SPC
Spacer & Preflush Additives
Surfactant and suspension packages used in spacer and preflush fluids to improve mud removal and cement bonding ahead of primary cementing.
Application
Primary cementing where engineered spacer or preflush is required between mud and cement. Formulation depends on mud type, temperature and contact time.
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.
Cement class compatibility
API Class A–H (per additive type)
API 10A / ISO 10426-1
Spacer rheology / contact time
Engineered per well conditions
API RP 10B-2 / field design
Compatibility with mud / cement
Lab-tested for planned sequence
API RP 10B-2
Reference profile for orientation. For each supply we confirm grade, origin and certificate data against your specification, well conditions and delivery requirements.
