Manage Contamination and Protect Fluid Performance With Hydrated Lime From Di-Corp
Hydrated lime, also known as calcium hydroxide or slaked lime, is a dry powder used to raise pH in various industrial applications, including clear water drilling. It is produced by reacting quicklime with water.
In clear water drilling, hydrated lime is added to sump water to increase the pH and provide calcium ions. In a Gyp-based mud system, hydrated lime is added at a concentration of 1.0 kg/m³ and then used as needed to maintain a pH of 10.0-11.0 in the drilling fluid.
Hydrated lime is also used to adjust alkalinity when bicarbonate/carbonate contamination exists. In oil-based drilling fluids, it helps maintain alkalinity, enhance emulsifier performance, and provide a degree of corrosion protection.
