Slick Line Services

• Tagging T.D. (Total Depth, which is the furthest depth possible down the wellbore).

• Gauge Ring runs (which is running a special sized down hole tool called a gauge ring, which comes in various pre-machined diameters, designed to ensure the pipe is clear to a certain point).

• Tubing Broach / Plunger Installations (a tubing broach looks like an aggressive, tubular file, available in different diameters, used for removing burrs and crimps in the inside of tubing and casing in oil and gas wells).

• Bailing sand and debris (removing formation sand/rock and other such debris left over from the drilling and completion of the well, using a specialized tool called a bailer. This tool uses either a Chinese water pump type stroke action or a hydrostatic vacuum action to suction up the down hole debris, allowing it to be conveyed back to surface via the wireline).

• Shifting sleeves, (formations down hole can be isolated behind sliding metal ‘windows’ called sliding sleeves. They are shifted open or closed by means of a specialized shifting tool locating the sleeve and it being jarred up or down, providing access or closing off that formation or section of casing).

• Setting / Pulling plugs and chokes (specialized down hole tools which either lock into pre-machined restrictions in the tubing, or which lock into the tubing itself, sealing pressure from below or above the plug).
• Setting / Pulling gas lift valves.

• Running tailpipes (tubing extensions where the tubing is not landed close enough to the formation perforations in the casing).

• Bottom hole pressure and temperature surveys (specialized electronic and mechanical tools designed to measure the pressure and temperature at predetermined depths in the wellbore. This data can be used to determine reservoir life).

• Spinner Surveys (to determine which formation perforations have the best inflow / which perforations make the most water / liquids).

• Kinley perforator, sandline cutter, and caliper.

• Running production logging tools.

• Fishing operations (fishing usually refers to attempting to retrieve lost tools or wire, or other debris that was not intended to restrict the flow / disrupt the well operations. Fishing can be difficult, due the fish being down hole, and other affecting conditions such as high pressure, the fish being jammed in the tubing / casing).

• Paraffin cutting (making a hole through and removing a wax buildup, which is a byproduct of oil cooling too much to reach surface).

• Chipping ice / salt (restrictions and plugs which can be formed as by products of a flowing well).

• Lubricating long assemblies in and out of the hole (lubricating is done via a larger than tool overall diameter pipe, joined at surface on top of the wellhead, which houses the valve that shuts the pressure in downhole. The lubricator should be long enough to be able to swallow the toolstring.
