Fluid-Loss Control Additives
high-temperature-resistant-starchHigh Temperature Resistant StarchA fluid-loss control additive made from chemically modified natural starch, combining excellent high-temperature stability with an environmentally friendly profile. It regulates mud rheology and protects wellbore stability in high-temperature drilling, making it well suited to deep and ultra-deep oil and gas wells.Fluid-Loss Control AdditivesPAC-141 / 142 / 143Multi Copolymer Pac 141 142 143PAC-141, PAC-142 and PAC-143 are anionic multi-copolymers of vinyl monomers such as acrylic acid, acrylamide and sodium acrylate. Non-toxic, non-corrosive and readily water-soluble, they deliver excellent fluid-loss control with temperature resistance up to 180 °C and salinity tolerance up to saturation, making them ideal for low-solids non-dispersed polymer muds.Fluid-Loss Control AdditivesCMSCarboxymethyl Starch CmsAn anionic polymer derived from natural starch by etherification, CMS is an odorless white-to-yellowish powder that dissolves easily to form a viscous, transparent colloid. It provides fluid-loss control, viscosity building and shale stabilization in water-based muds, with good biodegradability for environmentally sensitive operations.Fluid-Loss Control Additivessulfonate-polymer-fluid-loss-additiveSulfonate Polymer Fluid Loss AdditiveA sulfonate-based water-soluble polymer fluid-loss control additive offered in low-, medium- and high-viscosity grades to match different drilling conditions. It optimizes filter cake structure through adsorption and bridging, delivering outstanding temperature and salinity resistance — including HTHP fluid-loss control after aging at up to 220 °C — with minimal impact on mud rheology.Fluid-Loss Control Additives
Encapsulators & Inhibitors
DS301Emulsion Polymer Encapsulator DS301DS301 is an anionic emulsion polymer encapsulator produced by inverse emulsion polymerization of acrylamide, potassium acrylate (KAA) and a cationic monomer. It adsorbs firmly onto cuttings to form a protective film that inhibits shale hydration and dispersion, with field-proven hole enlargement rates as low as 6.5%-8.8% in sloughing formations.Encapsulators & InhibitorsFA-367Encapsulator Fa 367FA-367 is a polymeric encapsulator that coats cuttings and clay surfaces with a tough protective film, stabilizing the wellbore and reducing hole enlargement. It improves mud rheology and filter cake quality, and tolerates salts, calcium/magnesium ions and temperatures above 180 °C.Encapsulators & Inhibitorsamine-shale-inhibitorAmine Shale InhibitorA shale inhibitor formulated from novel amine derivatives. Its amine functional groups adsorb rapidly onto shale surfaces to form a dense protective film that blocks water invasion, effectively suppressing clay hydration, swelling and dispersion — with relative inhibition rates above 85% at ambient temperature and 90% after 150 °C aging.Encapsulators & Inhibitors
Viscosifiers & Rheology Modifiers
80A-51Viscosifier 80A 5180A-51 is a polymeric viscosifier with strong shear-thinning behavior that rapidly builds viscosity and optimizes rheology for cuttings suspension and transport. Compared with hydrolyzed polyacrylamide it provides better encapsulation and shale stabilization, and it is especially advantageous in solids-free fluids where formation damage must be avoided.Viscosifiers & Rheology Modifierspolyacrylamide-emulsionPolyacrylamide EmulsionA water-soluble, high-molecular-weight polyacrylamide emulsion for drilling fluids. Through adsorption and bridging on cuttings and wellbore surfaces, it improves viscosity, cuttings transport and wellbore stability in oil, gas and shale-gas drilling.Viscosifiers & Rheology Modifiers
