Abstract:
A method for treating an oil-bearing subsurface formation is disclosed that includes providing one ore more acid soluble materials into a wellbore in the oil-bearing subsurface formation. The wellbore may include a plurality of first perforations in the wellbore that have been used to form first fractures emanating from the wellbore in the formation. The acid soluble materials may be used as a diverting agent to form plugs in existing perforations in the wellbore. The plugs may inhibit fluid flow through the existing perforations. The plugs may be removed at any time desired by providing an acid into the wellbore or by incorporating a delayed source of acid in the diverting agent.

Claim (Index 41):
A method for treating an oil and gas-bearing subsurface formation, comprising:\n providing a mixture of one or more acid soluble materials and a delayed source of acid into a wellbore in the oil-bearing subsurface formation, wherein the wellbore comprises a plurality of first perforations in the wellbore used to form first fractures in the formation emanating from the wellbore in a hydraulic fracturing process, and wherein at least one of the acid soluble materials and the delayed source of acid combine to form a plug in one or more of the first perforations, the plug inhibiting fluid flow through such first perforations; forming one or more second perforations in the wellbore; and allowing the delayed source of acid to form acid in the wellbore, wherein the acid removes the plugs formed by the at least one acid soluble material and the delayed source of acid.
