The design properties of slurries are significantly influenced by the water content. Thus, slurries that lose water can also be subject to a loss or degradation of design properties. There are a number of conditions that can induce fluid loss:
•Water being drawn from the slurry into the permeable formation, in particular when pumping has ceased and the slurry is static, but not yet set
•Displacing or squeezing water from the slurry as it passes through constrictions such as tight clearance between the casing and the annulus
Fluid loss additives help operators retain the key characteristics of their cement slurries, including viscosity, thickening time, density and compressive strength development.
DeepFX™-L Additive
DeepFX-L additive: A single additive to provide fluid-loss control and shorten transition time to help address shallow water flow concerns.
Halad®-200L Fluid Loss Additive
Helps control fluid loss, viscosifies the slurry, does not retard the cement set, is salt-tolerant up to saturation, and is effective as low as 100°F (37.8°C) and higher than 400°F (204.4°C).
Halad®-23 Fluid Loss Additive
Helps control fluid loss, is effective in freshwater and saltwater slurries, is ideal for circulating jobs and for deep liner cementing, maintains fluidity, eliminates premature dehydration, and prevents bridging in a tight annulus when cementing is performed from 80°F (26.7°C) to 360°F (148.9°C).
Halad®-300L Fluid-Loss Additive
Designed to replace Halad-200L additive, it helps control fluid loss without breaking foamed cement structures and is effective from 100°F (37.8°C) and higher than 400°F (204.4°C).
Halad®-322 Fluid-Loss Additive
A fluid-loss additive designed for use in low-temperature wells (below 180°F or 82.2°C) to prevent retardation of compressive-strength development; acts as a dispersant as well.
Halad®-344 Fluid Loss Additive
Helps control fluid loss is non-retarding, and is compatible with freshwater and seawater.
Halad®-413 Fluid-Loss Additive
Provides excellent fluid-loss control in high temperature wells, especially when used on densified slurries or slurries with high salt concentrations due to its dispersing properties.
Halad®-567 Fluid Loss Additive
A fluid-loss additive made from synthetic polymer technology which is compatible with salt, seawater, and CaCl2 and effective up to 350°F (176.7°C) without over-retarding at temperatures as low as 80°F (26.7°C); it is not a strong dispersant so it can be used in normal and heavyweight slurries.
Halad®-600 LE+ Fluid Loss Additive
Helps control fluid loss in environmentally sensitive areas between 125°F (51.7°C) and 300°F (148.9°C), acts as a mild retarder, gel breaker, and dispersant.
Halad®-688 and Halad®-688 EXP additives
A fluid-loss additive similar to Halad 344 additive intended for use with construction grade or off spec cements.
Halad®-862 Fluid Loss Additive
Developed as a less dispersive alternative to Halad-413 additive to meet response requirements in heavyweight slurries, seawater, and saturated salt designs.
Halad®-9 Fluid Loss Additive
A blend of cellulose derivative and a dispersant developed for primary or squeeze operations between 60°F (15.6°C) and 300°F (148.9°C).
WaterWeb® Water Control
