FC-610S Fluid loss Control additives
• FC-610S is a polymer fluid loss additive for cement used in oil wells that is created through copolymerization with AMPS as the main monomer and other anti-salt monomers. It has good temperature and salt resistance. The product has added groups that are difficult to hydrolyze, considerably improving the high temperature resistance. The presence of numerous highly adsorptive groups in the molecules, such as CONH2, SO3H, and COOH, is crucial for the molecules' ability to resist salt, maintain a constant temperature, absorb free water, and reduce water loss, among other properties.
• FC-610S has good versatility and can be used in a variety of cement slurry systems. It has good compatibility with other additives.
• FC-610S is suitable for wide temperature with high temperature resistance up to 230℃. After use, the fluidity of cement slurry system is good, stable with less free liquid and without retarding set and strength develops quickly.
• FC-610S is suitable for fresh water/salt water slurry preparation
High-temperature oil fields face a unique set of challenges when it comes to well cementing. One of these challenges is the issue of fluid loss, which can occur when the drilling mud filtrate invades the formation and causes a reduction in the fluid volume. To solve this problem, we have developed a specialized fluid loss reducer that is specifically designed for use in high-temperature oil fields. FC-610S is a kind of fluid loss control additive and it is suitable for Middle East market.

For more than 20 years, fluid loss control agents have been added to oil-well cement slurries and it is now recognized in the industry that the quality of cementing jobs has significantly improved. Indeed, it is generally clearly acknowledged that a lack of fluid loss control may be responsible for primary cementing failures, due to excessive density increase or annulus bridging and that formation invasion by cement filtrate may be deleterious to the production. Fluid loss additive can not only effectively control the fluid loss of cement slurry, but also prevent oil and gas layer from being polluted by the filtered fluid and thus increase the recovery efficiency.
