VERTECHS PIRANHA Dissolvable Cement Retainer utilizes a sliding-valve assembly for remedial cementing operations or zone abandonment. It combines dissolvable metal, dissolvable rubber and fast-drillable mandrel, meaning after drill-out, the remainder and majority of the cuttings will dissolve downhole. The sliding sleeve is operated by a stinger assembly from surface and controls pressure from both directions. PIRANHA could be deployed with CHAMELEON fully dissolvable bridge plug for selective, temporary water shut-off operations.
