Abstract
A method for performing a service operation within a wellbore extending into a formation comprises sealing a first length of the wellbore to define a first isolated formation zone, flowing a pressurized fluid through a tubular string into the first isolated formation zone, and unsealing the first length of the wellbore without venting the pressurized fluid from the tubular string or awaiting depressurization of the first isolated formation zone. An assembly connected to a tubular string for performing a service operation in a wellbore comprises a mandrel with a flowbore in fluid communication with the tubular string, an upper sealing device, a lower sealing device, a selectively operable valve that enables or prevents fluid communication between the flowbore and the wellbore, and a selectively closeable bypass flow path.
