Stable, continuously mixed mud removal system
Reduce the risk of gas migration, zonal communication, and complete job failure due to fluid train intermixing.
CemPRIME engineered chemistry spacer is customized based on several factors and well conditions. Temperature, nonaqueous fluid (NAF) base oil, and salt concentration in the spacer are considered while designing and blending a custom chemistry package.
CemPRIME spacer is compatible with both cement slurries and NAFs and does not deteriorate cement slurry thickening time or compressive strength development upon contamination. The spacer surfactants and solvents act as effective cleaners and demulsifiers in a wide range of temperatures, base oils, and spacer salinity.
To further enhance mud removal performance, CemPRIME Scrub engineered scrubbing spacer contains fibers that improve mud removal in wells where conventional chemistry-based mud cleaning systems are inadequate. Fully compatible with spacer, cement slurry, and drilling muds, this spacer is compatible with conventional systems but significantly improves rotor cleaning.
Results are repeatable and robust due to the improved laboratory protocols and apparatus used to measure spacer performance. The HT cleaning apparatus has the ability to heat fluids up to 356 degF [180 degC]. The complex behavior of the spacer downhole can be simulated in the laboratory to observe the impact on cement, cleaning, spacer stability, and emulsion inversion.
Optimize drilling fluid removal through efficient cleaning and emulsion inversion.
The CemPRIME engineered chemistry spacer is customized based on specific wellbore conditions and other pertinent selection criteria to remove drilling fluids more effectively prior to cementing, and is particularly applicable to wells drilled with nonaqeuous fluids.
