LIME, hydrated Lime is the common name for calcium hydroxide [Ca(OH)2]. It is used as a source of calcium and alkalinity in both water and oil-base drilling fluids. Drilling fluid applications for LIME include: increasing pH; providing excess LIME as an alkalinity buffer; flocculating bentonite muds; removing soluble carbonate (CO3-2) ions; controlling corrosion; and activating fatty-acid, oil-base mud additives.
- Lime is used as an economical source of calcium for flocculating bentonite slurries for improved hole cleaning in spud muds.
- Excess Lime buffer pH, provides a reserve quantity of calcium to precipitate soluble carbonates.
- An alkaline pH which is buffered by excess Lime will prevent acidic conditions from occurring which can lead to accelerated corrosion from acid gasses.
- Lime precipitates soluble carbonate ions.
Low-Lime 0.5 to 2.0 lb/bbl
Medium-Lime 2.0 to 5.0 lb/bbl
High-Lime 5.0 to 15.0 lb/bbl
Water-base: Excess Lime (lb/bbl) = 0.26 [Pm – (Fw x Pf)]
Oil-base: Excess Lime (lb/bbl) = POM x 1.3
