VytalFAST possesses high shear strength. It can remain its shape and achieve effective layer isolation during high-pressure operations. It also can degrade at a controllable degradation rate.It is suitable for oil and gas production,for example multi-layer and multi-stage fracturing,pressure testing of tubing and casing,construction setting of completion tools,fracturing sliding sleeve pitching isolation,etc.
