Document Type and Number:
WIPO Patent Application WO/2010/092352
Kind Code:
A3
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.
