A downhole tool, most commonly associated with slickline operations, that is used to open, close or shift the position of downhole flow control or circulation devices, such as sliding sleeves. The shifting tool generally features some means of engaging the components to be shifted and is typically run with upward or downward operating jars to deliver the necessary force or impact.
Industry:Oil & gas
A downhole valve assembly that is designed to hold pressure from above while allowing fluids to flow from below. Standing valves generally are run and retrieved on slickline with the valve assembly located in an appropriate nipple. Applications for standing valves include testing the tubing string, setting packers, or other applications in which it is desirable to maintain fluid in the tubing string.
Industry:Oil & gas
A downhole tool, generally run on wireline or coiled tubing, that uses the detonation of a shaped explosive charge to cut the surrounding tubing or casing wall. The cutting action leaves a relatively clean cut surface, although the explosive action tends to flare the cut ends, making retrieval of cut tubular difficult if the fishing tool engages on the external surfaces.
Industry:Oil & gas
A downhole tool, generally run on slickline, used to remove paraffin and soft wax deposits from the internal wall of production tubulars and completion equipment.
Industry:Oil & gas
A downhole tool, generally run on slickline, that is used to open collapsed or damaged tubing. Configured with a tapered profile, the swaging tool acts as a circular wedge to force the tubing wall out as it is driven through a collapsed or restricted area. A jar is included in the tool string to provide the impact force necessary to push the swaging tool through the tubing restriction.
Industry:Oil & gas
A downhole tool with a profiled external surface designed to catch and retrieve junk or debris from the wellbore. The debris is carried up the tool-string annulus in the circulation fluid. An indented profile creating a larger annular area causes the fluid flow rate to drop and allows debris to drop into a basket or receptacle located at the base of the tool.
Industry:Oil & gas
A downhole tool used to repair the internal diameter of the production tubing where a slight collapse or a dent has occurred. Cutting profiles on a broach removes the tubing-wall material to allow subsequent passage of tools and equipment of a prescribed diameter.
Industry:Oil & gas
A downhole tool used with a jar to increase the impact force imparted as the jar is fired. Similar in function to an accelerator, intensifiers typically use compressed gas rather than a mechanical spring to store the energy released during operation.
Industry:Oil & gas
A downhole tool used to repair damaged or collapsed tubing. The tubing broach incorporates a cutter profile that is forced inside the tubing by jarring or hydraulic force to re-form the tubing wall by removing tubing wall material and forcing the tubing wall into place.
Industry:Oil & gas
A downhole tool used to pull or retrieve temporary plugs or similar equipment. The external pulling tool engages on the external surfaces of the item to be retrieved.
