PL-HST
Hydraulic stage cementing tool
Hydraulic stage cementing tool designed for running the casing in one section, with subsequent cementing in two stages. PL-HST sleeves are used when cementing casing of considerable weight and length, as well as in non-isolated intake zones in order to reduce repression on productive formations, as well as for collar cementing.
