The Collar Stop is designed to locate in the collar recess of API upset and non-upset tubing. By lowering the stop to the desired depth and lifting upward, the latch springs are tripped allowing the stop arms to expand into the collar recess. Downward jarring on the inner mandrel pushes it down behind the collar stop arms locking them into places in the collar recess.
The Tubing End Locator is used to determine the depth of the tubing through the use of a spring loaded finger. The spring loaded finger catches the end of the tubing, when pulled upward, registering a reading on the surface weight indicator.

The Wireline Stem, also called a weight bar, is used to add weight to the wireline toolstring to counteract the wellbore pressure, allowing the easy descent of the toolstring. It is also used to increase the effectiveness of jarring operations.
The Wireline Roller Stem is a tool used in the wireline workstring to minimize the effect of friction caused by the toolstring sliding on the tubing wall during wireline work in deviated wellbores.
Roller Stems consist of standard sinker bars with slots to accommodate simple rollers held in position with captive dowel pins.
The Knuckle Joint is designed for applications where toolstring rotation and/or deflection is required. It is most useful in fishing operations, where the pulling tool or overshot requires flexibility to properly locate the fish.
The Knuckle Jar provides a range of motion that helps to make the toolstring more flexible. Because the Knuckle Jar has a stroke, it can also be used for light jarring.
The Tubular Jar, through wireline manipulation, can be used to provide an upward or downward impact. The intensity of the jarring impact depends on the weight of the wireline stem above the jar, the stroke length of the jar, and the density of the well fluid. The perforated body of the Tubular Jar allows fluid bypass, reducing the effects of the well fluid density on the jarring impact.
Wireline Link Jars, sometimes called ‘Spang Jars’ or ‘Mechanical Jars’ are of the cable tool type, and utilize the weight of the stems connected immediately above, to deliver effective jarring impacts, by manipulating the wireline upwards or downwards at the surface. The effectiveness of these impacts is largely dependant on the weight of the stem used, the length of the stroke of the ‘jars’, the size and straightness of the tubing, the viscosity of the fluid in the tube, and the well pressure acting upon the cross sectional area of wireline. ‘Jars’ are composed of two pieces linked together, rather like long chain links, which are free to be extended or collapsed (stroke).
The Wireline Intensifier is a wireline stretch simulator device used in conjunction with hydraulic or spring jars when jarring at shallow depths in the wellbore. The wireline intensifier is available in sizes from 1-1/4” to 3” OD.
Upward tension, on the wireline compresses the spring, within the intensifier assembly and the stored energy, is transferred to the hydraulic or spring jars, located further down the toolstring.
A combination of surface wireline tension, and the energy stored within the spring of the accelerator, will eventually cause the hydraulic or spring jar to fire, thus completely releasing the energy stored within the spring. The tension of the wireline can then be relaxed and the operation repeated, until the subsurface tool is jarred free.
The Wireline Shock Absorber is used to dampen the shock transmitted to delicate downhole instruments being run into the wellbore during wireline operations.
The Wireline Shock Absorber basically consists of a fishneck, main body, upper spring, mandrel, lower spring and bottom sub. The lower spring is usually the heavier of the two springs, in that it is constantly compressed by the weight of the instruments, normally suspended immediately below the shock absorber. The mandrel floats between the upper and lower springs and absorbs shock; therefore, protecting the delicate downhole instruments.
The Paraffin Cutter (Gauge Ring) has many different purposes. It can be used to calibrate tubing, locate landing nipples, and remove paraffin and other deposits from the tubing wall.
The Blind Box is used to beat down an obstruction encountered in the tubing string. It is also widely used to cut wireline on a rope socket during fishing operations. The Blind Box is approximately nine inches long with a male thread connection and fishneck facing upwards and flat bottom down. The diameter of the Blind Box should normally be matched to the tubing, in which it is to be used
The Pineapple Broach is used to cut burrs in the tubing I.D., caused by perforation, rust, bent tubing, etc.
The Tubing Swedge is used to bend out irregular places and other obstructions within the tubing string. It is equipped with a central bore and angled fluid ports, for ample fluid bypass.
The Fluted Centralizer is a wireline tool designed to ensure that the workstring running or pulling tool is at its most central position, especially during operations in deviated wells.
Normally attached to the toolstring just above the running/pulling, or fishing tool, the OD is machined to suit the ID of the tubing in which it is to be run. This allows the tool to be used as a tubing drift, or gauge in addition to centralizing the toolstring.
The Bow Spring Centralizer is designed for use with slickline toolstrings, or when running downhole gauges out through the tail pipe and into the casing.
The Bow Spring Centralizer is able to pass through the restricted bores of the tail pipe and expand into the casing liner below, thus enabling the tools to be held away from the casing.
The Sand Bailer is a pump action type bailer, designed to remove sand and small debris in the tubing string, through the upward stroking motion of the pump section. Sand and debris are held in the load barrel through the use of different style check bottoms. A large percentage of wireline service involves sand bailing, prior to the actual pulling or setting of subsurface flow controls.
The Dump Bailer is designed to allow a variety of fluids to be dumped within the well, on top of any sub-surface device. Wireline Dump Bailers are available in a variety of sizes. The bottom shoe of the Wireline Dump Bailer should always be matched with the downhole device, upon which fluid is to be dumped. Bottom assemblies are available with glass shear disc or O-Ring seal piston.
The Go Devil is dropped to cut the wireline at the rope socket, when the toolstring becomes stuck.
The Wirefinder Split Skirt is used to bend or ball the uppermost part of the wire, so that retrieving applications may be used.
The Center Spear is made by welding barbs on a pointed rod. It is most commonly used when the wire is balled up and stuck in the tubing. It can be driven into the tangled wire to loosen it and facilitate the use of a two prong wire grab for final wire retrieval.
The Two Prong Wireline Grab is used to retrieve broken wire from the tubing string. The arms include welded bards, which catch the wire.
The ‘Baiting’ Type Bulldog Spear is used to retrieve (fish) wireline tools lost in the wellbore that do not have a conventional fishing neck and are therefore, best fished with an internal spear.
The spear is run on a ‘GS’ running/pulling tool and speared into the fish. In the event the fish cannot be pulled, the ‘GS’ running/pulling tool will shear its pin and release. This will leave an internal fishing neck ‘looking up’, to enable further fishing attempts. The fish is then said to be baited.
The ‘Baiting’ Type Bulldog Spear has an optional Engagement Stop Ring (shown) available on request.
The Releasable Overshot is a slip type overshot, used to retrieve a fish lost in the wellbore that does not have a conventional fishing neck.
Once latched onto a fish, the overshot can be released by jarring downwards provided the overshot has a solid footing upon which the core can be driven against.
The Heavy Duty Magnet Fishing Tool is a wireline service tool used to magnetically attract and retrieve ferrous debris lost in the wellbore.
The Impression Block consists of a steel housing with a lead insert. Impression Blocks are used during fishing operations to determine the shape, size and position of the object being fished.
