| titleOfInvention | Grouting composition and method |
| abstract | A grouting composition comprised of (a) 84-95 % by weight of granular sodium-based bentonite, (b) 1-8 % by weight of finely divided salt-water hydratable sepiolite, and (c) 4.8 % by weight of a clay stabilizer. The grout composition which contains no organic polymeric substances is mixed with fresh water to provide a pumpable rebydratable, and easily applied grouting slurry. The slurry admixture will form a solid seal with low hydraulic conductivity and high structural stability. The grouting composition is useful for scaling the annular space around a well casing and plugging abandoned wells in practically all types of formations. A preferred grouting composition comprises 88-90 % by weight of granular sodium bentonite, 6-7 by weight of sepiolite, and 4-5 % by weight of granular ammonium sulfate. In use, 50 pounds of the preferred grouting composition is mixed with 13-14 gallons of fresh water directly to provide a grouting slurry with a total of 30-32 % by weight of active solids and a density of 10.1-10.3 pounds per gallon. The slurry admixture is a completely inorganic non-toxic, and environmentally safe grouting system. |
