ABSTRACT:
A method of stimulating production of hydrocarbons from a well capable of production from oil and gas bearing strata wherein a desiccant is delivered through the well to dehydrate the well and a zone around it and then an anhydrous carrier for an anhydrous acidizing agent such as hydrogen chloride, hydrogen fluoride, or carbon dioxide is injected at a pressure sufficient for the gaseous materials to permeate through the strata and react with connate water to form a mixture of carbonic, HCl, or HF acids which will react with rocks forming the strata to increase the permeability of the strata and thereby stimulate production from the well.
