A Dual Technology Solution for Downhole Safety Valve Scale Treatment

Treating and removing scale build-up within a tubing retrievable subsurface safety valve (TRSSSV) can be problematic, costly, and timely. For scale dissolvers to work effectively, they require extended soak periods to penetrate the scale. What if there was a solution that combined traditional soaking methods with a ‘jetting’ action, targeting scale dissolvers directly at critical components of the downhole safety valve, agitating the scale as well as soaking it? Introducing the NEW Oilenco Bullheading Jetting Sleeve. Combining two tried and tested technologies in one tool, the Bullheading Jetting Sleeve delivers optimum scale treatment results by using a repeated method of scale soak and targeted jetting. Requiring minimal well intervention, this innovative product is designed to precisely target critical areas within the TRSSSV using a ‘jetting’ action to optimise distribution and efficacy of scale treatment. Designed with a minimum of two jet subs, the system is preconfigured to target key mechanical components within the TRSSSV before being deployed into the well on slickline. Unique to the Bullheading Jetting Sleeve is the multi-jet sub system. Each jet sub consists of an array of micro nozzles that create a 360⁰ jetting pattern. By positioning two or more jet subs at key locations within the safety valve (i.e. flow tube, exercise profile, flapper, etc.) scale dissolver can be precisely targeted at these critical areas.
