Oilfield chemistry
INTRON spacerClean
Spacer-fluid surfactants
Surfactant selection for spacer fluids used ahead of cementing.
How it is used
Spacer surfactants help displace oil-based or synthetic-based mud and remove residues before cement placement. Formulation must account for the drilling fluid, spacer density, brine and cement system.
Application areas
- Spacer-fluid formulation
- Mud displacement before cementing
- Surface cleaning and wettability preparation
Formulation considerations
Non-ionic and anionic surfactant blends can be assessed for spacer-fluid formulations.
What we need to select a grade
- Mud type and base-fluid composition
- Spacer formulation, brine and required density
- Temperature, cement system and compatibility-test plan
Product data and handling
Request the current technical data sheet and safety data sheet for the proposed grade. Confirm dosage, compatibility, handling and supply requirements before use.
