Removing lock mandrel to return well to production

An operator, offshore India’s East Coast, needed to remove a thru tubing sand screen (TTSS) in a well that was being converted to injector. The TTSS was placed thru a 3.5″ QX Lock Mandrel which was set on a 3.5″ SSD nipple.

A slickline operation had been unable to remove the TTSS even after more than 300 attempts of jarring. After thorough risk assessment and testing at the Welltec® yard, Welltec® mobilized to the well site. This was a platform, which in addition to crane and space limitations, had daylight only restrictions. It was Welltecs first operation of releasing a Lock Mandrel in the Asia Pacific region. The first run revealed debris on top of the sand screen and a clean-out run was performed with a Well Cleaner® PST High Volume. The subsequent run with the Well Stroker® successfully retrieved the TTSS and the operation was completed in a single day.

Downtime was reduced to just five days and the operator avoided having to mobilize heavy equipment with a much larger footprint. During subsequent well testing, well injection of 22,000 bwpd was achieved compared to 0 with TTSS in the well. The well is now ready for the operator to convert to an injector which will facilitate an increase in production from the depleting field.

The Flex-Well™ takes a big step forward

The industry received Welltec’s new technology for cementless completions and zonal isolation with much excitement and positive feedback at the SPE/IADC Conference and Exhibition in Amsterdam, March 5-7th.

“With the introduction of the Welltec Annular Barrier, the Flex-Well vision becomes a reality. We have been looking forward to this launch for years,” says Paul Hazel, VP Well Completion Solutions at Welltec, and explains: “The Flex-Well™ concept significantly reduces total well construction, risk, time and costs, maximizes early production and increases ultimate recoverables without compromising the long-term well integrity. It delivers inherently safer wells.”

The WAB™ is the first of its kind in the market; a new generation, all metal, expandable barrier, designed for life-of-well, that enables cementless completion and zonal isolation under a wide range of operating environments. The WAB™ for zonal isolation has been tested to withstand conditions up to 10K Delta P and 300°C, and can set in minutes. Many of the shortcomings of current open hole or cased hole packers are eliminated with the introduction of the WAB™. It is nimble and rugged to install and provides a much higher reliability and success ratio both in the short-term as well as the long-term.

“We had a very successful launch of The WAB™ – it was well received. We experienced great interest due to its unique capabilities and the prospect of the whole Flex-Well™ solution. It clearly fulfills a need among the operators and we are proud to once again push the boundaries beyond what was thought to be possible only a few years back!” says Paul Hazel and concludes: “We could not have done this without our excellent and dedicated employees, and the cooperation of the various operators who have been involved.”

The HSE award will be presented to the team in Angola who participated in the successful installation of 160 meters of straddle packer assembly for gas shut-off on the HUN-105. This was a complicated, multi-run, rigless operation requiring seamless interface.
The entire job, consisting of one drift run and sixteen isolation assembly runs, was accomplished without any HSE incidents over a period of fifteen days. Welltec worked in alignment with the e-line and slickline companies in an effective team setting to deliver this incident free operation. A major part of the success is attributed to the high level of planning and discipline while executing the operation program as per Welltec Quality Plan, HSE, and QMS guidelines.


Welltec Wins OTC 2013 Spotlight on New Technology

COPENHAGEN, Denmark – Welltec’s latest e-line innovation, The Well Cutter™, has won the OTC Spotlight on New Technology award as one of the latest, most advanced technologies that are leading the industry into the future.

“We’re very proud to win this prestigious award with our Well Cutter™ and even more proud of the way it’s been received by our clients. On its first job, a 4 ½” 12.6 #/ft tubing in a well offshore Russia, the operator was so satisfied that he claimed the Well Cutter™ provided the ‘perfect cut’,” says Lars Mangal, Chief Commercial Officer, Welltec

The ‘perfect cut’ is enabled through robotic, e-line technology providing accurate depth control. The tool uses a self-centralizing rotating head to remove pipe incrementally, preventing the creation of shavings. The tool can cut pipe in a physical state of tension or compression.

“The resulting cut is a smooth, polished surface, which may preclude the need for a polishing trip,” explains Niels Falkenberg, Chief Technology Officer, Welltec.

“The Well Cutter™ delivers efficient drill pipe and casing recovery without explosives, leading to important HSE and operational improvements. Explosives can pose an operational risk, especially when simultaneous operations are being conducted. And the transfer of explosives can create additional logistical challenges, which may lead to operational delays.” he adds.

Considering the cost of rigs, complex logistics and exposure to personnel, the Well Cutter™ offers a safer, faster, reliable and more cost-effective approach to cutting drill pipe and casing.

Each year OTC recognizes innovative technologies with the Spotlight on New Technology Awards. To win, the technology must be less than two years old, innovative, original and proven either through full-scale application or successful prototype testing. It should have a broad interest to the industry and provide significant benefits beyond existing technologies. The environmental impact is also an important judging criterion.

The Well Cutter™ will be on display at the Welltec booth #1453 at OTC 2013 in Houston, May 6-9.
