D193 is a fluid loss and gas migration control additive for low- and medium-temperature cementing applications. Diacel ® LX 200 Cement Fluid Loss Additive has a mild-retarding effect when used alone at BHCT < 125°F. The wide-temperature-range additive, part of the UNIFLAC universal fluid-loss additive system, is a custom-made liquid polymer that is less sensitive to small temperature or concentration variations. When mixed with Class H cement powder, water, a dispersant and defoamer, this non-ionic, low viscosity producing additive will prevent fluid from being lost to the formation in intermediate cementing operations. 10.9. Helps control fluid loss in environmentally sensitive areas between 125°F (51.7°C) and 300°F (148.9°C), acts as a mild retarder, gel breaker, and dispersant. But in oil well cementing, the used additives have limitations related to temperature, pressure and admixture property with other additives and cement.

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. Function: UFL-301 can enhance the viscosity of water phase in cement slurry and form aggregated chains of polymer in order to plug the pores in mud cake. Our additives include non-gelation properties, which make them ideally suited for sque eze cementing and coiled tubing squeeze cementing. This value is excessive for most cementing operations, where permeable formations are encountered or where long columns of cement will be used. Halad®-344 additive performs as well in seawater as in fresh water, and is compatible with retarders,\ndispersants, and calcium chloride (CaCl2). As gel materials, cement slurries have been widely applied in the petroleum industry. Halad-766 fluid-loss additive is extensively used to retard foam slurries without reducing viscosity. Because predictability of performance is typically the most important parameter in a cementing operation, considerable attention has been paid to mechanical control of slurry density during the mixing of the slurry to assure reproducibility. Developed as a less dispersive alternative to Halad-413 additive to meet response requirements in heavyweight slurries, seawater, and saturated salt designs. The design properties of slurries are significantly influenced by the water content. CFL 110 Powdered polysaccharide derivative. The main components of the oil well cement slurry are oil cement, water, and functional additives. This filter loss may be static or dynamic. These additives can be used across a wide range of design densities to extend the slurry, enhance stability, control fluid loss, and mitigate gas migration. Encapsulated fluid-loss additives for cement compositions (22) 21.07.2014 (43) 28.01.2016 (57) Disclosed are methods and compositions for cementing in a subterranean formation. SMLZ-108 is a non-retarding synthetic copolymer designed to control the loss of fluid from the slurry in porous environments. The tables below list the product specifications and part numbers for Halad-766 fluid-loss additive. Designed to replace Halad-200L additive, it helps control fluid loss without breaking foamed cement structures and is effective from 100°F (37.8°C) and higher than 400°F (204.4°C). DESCRIPTION . 426 fluid loss additives products are offered for sale by suppliers on Alibaba.com, of which petroleum additives accounts for 34%, electronics chemicals accounts for 2%, and paper chemicals accounts for 2%. It is a cellulosic fluid-loss additive for cement slurries.

Same is a requirement to design gas well slurries and. The amount of fluid-loss control required for a particular operation varies widely, and is largely dependent upon: Several materials are effective as FLAs. Insufficient fluid loss control can result in the cement slurry dehydrating and bridging off the annulus, preventing the slurry from being pumped to its final location and leaving excess cement in the casing. They can either be liquid or powdered additives. Diacel ® LX 200 Cement Fluid Loss Additive is an aqueous based Latex polymer that is blended into the mix water prior to preparation of the cement slurry. A fluid-loss additive designed for use in low-temperature wells (below 180°F or 82.2°C) to prevent retardation of compressive-strength development; acts as a dispersant as well. Expired - Lifetime Application number US06/615,394 Inventor Charles George Richard R. Gerke The cementing chemicals are the chemical agents dosed in the cement to ensure the smooth cementing operation and good cementing quality. On 30 th May 2020, BASF SE, a key player in the chemical industry, has confirmed that it plans to start its smart Verbund project in Zhanjiang, Guangdong.The first plants would manufacture engineering plastics and thermoplastic polyurethane to meet the increasing needs of diverse growth industries in the market across Southern China and across Asia. Section Links: Veritrol 343. Our advanced liquid and dry cementing latices enhance several key cementing properties, allowing for simpler slurry designs. UFL-73 A can control fluid loss through forming tight polymer film and enhancing viscosity of the water phase. Fluid loss additives, which are stable against high temperatures and concentrated salt solutions, ensure a reliable cementing job under difficult conditions. Thus, slurries that lose water can also be subject to a loss or degradation of design properties. In cementing operations, loss of the aqueous phase can severely affect the performance of the slurry and set cement. It is available as a powder or a 20%\nsolution (Halad®-567L additive). The water-soluble materials are modified natural polymers, cellulosics, and vinylinic-based polymers. Halad-766 fluid-loss additive is extensively used to retard foam slurries without reducing viscosity.
