<p>A method of stimulating a flow of water into a well (10, 22) from water pools in strata surrounding the well (10, 22). The well (10, 22) is sealed in a manner such that pressurization of the well (10, 22) can be accomplished. Liquified carbon dioxide is introduced into the well (10, 22) at a down hole pressure such that the liquified carbon dioxide solidifies with the well (10, 22) forming solid carbon dioxide and introduction of the liquified carbon dioxide is continued into the well (10, 22) until a desired level of filling of the well (10, 22) is attained. The sealed well (10, 22) containing solid carbon dioxide is allowed to stand for a time sufficient to sublime the solid carbon dioxide contained in the sealed well (10, 22) and the residual pressure is released in the sealed well (10, 22) and the seal removed from the well (10, 22).</p> |
