ACC
Cement Accelerators
Additives that shorten thickening and setting time of oil-well cement slurries in cold or time-critical cementing jobs.
Application
Surface and shallow strings, remedial cementing, and slurries where waiting-on-cement must be reduced. Type depends on BHCT and cement class.
Technical characteristics (quality certificate)
Typical values as stated on a mill quality certificate (passport) for a standard commercial grade. Actual lot values are confirmed in the COA / TDS for the selected manufacturer.
