During early 2012 Sudelac was approached by a Norwegian company, after seeing our float testing system, to design, develop and test a unique product to use as part of their novel well stimulation system. The product was to be run on the end of the liner, allow circulation, prevent back-flow, but also be triggered to be shut-off and hold 5,000psi of pressure prior to the well stimulation process. The project was completed on time and on budget and a commercial system supplied in a tested and ready to run state. It is expected that the Sudelac Two-Way Check Valve Shoe will be used when the well stimulation project starts well trials in 2013.
