ABSTRACT:
An unconsolidated gas-producing sand in which the permeability is layered and the productivity can be impaired by liquid blocking can be consolidated by wetting the rock surfaces with a limited amount of water, injecting a smoke which selectively reduces the permeability of the most permeable layers by depositing on their faces unconsolidated masses of substantially inert solid particles and injecting a gaseous silicon polyhalide to convert a significant proportion of the rock surface-wetting-water to a grain bonding silica gel.
