Abstract:
A method for use in a wellbore, comprising:performing a gravel pack operation with a tool assembly in a section of the wellbore, the tool assembly attached to a tool string; providing a bypass mechanism in the tool assembly; actuating the bypass mechanism between at least a first position and a second position using a remote signal; maintaining communication of an elevated pressure through the bypass mechanism to the wellbore section to provide an overbalance condition in the wellbore section, the bypass mechanism communicating pressure from inside the tool string to the wellbore section if the bypass mechanism is in the first position, and the bypass mechanism communicating pressure from an annular region outside the tool string to the wellbore section if the bypass mechanism is in the second position; and initially setting the bypass mechanism to the second position prior to performing the gravel pack operation.
