Web13 mei 2024 · Shale inhibitor is an additive for drilling fluids that can be used to inhibit shale hydration expansion and dispersion, and prevent wellbore collapse. Small molecular quaternary ammonium salt can enter the interlayer of clay crystal, and enables an excellent shale inhibition performance. WebA shale inhibitor can limit water entry through two primary mechanisms. One is when the cation present is exchanged for one that can increase the attraction between clay platelets, limiting entry of water. Typically this method includes adding salt, such as potassium chloride, to the base fluid. Another mechanism, commonly referred to as ...
WebNaCl/ 3-5% KCl polymer mud was selected to drill intermediate and production sections such as the rest of 17 ½" section, 12 ¼", 8 ½" and 6" sections to inhibit shale formations presented in these sections. High performance water base drilling fluids were selected because of the problems ...
Web9 aug. 2024 · The inclusion of salts in injected water (called low-salinity water) is considered successful to inhibit shale swelling. Therefore, this study reports the impact of shale content (0–25%) on porous and permeable sand-packs in the presence of fresh water and salt solutions (KCl/CaCl2, 0–4 wt%). easy hispanic recipes for kidsWeb3 feb. 2024 · KCl and org. quaternary amine 2,3-epoxypropyltrimethylammonium chloride in all tests.
