Welltec can look back at an impressive first half of 2013 with exhibitions in North America, Europe, Middle East, Asia, Africa, and South America, nine technical papers, 18 presentations, and two product awards, but we are by no means resting on laurels. During the fall season we will be exhibiting at SPE NAICE (Nigeria), Deepwater Intervention forum (USA), Offshore Europe (UK), ATCE (USA), KIOGE (Kazakhstan), IADC Middle East Drilling (UAE), Kiev O&G (Ukraine), APOGCE (Indonesia), OTC Brasil, Deepwater Angola, ADIPEC (UAE), and ICoTA Roundtable in Aberdeen (UK). We are currently preparing another five papers and have been invited to give a number of presentations on e.g. Subsea Interventions. We look forward to seeing you in the fall!
When the 19th Underwater Technology Conference (UTC) recently took place in Bergen, Welltec’s Ole Eddie Karlsen, VP Subsea Solutions, presented a case story on the world’s first hydrate removal on e-Line from an RLWI vessel. Subsea wells and consequent operations are trending and this year’s UTC had a record turnout. The primary focus of the conference was the road ahead for subsea technology; deeper, colder and longer. Innovative and unconventional are key change factors to the industry, and thus Welltec was a natural presenter.

When the logging company Anega won a tender to do a series of PLTs in horizontal, production wells in Kazakhstan, they selected Welltec’s e-line 218 Well Tractor conveyance solution to save time and minimize operation costs. The conventional CT solution required ~four days operating time, hence the savings potential was significant.
The toolstring was run in hole in logging while tractoring (lwt) mode to target depth, providing higher data accuracy and real-time feedback during the operation. The Well Tractor provided good depth control, constant speed for the downpass and saved valuable rig up / down time.
The operation was carefully executed at a slower-than-normal pace to allow continuous reassurance of logging capability, yet it only took 27 hours per well – a significant time saving compared to CT conveyed logging.

In June, Welltec’s Senior Vice President, MENA, Brian Schwanitz, was invited as part of the SPE Distinguished Lecturer program to give speech at the first formal meeting of the newly formed SPE Kirkuk section. This was the first time a Distinguished Lecturer has ever visited any of the three Iraqi sections and the presentation spurred a great interest. The topic was Intelligent Interventions and as Iraq does not have ready access to coiled tubing units, swift and nimble e-line solutions, like Welltec’s, are exactly what they are looking for.

The first run of Welltec’s groundbreaking, high temperature, DC electronics were among the cases discussed when Welltec recently presented four specific high temperature intervention cases at an SPE forum in Georgetown, Malaysia. Most of the international and national operators in the region were present and both AC and DC Well Tractor cases were well received.
Welltec also experienced a very strong pull from participating companies for our HT-WAB products that are part of the new Completion Solutions. These can remove a gap for many operators to continue with HPHT exploration.

When an operator in the North Sea experienced problems running a 2 1/2” inflatable plug through a Baker “F” nipple profile with an internal diameter (ID) of 2.562” in a producing well, offshore Norway, Welltec proposed a solution utilizing two custom milling bits.
System Integration Testing was conducted to establish operating procedure, determine the suitable bit design and optimum weight on bit (WOB) needed for this world’s first operation.
Two bits, consisting of a unique Metal Matrix Compound (MMC), were manufactured for this specific operation, 2.677” and 2.638” respectively, to grind through the nipple profile leaving the surface smooth to ease further interventions. They were designed so that if the first bit wore down before the nipple was milled through, the second bit could pass through the milled section and finish the job without getting stuck.
No restrictions were found in the well down to the nipple depth and a toolstring consisting of the Well Miller® NPR with the custom 2.677” milling bit was run in hole. After about two hours of effective milling time, the power consumption changed and the tool was returned to surface, where the milling bit did not show significant wear. The toolstring returned into the well with the same bottom hole assembly (BHA) configuration. On this run it passed through the nipple profile without problems. Several more passes were made to confirm depth and easy to pass through.
In a few short days, using only e-line equipment the operator was able to remove the restriction, set a straddle packer and restore the well to production; without the use of a workover rig or CT unit.

Since 2001, Danish founded Welltec has been established in Calgary, Alberta, and has had its own setup to serve the Canadian oil & gas industry with intervention solutions. Now, because of the success of the Canadian team in Welltec Canada, the Welltec Canada team is being honored by being awarded the Danish Export Associations Diploma and HRH Prince Henrik of Denmark’s Medal of Honor.
“I am tremendously proud to be part of a team, that has delivered the results that Welltec Canada has done”, says Scott Bittner, Area Vice President for Welltec Canada, “Even if I am new to the team, it is very clear to me that the team of Welltec Canada is not only focused on driving business locally here in Canada, but also has excellent collaboration with their colleagues in Denmark and elsewhere. I believe that one of the key levers that the team in Welltec Canada pulls to be successful is to bridge the needs for our Canadian clients with our capabilities in Canada and the rest of Welltec. In my view this is a very effective way of building a business”.
Welltec has been active in Canada since 1997, and in 2001 it was decided to establish a branch in Canada, with headquarters in Calgary, Alberta. Now, Welltec Canada has a wide-spread network of bases in Canada and has grown its business well above CAD 40 million a year.
“Welltec Canada is important both for Welltec in the Americas and in the Welltec Group itself. It is one of our largest country markets, and yet still one of the faster growing ones”, says Senior Vice President of Welltec Americas Carl Strubberg, and continues “as a team effort, Welltec Canada has developed from scratch to become a full, all-encompassing subsidiary of Welltec and one of the key ones in Welltec. Being based on sound principles, effective operations and a well-adapted business conduct, there is no doubt that the Welltec Canada has the potential to grow much further, and contribute much more to the export of Danish technology based services in the future.”
Great potential on the Canadian market
Canada has the second largest oil reserves in the world, and there is great demand for the products and solutions Welltec Canada Inc. provides. The market has also contributed to the development of new technologies that have helped Welltec’s presence globally.
Besides being an important export market for Welltec, the company is also convinced that the Canadian market has potential to grow even more. Since the team behind Welltec Canada Inc. has already mastered to bridge the cultural gap between the Danish company and the Canadian oil and gas industry, there are great opportunities for future growth.
Welltec Canada Inc. therefore contributes to the growing export of Danish technology for one of the world’s most important industries, on one of the largest markets, and has thus opened the door to future exports of other Danish products and solutions.
The Danish Ambassador Erik Vilstrup Lorenzen in Canada presented the award at a ceremony at Welltec Canada’s headquarters on June 7.
“I am honored to be presenting the Prince Henrik of Denmark’s Medal of Honor to Welltec Canada. Through innovation, excellent client service, and with hardworking and dedicated employees, Welltec continues to be very successful. I hope Welltec Canada will serve as an example for other companies to follow,” says Erik Vilstrup Lorenzen, Danish Ambassador to Canada.
Welltec participated in the Congreso Mexicano del Petroleo in Cancun this year. The stand featured our new Welltec Annular Barrier – or WAB™ – which is part of our new segment of Completion Solutions. The WAB™ received a lot of attention from the industry, which has a strong demand for flexible, reliable completions that can last the lifespan of the well.
The secret behind the WAB™ is that it offers an elastomer-free, expandable metal packer with great strength designed to deliver flawless zonal isolation or cement assurance in all environments. It even precludes the need for cementing thus enabling truly extended reach wells.

Welltec presented two out of the 11 presentations at the 8th ICoTA Stavanger meeting. Both presentations concerned RLWI operations performed from the Island Constructor in the North Sea, demonstrating our continued success in delivering ‘heavy’ interventions with e-line.
The first of the two presentations concerned a recent clean-out job in which we successfully removed hydrates from a water injection well. When pipe pulse pressure yielded no results, the operator chose Welltec to remediate the problem, as our Well Cleaner RCB was less likely to generate rapid gas release from the hydrate than alternative solutions. The hydrate was present below the subsea tree, but the length was unknown. In less than 20 hours of actual milling time, 173 ft (52 m) of hydrates were removed to a depth that allowed the operator to re-establish functionality to the downhole safety valve. You can read the full case story here.
The second presentation concerned milling through a deep set bridge plug bullnose in a highly deviated well in order to reestablish production from the lower reservoir formation. The plan was to pull the bridge plug to gain access to the screen sections; however due to a restricted ID in the liner, the plug could neither be released nor retrieved. Hence, milling was the only option. Welltec delivered a tailored solution designed to penetrate through the entire bridge plug, and proceeded to mill through the plug’s bullnose without complications.
