Method for stimulation of liquid flow in a well

摘要

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