摘要: A dry cementitious composition which when slurried with water produces an economical hydraulic slurry for closing abandoned wells. The is a cement/CKD blend as the major component weight ratio of parts cement to CKD between about 2/3 and 3/1. Hydraulic slurries cured can produce hard bodies will meet or exceed API specification competent plug. process blending during transit from source off-load site without requiring further after off-loading. Methods are provided determining formulation having cheapest cost per unit volume thereby enabling competitive quotes based on cf required.
