摘要：
The method of the present invention deploys controlled electrolytic material, CEM, into the existing perforations to seal them and then using a bottom hole assembly, BHA, that isolates a portion of the wellbore to deliver a material that removes the CEM at a predetermined rate so that the BHA can be used to refracture the recently opened perforation. Additional new perforations can be made and fractured during the process.
