  • Method and system for treating a subterranean formation using diversion
    Patent number: 8646529
    Abstract: A method of well treatment includes establishing fluid connectivity between a wellbore and at least one target zone for treatment within a subterranean formation. The method includes injecting a treatment composition into the wellbore. The method includes contacting a subterranean formation with the treatment composition, providing a diversion agent to a desired interval in the wellbore and measuring a wellbore parameter while performing at least one of the contacting the target zone and the providing the diversion agent.

  • Method and system for treating a subterranean formation using diversion
    Patent number: 8220543
    Abstract: A method well treatment includes establishing fluid connectivity between a wellbore and at least one target zone for treatment within a subterranean formation, which is intersected by a wellbore. The method includes deploying coiled tubing into the wellbore and introducing a treatment composition into the wellbore. The method includes contacting a target zone within the subterranean formation with the treatment composition, introducing a diversion agent through the coiled tubing to an interval within a wellbore and repeating the introduction of the treatment, the contacting of the target zone and the introduction of the diversion agent for more than one target zone.
