Web29 sep. 2015 · Finally, it was observed that a drilling fluid system comprising of KCl, Diamino Hexane and Bentonite was effective in reducing shale and Smectite swelling when … Webchange in shale volume, respectively. The results demonstrated that incorporating NPs into the KCL mud system enhanced shale inhibition. Adding NPs to the KCL-WBM increased yield point, plastic viscosity, and gel strength. The COF of KCL-polymer was reduced by 48% and 34% when added Al 2O 3 and Fe2O3 NPs at 0.5 and 0.75g, respectively. …

WebThis research suggests using Potassium Sorbate instead of KCl in drilling fluid to provide a chlorine-free, potassium-based drilling fluid which can stabilize water-sensitive shale … WebProduct Description. Potassium Chloride is chemically represented by the formula KCl and is also known by the name of muriate of potash. Potassium Chloride provides potassium ions to inhibit shale swelling and dispersion. It is used to drill the troublesome gumbo shales. Potassium Chloride is the most economical source of potassium ions.
WebClay and Shale Stabilisers assist inhibit clay, shales and silts. They prevent dispersion and minimize swelling that causes downhole problems, including stuck, bit balling and excessive mud weights. These products will improve core recovery and enhance drilling fluid integrity in difficult formations.
