SELECTIVE RESTORATION OF FLUID COMMUNICATION BETWEEN WELLBORE INTERVALS USING DEGRADABLE SUBSTANCES

摘要

A method of removing two or more isolation devices comprising: introducing the two or more isolation devices into a wellbore, wherein the wellbore comprises at least two wellbore intervals, wherein each isolation device comprises a substance, wherein each of the substances degrades within the wellbore, and wherein the degradation rate of each of the substances causes fluid communication to be restored between the wellbore intervals in a desired amount of time; and causing or allowing each of the substances to degrade.
