Latexes

Gas migration can be controlled with a cement system that includes latex, stabilizers and dispersants. These latex systems can reduce fluid loss, increase acid resistance, and improve high-temperature suspension properties.   In general, latexes are colloidal in nature, with particles larger than a molecule, but smaller than grains of sand.  These particles also have a very large surface area.  As a result, the particles coagulate and deliver low permeability for a gas-tight cement sheath. Additionally, latexes enhance tensile and flexural strengths of the cement sheath.

Summary Summary Stabilizer 434C Latex Stabilizer
Stabilizer 434C latex stabilizer is a liquid material used with Latex 2000 cement to stabilize the latex in the cement slurry. The Latex 2000 system is a polymer emulsion and in the presence of salts, particularly divalent ions such as calcium, the latex tends to come out of emulsion, losing its effectiveness against gas migration in cement slurries. Stabilizer 434C latex stabilizer helps prevent the de-emulsification of Latex 2000 additive in cement slurries.
Summary Summary Stabilizer 434B Latex Stabilizer
Stabilizer 434B latex stabilizer helps prevent gas migration in Latex 2000 cement, a low fluid-loss cementing system. Latex 2000 cement is a water-internal, oil-external emulsion; in the presence of water, the system tends to come out of emulsion, losing its effectiveness against gas migration. Stabilizer 434B latex stabilizer helps prevent the de-emulsification of Latex 2000 cement.

Summary Summary Halad-400L Fluid Loss Additive
Halliburton’s Halad®-400L fluid loss additive is a synthetic additive developed for temperatures from below 80°-400°F (27°-204°C) and for salt concentrations from zero percent to saturated salt concentrations. Halad-400L has been environmentally approved for use in the North Sea (exhibits biodegradability, low toxicity, and low bioaccumulation potential). This additive works without building viscosity and has a slightly dispersive character, thus the cement slurry remains thin. This additive is available as an aqueous liquid with a 22% activity.
