Welltec® Annular Barrier (WAB®) Installed as a Primary Well Barrier

16 January, 2015

We have achieved a breakthrough in the industry with our Welltec® Annular Barrier (WAB®). For the first time in the world it has been run as a standalone, primary well barrier element. This is a truly exceptional accomplishment as the WAB® hereby has delivered a solution to a challenge that affects an estimated 40% of global wells: mitigation of pressure within the B annulus.


Johnny Bårdsen
Sales Director, Well Completion, Scandinavia

When pressure migrates within the B annulus the effects can be catastrophic, costing lives and causing wells to be shut in. The WAB® solves these issues by providing a tight seal, thus preventing pressure build-up in wells. Further advantages include avoiding remedial work to establish cement barriers when the primary cement operation has failed and offering daily monitoring of the B annulus within wells to maintain production.

This world’s first achievement took place in the North Sea for Statoil where the 9 5/8” ISO14310 V0 WAB® was deployed; successfully expanded and subsequently verified on a well in a field which has historically been challenged by B surface annulus pressure buildup.

“It’s a milestone for the industry that this technology has become available,” states Øystein Eikeskog, Principal Engineer of Well Technology, Statoil. “Not only will this save us significant time during well construction, it provides significant mitigation of future B annulus pressure issues where other methods have failed.”

Following on successful ISO V0 leak criteria qualifications in Denmark in November 2014, the 9 5/8” ISO14310 V0 WAB® was subsequently approved to meet Statoil’s Internal Barrier Policy based upon NORSOK D010 Rev 4, enabling Statoil to apply this unique technology without the need for dispensation for this particular well.

“This is truly an outstanding achievement and demonstrates our continued efforts to provide disruptive innovation in the marketplace,” states Paul Hazel, VP of Well Completions for Welltec®. “The natural progression of this product continues at a steady pace, enabling a new perspective for well integrity considerations.”

The Welltec® Annular Barrier is a unique, expandable metal 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.

The novel, expandable metal well annular barrier’s capabilities have been accelerating over the past four years and now provide an alternative to cement as a primary well barrier element.

1,500 lbs of Sand Removed on E-line

We have set another record with our powerful clean-out solution. During an operation in the North Sea the Well Cleaner PST retrieved a total of 1,500 lbs of sand with up to >300 lbs in two of the runs. The operation actually started as a drift run but owing to the remarkable efforts by the Well Cleaner the job went from drift to world record performance.


Terje Skeie
Senior Vice President Scandinavia

The well had a history of sand production, but at the time of the operation the operator was not certain of the hold-up depth (HUD). As they now wanted to inspect the integrity and add more perforations it became important to establish the exact HUD. First they wanted to run the Well Cleaner RCB as a drift run for debris removal and determination of the HUD. However, this plan changed quickly as our clean-out solutions demonstrated just how effective they are.

A broad range of e-line clean-out technologies executed nine successful runs. On two of these runs we sat a record by removing >300 lbs of sand – in each run.

In total over 1,552 lbs of sand was successfully collected over a distance of ~ 1,735 ft. This enabled the operator to perform the logging run and make an informed decision on the perforations.

Our outstanding execution demonstrated how light, e-line clean-out solutions can deliver many of the objectives that the operator has for other wells without a workover rig or coiled tubing unit.

Well Cutter® Provides 75% Cost Reduction

“A cut worthy of a king!”

Those were the words by the company representative after the Well Cutter® had cut through hard scale and tubing – in the same run.

This accomplishment took place offshore Norway where a large build-up of BaSO4 had restricted the ID of the 7” tubing to just 5.45”. The overall objective was to cut the casing, but in order to reach it the Well Cutter® would have to cut through the hard scale first.


VP Marketing
Brian Sidle

At 6,717 ft depth the Well Cutter® successfully broke through the scale and cut the tubing, all in the same trip downhole. This took only three hours in total.

It was the first time we used the Well Cutter® to both cut through scale and tubing, but the operation clearly demonstrates the value of the tool. Significant rig time was saved and costs reduced considerably as a consequence. In total, the operator saved approximately 75% of the costs by performing the entire operation on e-line compared to a rig-based operation.

41 Perforation Runs Increases Efficiency, Oman

Our ability to conduct operations safer and more sustainably were made evident when we enabled an operator in Oman to optimize the intervention strategy. And not only did our e-line solution ensure safer interventions, it also generated valuable time savings on these horizontal perforations.


VP Marketing
Brian Sidle

Previously, the operator had been conducting perforations using coiled tubing conveyance. Although successful this method was also time-consuming as the rig-up procedure was lengthy and the operating times extended. Therefore the operator decided to apply Welltec’s e-line Well Tractor® as the preferred conveyance solution.

In total, a 1,916 ft long total interval was successfully perforated using the 2 1/8” Well Tractor. This was accomplished over four phases in order to test the flow between the different perforation stages.

Being able to conduct all the perforations on e-line secured a much more efficient operation both in terms of time and costs compared to the alternatives. Noticeably fewer people were required on location which, combined with the lightweight nature of our e-line technology, reduced risks and also eliminated heavy lifts.

Extended Unconventionals? Extended Efficiency!

Clean-outs can be performed in extended, deviated wells with great efficiency. We know because we just did it and we have a long track record of efficient e-line clean-outs.


VP Marketing
Brian Sidle

This operator in Eagle Ford, Texas, had been attempting to convey a production logging string on coiled tubing (CT) in their extended horizontals. After numerous unsuccessful efforts they approached us to provide an alternative on e-line. There were a few operational challenges: a 4,681 ft long horizontal section plus a well deviation of 89°, which made the Well Tractor the perfect conveyance solution.

In addition, it was believed that a specific type of debris from a previous frac plug milling operation had not been picked up on the CT clean-out run. This was causing CT to reach early lock-up. To remove the debris the Well Cleaner Power Suction Tool High Flow (PST HF) was requested due to previous achievements for the same operator.

After two runs the Well Cleaner PST HF conveyed by the Well Tractor had retrieved all the mixed materi­al composite buttons from the frac plugs. This cleared the way for the Well Tractor to convey the PLT to total depth as planned. The successful operation demonstrated how efficient the Well Tractor is for performing logging runs in extended unconventionals.

By retrieving the debris to surface instead of dispersing it downhole, our clean-out solution allowed the operator to analyze the recovered material. This will provide valuable information when planning future interventions in the well.

The e-line intervention improved logistics and avoided the need to mobilize tanks of fluids as the Well Cleaner PST drags the debris into built-in bailer sections rather than injecting fluids into well. A further benefit of the Well Cleaner PST is the ability to operate in producing wells, which increases efficiency and allows for continued production.

The Welltec® Annular Barrier is a unique, all metal expandable barrier with a large expansion ratio and high delta P capability. It can be used to prevent flow between casings or between casing and open hole to provide cement assurance, to prevent build-up of surface annular pressure or to create compartmentalization within the reservoir or isolation between reservoirs.

For the test, a 9 5/8” version of the WAB® was expanded into a 13 3/8” casing within a test cell. There it was exposed to pressured nitrogen while undergoing axial loads and temperature cycles without experiencing any leaks. Witnessed by a number of representatives from global operators as well as Welltec staff and management, the test was successfully completed in accordance with ISO/API standards.

“This qualification is the next significant step in a series of successes for the WAB®,” says Paul Hazel, VP of Well Completions. “These have included being incorporated as part of the primary well barrier and being installed for zonal isolation in wells capitalizing on cementless completions.”

Ricardo Reves Vasques, VP Engineering, states “Of course the testing wasn’t easy. It has taken almost three years of research, but we’ve always believed that this technology could achieve this high standard and we wouldn’t give up until we had accomplished it.”

A brief description of the levels of ISO/API standards for packers can be found at Petrowiki®.

Welltec® is the largest provider of tractor technology for conveyance solutions as well as the foremost supplier of milling, clean-out and mechanical solutions for e-line interventions. Our novel, expandable metal annular barrier’s (WAB’s) capabilities have been accelerating for the past four years and comprise the foundation of the Flex-Well® completion concept.
