| DESCRIPTION - Fritz FL-7 is a powdered fluid loss additive recommended for blending with cement to control the loss of filtrate from a cement slurry.
ADVANTAGES
• FL-7 is a blend of a modified cellulose and dispersant used to control the loss of water from a cementing system when pumped or squeezed against a porous environment.
• It also functions as a cement retarder and may increase the viscosity of a slurry.
• It may be used in wells having bottom hole circulating temperatures from 60 to 250°F. (16 C to 121 C)
APPLICATION
• FL-7 may be used for fluid loss control in any API class of cement (A, C, G, or H).
• It may be used with other cement additives such as dispersants, silica flour, retarders, defoamers and weighting materials.
• FL-7 is not recommended for use in slurries with salt concentrations of 18% bww or greater.
