  • Patent number: 8960292
    Abstract: A method of servicing a wellbore comprising inserting a first tubing member into the wellbore, wherein a manipulatable fracturing tool is coupled to the first tubing member and comprises one or more ports configured to alter a flow of fluid through the manipulatable fracturing tool, positioning the manipulatable fracturing tool proximate to a formation zone, manipulating the manipulatable fracturing tool to establish fluid communication between the flowbore of the first tubing member and the wellbore, introducing a first component of a composite fluid into the wellbore via the flowbore of the first tubing member, introducing a second component of the composite fluid into the wellbore via an annular space formed by the first tubing member and the wellbore, mixing the first component with the second component within the wellbore, and causing a fracture to form or be extended within the formation zone.

  • Publication number: 20100200230
    Abstract: Methods of treating a well bore in a single trip are provided. A tubing string may be inserted into a subterranean formation having a well bore, where the tubing string has a locking device on an end. A workover tool may be positioned in a first zone of the subterranean formation, where the workover tool engages the locking device. One or more perforations may be created or enhanced in a first zone of a subterranean formation using the workover tool, and the tubing string may be positioned in a second zone of the subterranean formation. A fracturing fluid may be introduced into the first zone of the subterranean formation at a rate and pressure sufficient to create or enhance one or more fractures in the subterranean formation. The first zone of the subterranean formation may be isolated from the second zone of the subterranean formation and one or more perforations in the second zone of the subterranean formation may be created or enhanced using the workover tool.
