Abstract:
Disclosed is an improved apparatus and method for performing downhole operations to a subterranean formation while isolating the formation from the remainder of the well bore. The invention utilizes a tool assembly which initially sets a packer above the formation while allowing a downhole tool to extend through a passageway in the packer to perform operations such as perforating the formation. The assembly permits retrieval of the tools through the passageway in the packer while sealing off the formation from the remainder of the well.
