Patent number: 7861774Abstract: A tubing string assembly is disclosed for fluid treatment of a wellbore. The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off. The tubing string can also be used where a ported tubing string is required to be run in in a pressure tight condition and later is needed to be in an open-port condition.Type: GrantFiled: May 22, 2009Date of Patent: January 4, 2011Assignee: Packers Plus Energy Services Inc.Inventors: Jim Fehr, Daniel Jon Themig
