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

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.

A depth control system for maintaining a tubing conveyed tool in a desired location in a cased wellbore during wellbore operations performed with the tool includes a bottom hole assembly carried by a tubing, the bottom hole assembly including a tool and an anchoring device. A method for maintaining a tool at a desired depth in a cased wellbore while performing wellbore operations with the tool includes the steps of conveying a tool and an anchoring device on a tubing to a desired depth in a wellbore having a casing, operating the tool to perform a wellbore operation and actuating the anchoring device to engage the casing and maintain the tool at the desired depth.
