OILFIELD CHEMICALS
LWS-042
JUMP TO
GENERAL DESCRIPTION
LWS-042 hollow glass spheres are engineered for oilfield cementing formulations. With a specific gravity of only 0.42, LWS-042 offers a lower loading level than Q-Cel ONG 52/52B, providing formulators a more efficient path to density reduction. The result is reduced slurry densities with maintained workability and superior compressive strength — making LWS-042 the ideal choice where weight reduction and mechanical integrity are both critical.
Other Names & Identifiers
- Hollow Glass Spheres
- Lighteweight Cementing Additive

Common Challenges
- Weight On Cement
- Low Top of Cement
- Poor Strength Development
- Lightweight (Water Extended)
APPLICATIONS & BENEFITS
APPLICATIONS
APPLICATIONS & BENEFITSLWS-042 is recommended for use in:
- Lightweight primary cementing operations.
- Cementing across weak, depleted, or low-fracture-gradient formations.
- Lost circulation mitigation cement systems.
- Deepwater and extended-reach well applications.
- Remedial cementing operations requiring reduced slurry density.
- Any cement design where both weight reduction and compressive strength are critical performance requirements.
FEATURES & ADVANTAGES
APPLICATIONS & BENEFITS- Requires lower loading levels compared to Q-Cel ONG 52/52B.
- Enables the formulation of ultra-lightweight cement slurries.
- Maintains slurry workability and pumpability.
- Supports superior compressive strength development compared to traditional lightweight extenders.
- Reduces hydrostatic pressure on weak or depleted formations.
- Helps minimize formation breakdown and lost circulation risks.
- Compatible with a wide range of oilfield cement systems.
- Chemically inert and stable under typical cementing conditions.
