Abstract: The present invention is a system for severing pipe. The system includes an explosively actuated pipe cutter, a pressure actuated initiator, and a means for suspending the cutter and the initiator inside the pipe and pressure sealing the interior of the pipe.In a particular embodiment of the invention, the initiator includes a time delay to enable reduction in pressure applied to the interior of the pipe for actuating the initiator.

Abstract: The present invention is a method and apparatus for inserting electric wireline tools into a wellbore using an apparatus comprising pipe assembled from sections and coiled tubing having a coaxially inserted wireline. The method includes the steps of attaching a first part of a submersible electrical connector to one end of the coiled tubing and to the wireline inside the coiled tubing. A second part of the submersible connector is attached to one end of the wireline tools. A first part of a selectively operable latching mechanism is attached to the same end of the wireline tools. A second part of the latching mechanism forms part of a latching sub which is attached to one end of the pipe. The tools are attached to the pipe by engaging the first and second parts of the latching mechanism, and the tools are inserted into the wellbore to a predetermined depth by assembling the sections of the pipe. The coiled tubing is then inserted into the interior of the pipe until the submersible connector is engaged.
