Diacel® Adjustable Spacer ​Diacel® Adjustable Spacer System Viscosifier Additive is a proprietary blend designed to provide fluid loss control and viscosity allowing users to easily formulate a spacer with the desired rheology and density.
DIACEL® ATF Liquid Cement Antifoam Additive A liquid anti-foaming agent for cement slurries, designed to prevent air entrapment in the slurry during mixing.
Diacel® ATF-S Liquid Cement Antifoam Additive Diacel® ATF-S Liquid Cement Antifoam Additive is a silicone based liquid antifoaming agent for cement slurries, and it is compatible with all commonly used cement additives.
DIACEL® D Powder Cement Extender Additive A special grade of refined diatomaceous earth that permits the formulation of high-yield, low-density cements.
DIACEL® FL Powder Cement Fluid-Loss Additive A non-retarding fluid-loss agent effective from 21ºC to 232ºC bottom-hole circulating temperature.
DIACEL® FL Winterized Liquid Cement Fluid-Loss Additive A non-retarding fluid-loss agent effective from 21ºC to 232ºC bottom-hole circulating temperature.
DIACEL® HE-400 Powder Cement Fluid-Loss Additive A versatile synthetic polymer for anti-settling and fluid loss control properties at high temperature in oilfield cement slurries and spacers.
DIACEL® HTP-1500 Powder Cement Fluid-Loss Additive A mildly retarding powder fluid-loss agent effective in mid-range to high temperatures.
DIACEL® HTR-100 Liquid Cement Retarder Additive An upper mid-range to high temperature retarder in liquid form which has dispersing properties and is blended with the cement to extend the thickening time of a slurry. It also improves the performance of most fluid-loss agents.
DIACEL® HTR-100 Powder Cement Retarder Additive An upper mid-range to high temperature retarder in dry powder which has dispersing properties and is blended with the cement to extend the thickening time of a slurry. It also improves the performance of most fluid-loss agents.
DIACEL® LTP-1000 Powder Cement Fluid-Loss Additive A mildly retarding powder fluid-loss agent effective in low- to mid-range temperatures.
DIACEL® LTR-100 Liquid Cement Retarder Additive A low-temperature retarder in a liquid form used to extend the fluid life of the cement slurry.
DIACEL® LTR-100 Powder Cement Retarder Additive A low-temperature retarder in a dry powder used to extend the fluid life of the cement slurry.
DIACEL® LWL Powder Cement Fluid-Loss Retarder Additive A bi-functional additive that is effective both as a retarder and fluid-loss control agent over a wide temperature range.
DIACEL® LX200 Cement Fluid Loss Additive A latex filtration control agent for prevention of gas migration in cement slurries to 200º F BHCT without the use of a stabilizer.
DIACEL® RPM Liquid Cement Dispersant Additive A rheological profile modifier in liquid form that may be used to promote turbulent flow at reduced flow rates.
DIACEL® RPM Powder Cement Dispersant Additive A rheological profile modifier in a dry powder that may be used to promote turbulent flow at reduced flow rates.
DIACEL® WBS-200 Powder Cement Spacer System A special mixture of amorphous silica and water-soluble polymers for use in the preparation of a water-based cement spacer for the separation of water-based drilling fluids and cement slurries.
