KickStart Rupture Disc Valve

Overview Library

Streamlined fracturing operations

The KickStart rupture disc valve eliminates the need for coiled tubing– or tubing-conveyed perforating in the first stage of multistage stimulation operations. It thus offers a faster and more cost-effective method of starting the fracturing process, especially in horizontal and highly deviated wells.

The valve is run to the toe of the well as part of the casing string. After the casing has been cemented and tested, pressure is increased to burst the rupture disc, shifting a sliding sleeve and opening the valve, thereby exposing the formation to the fracturing fluid so that stimulation operations can begin. The valve’s helical exit ports have been specifically designed to reduce fracture initiation pressure and to provide 360° coverage so that fractures are initiated in the preferred plane. Two rupture discs provide redundancy.

Enhanced safety through dissolvable technology

Introduction of ELEMENTAL degradable technology has enabled the valve opening pressure to be set below the maximum casing test pressure, an especially desirable feature when the test pressure is close to the casing burst pressure. After the valve opens, a ball is dropped from the surface to land on a seat above the valve, sealing off the valve so that the casing above can be tested to the required pressure. The ball soon dissolves completely, enabling the fracturing operation to resume.
