The Importance of Wireline and Wireline Tools

Wireline is a cable used to transport downhole tools and sensors. The benefit of using wireline is that it almost always delivers results on the spot and allows for electricity and data to be transferred between the surface and the equipment in the well. Western Pressure Controls manufactures tools to use with wireline, including fishing, shifting, and pulling tools.


It’s important to keep your equipment clean, especially when you’re using it to fish out objects that don’t belong in the well. Wireline is used for a myriad of tests, so by using the proper cleaning procedures before, during, and after use, you will prolong its life and durability.

Residual fluids, mud, and sediment will affect the wireline whether it’s been used in a dry well or a wet one. It should be greased and protected from the weather with Densyl tape when the wireline is in use, particularly on a winch.

Storing wireline in a dry and safe place does not ensure its good condition. It can deteriorate, so it must be thoroughly checked on a regular basis, which includes unspooling it. If consistent checks are not performed, you could end up losing a costly purchase since wireline is made from a high alloy geared for its specialized tasks.

Stuffing box packing, a tool that contains well pressure, helps clean off well fluids from the wireline as it passes through the stuff box packing. It is still necessary, however, to clean off the wireline again and to grease it if you are still using it.

The Oil and Gas Industry

The oil and gas industry, a global powerhouse that produces billions of dollars, is broken into three areas: upstream, midstream, and downstream. Wireline tools are only used for the industry’s upstream area (also known as the exploration and production sector of the petroleum chain) to drill in old wells or to create new ones. Wireline tools assist workers in recovering oil and gas.

Wireline tools and equipment endure some of these types of tasks:

  • Perforating to facilitate circulation to the annulus
  • Recovering unwanted objects or broken pipes
  • Locating free space when pipes are stuck
  • Evaluating pressure formation present in the well

Locking Mandrels From Western Pressure Controls

Locking mandrels are essential for the safe operation of any wireline operation. A lock mandrel is a cylindrical device that is placed inside a tube to act as a setting point for flow-control mechanisms like plugs and valves. A properly functioning and high-quality lock mandrel ensures that your wireline operation goes as smoothly and efficiently as possible. Here is some more information about a few of the most popular locking mandrels available from Western Pressure Controls.


S-Lock With Keys

 One of the most common locking mandrels is the s-lock. S-locks are designed to be run on a C-1 running tool. The S-lock from Western Pressure Controls has both upward and downward facing dogs that prevent movement once locked into place. This device is available in a variety of sizes ranging from 1.5 inches to 3.5 inches.


W and Z Locks

 These devices are equipped with a set of dogs that lock into place and prevents any movement. The W lock downward movement is prevented by a mechanism on the lock body, while the The Z lock downward movement is prevented by a locking mechanism on the equalizing assembly. This devices come in a standard size of 2.5 inches, and come with keys to unlock the devices.


D Locks

Another popular style of locking mandrel is the Otis-style D lock. The D lock is placed and locked into an API tubing collar to retain a pressure differential from above and below. The sealing element is mechanically locked in the collar and can be used in conjunction with pump thru valves, standing valves, or choke assemblies. The D locks for Western Pressure Controls are outfitted with a knockout kobes to equalize pressure differentials.
