Physical property comparison of polymeric KCl sludge composition and polyamine at different temperatures

Abstract

Abstract Drilling mud is a fluid used to assist the drilling process. The composition and physical properties of the mud greatly influence a drilling operation. Drilling operations that penetrate formations with shale content have the potential to experience drilling problems related to shale hydration. To get a good ability to prevent shale hydration, mud is added with polymeric and polyamine KCl additives (shale inhibitors) with the aim of stabilizing shale in contact with drilling fluid, as well as preventing drill cuttings from forming colloids. The results obtained in the KCl polymer mud composition at temperatures of 80°F, 250°F, and 300°F for mud weight were 9.3 ppg, 9.1 ppg, and 9 ppg, respectively. Funnel viscosity was 40 sec/qt, 36 sec/qt, and 34 sec/qt. Tap rates were 4.8 cc, 6 cc, and 6.6 cc. Mud cake remained at 1 mm and pH also remained at 9. While the results obtained on polyamine mud composition at temperatures of 80°F, 250°F, and 300°F for mud weight were 9.2 ppg, 8.9 ppg, and 8.8 ppg, respectively. Funnel viscosity was 26 sec/qt, 20 sec/qt, and 17 sec/qt. Tap rate of 10 cc, 13.8 cc, and 15 cc. Mud cake of 1 mm, 2 mm, and 2 mm. pH remains at 9. The data obtained shows that the results of the physical properties of polymeric KCl mud are better than polyamine mud.
