摘要： A perforating gun can be conveyed on tubing and fired while disconnected from the tubing. The gun is retained to a running tool at the lower end of the tubing in a locked position. Actuating a plunger by pressure, a weight bar or other techniques, breaks a rupture disc and allows use of hydrostatic pressure to stroke a piston and defeat the lock between the gun and the running tool. Upon exposure of ports on the gun to wellbore hydrostatic due to movement out of the running tool, the firing sequence in the gun is initiated. The weight of the gun, as well as hydrostatic or applied pressure in the wellbore, drives the perforating gun out of the running tool.

摘要： A running tool is disclosed to deliver tools downhole, preferably supported on a wireline. The running tool will not release the downhole tool before the desired depth is reached, even if an obstruction is encountered. The tool has the ability to release upon application of pressure in the wellbore. The tool features a floating piston with a pre-charged chamber on one side. Hydrostatic pressure acts on the opposite side of the floating piston as the running tool descends. When the downhole tool reaches its desired depth and becomes supported, slacking on the wireline traps the hydrostatic on one side of the floating piston. Applied wellbore pressure, acting on a release piston exposed to the trapped hydrostatic on its opposite side, shifts the release piston and releases the running tool from the downhole tool. On the way uphole, the trapped hydrostatic pressure is released.

摘要： A one-trip system for placement and setting a downhole packer or plug is disclosed. The packer is settable in a variety of ways, including hydraulically, acoustically by pressure pulse signals, or some combination. Use of hydraulic pressure triggers a pressure-creating reaction to initiate the setting of the packer. The setting mechanism for the packer breaks clear of the packer upon setting and allows the tubing-conveyed perforating gun, which is already preassembled as part of the string, to be accurately positioned and fired.

摘要： A stackable thru-tubing perforating gun system for use in perforating in a large diameter cased wellbore below a smaller diameter production tubing string. The system comprises a thru-tubing retrievable bridge plug for supporting a lower perforating gun section. The system further comprises at least one additional gun section stacked on top of the lower gun section. After firing, individual gun sections may be retrieved from the wellbore through the tubing string.
