Abstract:
The present invention provides a methodology and compositions for re-fracturing a wellbore. By differentiating existing perforations that have been fractured from those that are not, applying a sealing composition to seal off the identified, fractured perforations, and performing re-fracturing to perforations that are not sealed, a wellbore can be re-fractured effectively and efficiently. The present invention for re-fracturing a wellbore has broad applications in the field of hydraulic fracturing.
