Mesh 40, 50
CENOLITE
2621900090
Mesh 40 and 50 hollow fly ash cenospheres used as lightweight oil well cementing additives. This grade helps reduce slurry density and hydrostatic pressure in weak, depleted, or loss-prone formations.
▸ This product is selected for oilfield systems where lightweight density control and downhole stability are required.
▸ The hollow aluminosilicate structure helps reduce slurry or fluid density while maintaining inorganic chemical stability.
▸ Particle size, floatation, density, and strength should be confirmed by batch data and application testing.
▸ Density Control: Low true density helps reduce hydrostatic pressure in cementing or drilling systems.
▸ Good Floatation: High floatation supports stable suspension and reduces density segregation risk.
▸ Downhole Stability: Ceramic aluminosilicate chemistry resists common oilfield chemical environments.
▸ Mesh Selection: Controlled mesh size helps match slurry or fluid rheology requirements.
▸ Technical Traceability: COA and specification data can support oilfield project documentation.
▸ Low-density oil well cement slurries
▸ Lead slurry systems
▸ Weak and depleted formations
▸ Lost circulation prevention
▸ Deepwater and low-pressure cementing
