What is claimed is:
1. A method of stimulating a subterranean formation penetrated by a reservoir, the method comprising: introducing into the reservoir a fluid comprising a biodegradable copolymer having the general formula of repeating units [—CHR—CH2—CO—O—] wherein R represents an alkyl group represented by CnH2n+1, and n is 1 and 3.
It is known in the art that hydraulic fracturing can be utilized to extract hydrocarbons from subterranean formations. There can be multiple potential producing zones within a single wellbore in a subterranean formation to be fractured. Often times, it is desirable to isolate these zones from one another to divert...
