Abstract
In a relatively weak water-wet gas-producing reservoir in which a liquid tends to impair the gas production, the rock strength is increased by injecting a silicon polyhalide vapor, such as silicon tetrachloride vapor, mixed with a relatively inert gas, so that the silicon halide converts the rock-wetting water to a rock-strengthening silica gel.
