ABSTRACT:
Improved method of and composition for the treatment of an oil-containing incompetent formation to prevent the movement of unconsolidated sand particles in an underground formation by forming a treating composition of sand, cement, silica flour and a sufficient amount of petroleum oil fraction containing an oil-wetting agent therein to oil-wet the sand, cement and silica flour particles suspending the resulting treating composition in an aqueous carrier medium, injecting the aqueous suspension against the unconsolidated formation at a pressure effective to force the treating composition into contact with the unconsolidated formation, contacting the placed treating composition with an aqueous curing solution to water wet the cement particles, permitting the cement to set and form a permeable cement and recovering oil through the cement.
