CemPRIME Scrub
Engineered scrubbing spacer
Enhances cement bonds with better hole cleaning, augmented by scrubbing fibers.
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 has minimal effect on 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.
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.
For wells with extreme cleanup challenges, CemPRIME Scrub engineered scrubbing spacer enhances spacer design with fibers.
