FLOSS 110 Fluid Loss Control Additive and Viscosifier for Well Cementing
Oil Energy product grades: LV - low viscosity; MV - medium viscosity; HV - high viscosity
Product description
FLOSS 110 is a fluid loss control additive and viscosifier for cement slurries and spacer systems. Product effectively reduces fluid loss in fresh-water and salt-saturated cement systems.
The product is primarily used in well cementing operations as a thickening and water-retention additive. It affects cement slurry viscosity, helps stabilize the system and is suitable for preparing weighted spacer compositions.
Physical Properties and Chemical Composition
FLOSS 110 is based on cellulose ethers and is available in grades with different viscosity levels: low-viscosity (LV), medium-viscosity (MV), and high-viscosity (HV).
Benefits
- -1-Reduces free-water separation; the high-viscosity HV grade is recommended for lightweight cement slurries
- -2-Improves sedimentation stability by increasing slurry viscosity
- -3-Retards cement slurry setting time, which can be beneficial at elevated temperatures
Application and Dosage Recommendations
- The product performs effectively at temperatures from 0 to 110 °C.
- For lightweight cement slurries, use FLOSS 110 HV at 0.2–0.6% BWOC.
- For normal-density cement slurries, use FLOSS 110 HV at 0.04–0.15% BWOC, FLOSS 110 MV at 0.05–0.3% BWOC, or FLOSS 110 LV at 0.1–0.4% BWOC.
- FLOSS 110 HV may be used at 0.2–2.0% BWOC as a component of a separating spacer composition, where it stabilizes and thickens the system and provides high sedimentation stability.
- The additive can be introduced into the dry cement blend or into the mix water.
Packaging and Storage Conditions
FLOSS 110 is supplied in 25 kg bags. 40 bags are placed on one pallet.
Store the product in closed, undamaged packaging in covered, dry warehouse facilities, away from heating devices and sources of moisture.

Q&A from Oil Energy Experts
Q&A from Oil Energy Experts
Synthetic fluid loss control additives, such as FLOSS 500 and FLOSS 600, are copolymers designed for demanding conditions, including high temperatures and applications where minimal impact on cement slurry rheology is required.
FLOSS 110 is a cellulose based additive that provides water retention and thickening. It dissolves well in water and is resistant to salts of multivalent ions, but it has a greater effect on cement slurry viscosity and may extend setting time.

Different cement slurry rheology and viscosity requirements call for different FLOSS 110 grades. The low viscosity LV grade is suitable where minimal impact on rheology is needed. The medium viscosity MV and high viscosity HV grades are used where improved water retention and system stabilization are required.
The product range includes grades with different molecular weights and degrees of substitution, allowing the additive to be selected for specific well conditions and cement slurry formulations.

The temperature limit of a fluid loss control additive depends on its chemical basis. Synthetic products such as FLOSS 600 can be used at temperatures up to 200°C. Cellulose based additives generally have lower thermal stability because of their cellulose ether structure.
FLOSS 110 is recommended for applications at temperatures not exceeding 110 °C. At higher temperatures, it can be combined with a synthetic fluid loss control additive in the cement slurry formulation.
