Welltec

Danish oilfield services provider Welltec has bagged the seventh position in our rankings. Among the many notable products and technologies that form its upstream portfolio, the Welltec Annular Barriers (WABs) have proved to be quite successful for the company’s Middle East business. A number of WABs have been in operation in regional oilfields posing complex production issues. In these cases, no cementing technique could resolve the problem, so a WAB was deployed in the open hole in conjunction with cement, with the WABs preventing crossflow between two zones that previously led to cement channelling and failure. Deployment of WABs in operations has been deemed as an economical solution by Welltec’s customers.
