Diacel® LWL Powder Cement Fluid-Loss / Retarder Additive is wide-temperature range additive that is dry blended with the cement powder prior to preparation of the cement slurry. Diacel® LWL Powder Cement Fluid-Loss / Retarder Additive is a bi-functional additive that is effective both as a retarder and fluid-loss control agent.
It can be used as a retarder on wells with bottom hole circulating temperatures (BHCT) of 150°F to 225°F. When used as a retarder, Diacel® LWL Powder Cement Fluid-Loss / Retarder Additive provides the additional benefit of improving the performance of other fluid- loss control agents. It can be used at BHCT less than 150°F by the addition of accelerators. At BHCT between 175°F to 225°F, Diacel® LWL Powder Cement Fluid-Loss / Retarder Additive can be used both as a retarder and fluid-loss control agent. Above 225°F, Diacel® LWL Powder Cement Fluid-Loss / Retarder Additive is used primarily as a fluid-loss control agent. The fluid-loss control performance of Diacel® LWL Powder Cement Fluid-Loss / Retarder Additive is improved when used in conjunction with dispersants and most retarders.
