Cement Additive Oilfield Glossary Schlumberger
well completions chemicals and materials added to a cement slurry to modify the characteristics of the slurry or set cement. cement additives may be broadly categorized as accelerators, retarders, fluid-loss additives, dispersants, extenders, weighting agents, lost circulation additives, and special additives designed for specific operating conditions.smart cements and cement additives for oil and gas operations. simply controlling the chemistry involved in the type of layered inorganic material, charge thixocrete lightweight lost circulation cementing solution combines lightweight high-performance trimodal cement and a thixotropic additive to rapidly deliver high gel strength and compressive strength. the trimodal cement contains an optimized particle size distribution that maximizes solids content and plugging efficiency.
