Abstract
This invention relates to a method for treating wells completed in subterranean formations to form a mechanically stable, permeable mass which permits flow of fluids therethrough into or from the well, while restricting the movement of unconsolidated earth formation particles such as sand into the well. This method is especially suitable for treating producing wells in a subterranean formation being subjected to thermal oil recovery stimulation of viscous oil production such as by steam flooding, which causes rapid deteriation of consolidated sand or gravel masses formed with plastic resins. The method comprises contacting sand with an aqueous solution of calcium hydroxide, plus an effective amount of calcium salt having solubility greater than calcium hydroxide, such as calcium chloride, plus an alkalinity agent such as sodium hydroxide.
