Abstract
Methods of forming one or more plugs in a well bore are provided. The methods basically comprise the steps of dropping into the well bore a cementitious material which will delayedly react with water therein to form an impermeable solid and which has been formed into agglomerates of sufficient weight to sink through the water and other fluids and materials in the well bore. The agglomerates are dropped in a quantity sufficient to form a mass of the agglomerates in the well bore. Thereafter, the mass of agglomerates is allowed to react with the water in the well bore and set into an impermeable solid plug therein.
