gets expanded. And once a WAB® has been expanded and set, you can’t just replace it with a new one, it’s permanent. Therefore it’s paramount that the products perform as required, which is why we ensure that every single WAB® is of the highest quality. The tracking and monitoring is one of many aspects that help us guarantee reliability.


Full transparency

Looking back the past 12 months, what are you most proud of?

Our clients’ reception of what we have done, that is for sure one of the successes.

But also, the results from establishing good processes. For example, our welding procedures where we operate with a bar code system, everything has to be scanned in every step of the way and if something doesn’t match, the work can’t be done. This ensures that all bits, people and materials meet the criteria established for the highest quality product – criteria that we require to be met before we even begin welding.

In addition, the extra feature we’ve created, where clients can follow the entire process through a live video camera. In this way, they can get fully acquainted with the processes as it is carried out as well as seeing where the quality data comes from during the welding.

Clients can monitor visually the welding and by personal remote-inspection ascertain that we are adhering to the required limits.

Why is this relevant to the customers?

The fact that we work with full transparency around our production has been received very well. It gives clients confidence in our quality processes, evidence that we don’t at any level compromise the quality of their product.

Also, we often have clients who travel from the other side of the globe to inspect the manufacturing. Now this can be done without the physical presence which both saves time and flight tickets and creates a much leaner manufacturing process.


More like a laboratory

What other highlights has there been during the past 12 months?  

Our facility in general, the high degree of tidiness and orderliness, has been received with great respect. This should be common throughout the oil and gas industry, one could say, but from the feedback we’ve received I think we’ve raised the bar here as well.

From the very beginning, Welltec’s approach has been that you cannot create quality products in a mess. That goes for all our production facilities and production machinery: they all have to be entirely top notch. This is clearly reflected on our premises, which are bright, friendly and clean – you could say more like a laboratory than a manufacturing plant.

The new facility is called a “Transformation Center”. What is meant by that?

It’s a place where you contribute to not just changing things, but changing things radically and setting a new standard for our industry. We feel the products we make can do just that.

And products that make big changes like this can’t be left to uncertainty during manufacturing.  They are produced under optimal conditions for creating quality work that meets the high quality demands of the industry. At the end of the day, this is what makes the transformation possible and why we call it a Transformation Center.

“We pride ourselves on being a transformational company, one that develops technology with real, immediate impact” says CEO Jørgen Hallundbæk. “The WAB is another perfect example of our vision. Its universal application can significantly improve safety and efficiency in our industry, providing a reliable, effective annular barrier while eliminating the need and cost of cement.”

The Welltec Annular Barrier is a unique, metal expandable barrier with a large expansion ratio and high delta P capability. As a qualified, stand-alone barrier element, it precludes the need for cement in the construction phase for many applications. Its novel capabilities allow it to be expanded from surface, with no waiting times and conform to the surrounding open (or cased) hole environment.

Following on successful ISO V0 leak criteria qualifications in Denmark, the 9 5/8” V0 WAB was subsequently approved to meet a client’s Internal Barrier Policy based upon NORSOK D010 Rev 4, enabling them to apply this unique technology without the need for dispensation in the North Sea. The WAB was installed without cement to prevent surface annular pressure (SAP) buildup within the B annulus.

“Being recognized as an OTC Spotlight Technology Award winner is fantastic,” declares Paul Hazel, VP of Well Completions. “It’s the culmination of lots and lots of hard work by a great team at Welltec.”

Recently the capabilities of the WAB have accelerated rapidly, which is reflected in winning this award. The WAB now provides benefits for operators globally for safer wells with lower capex while providing higher productivity.

This is the fourth time we have won this prestigious award. Last time was in 2013 with the Well Cutter; in 2009 the Cleaner PST won whereas the Well Cleaner RCB was announced the winner in 2008. We will be awarded the trophy at a ceremony on May 4 during the Offshore Technology Conference (OTC) at 1530 to 1600 hours in Room 208 on level 2 in NRG Center.

Welltec® Annular Barrier (WAB®) Replaces Cement as a Primary Well Barrier

Welltec®, the world leader in cost effective well solutions, is pleased to announce that its Welltec® Annular Barrier has been successfully utilized to replace cement as a standalone, primary well barrier for the mitigation of surface annular pressure build-up.


Johnny Bårdsen
Sales Director, Well Completion, Scandinavia

Following on successful ISO 14310 V0 leak criteria qualifications in Denmark in November 2014, the 9 5/8” V0 WAB® was subsequently approved, deployed, successfully expanded and subsequently verified in a field which has historically been challenged by B surface annular pressure buildup.

Pressure build-up in the B annulus can potentially result in catastrophic well failures, lost production, high costs for remediation, extensive monitoring and control requirements.

“Approximately 40% of the global well stock suffers from failed barriers, cement contributing to a majority of these failures” states Paul Hazel, VP of Well Completions. “This product provides a new solution for operators to capitalize on.”

Prior to this operation, cement has been the main approved well barrier qualified to ISO/API and other industry standards for the use of mitigating annular pressure build-up.

The Welltec® Annular Barrier is a unique, metal expandable barrier with a large expansion ratio and high delta P capability. As a qualified, stand-alone barrier, it precludes the need for cement.
