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.”
