Field-proven cement kits specially designed for use in bailer applications

Applications

  • Zone isolation
  • Water shutoff
  • Well abandonment

Features and Benefits

  • Good particle suspension in the slurry reduces the risk of settling in the bailer, which results in time saved by avoiding additional remedial runs.
  • Minimal water loss reduces the risk of premature setting in the bailer, which minimizes the number of runs and equipment damage.
  • Delayed development of static-gel strength prolongs thickening time (low rheology), enabling easy flow out of the bailer and saving time and money by eliminating the need for additional runs.
  • HIP Mix kits resist gas migration to obtain a sound isolation barrier, saving time and money in additional remedial runs.
  • Multiple slurry densities are available to fit the well conditions.
  • The kits are formulated for a short initial set time (less than 12 hours) after the slurry has been dumped, which results in reduced downtime.
  • The kits are also formulated to achieve high-compression strength development (less than 24 hours).
  • Post-set expansion results in high bonded shear strength to casing, which saves time and money by reducing the number of runs needed.
