ABSTRACT:
A system and method for simultaneously installing a pipe loop and a grout pipe in a wellbore has been invented which, in one aspect, is used to grout the wellbore by releasing the grout pipe from the pipe loop or from a bottom member connected with the pipe loop and then introducing grout through the pipe into the wellbore as the grout pipe is removed upwardly from the wellbore. In one aspect the system has a curved member or members or a ball or part thereof at the bottom of the pipes to facilitate movement of the system through a wellbore.
