Wireline Equipment

Definition - What does Wireline Equipment mean?

Wireline Equipment is a part of wireline-slickline equipment which consists of braided cables that are used for pipe recovery, evaluation purposes, well intervention and maintenance. The cabling system is used by operators to lower down wireline equipment and tools, or any other measuring devices into a wellbore. It also contains electrical cables which are used to check the condition of the wellbore. The data received from wireline equipment is logged into Wireline logs.

Petropedia explains Wireline Equipment

On a Wireline, Wireline equipment and tools are specifically designed for well workover functions on a well. The Wireline is helpful in taking down and bringing up any type of instrument in and out of the wellbore. These Wireline equipment and tools help in:

Evaluating rock properties in a reservoir
Pore size information gathering
Hydrocarbon formation pressure gathering
Location of casting collars
Sample recovery

Since oil and gas wells are drilled in locations with very harsh environmental conditions, modern Wireline equipment is made to withstand these extreme conditions. In the gas wells, the pressure can exceed 30,000 psi and in a geothermal well the temperature can be as high as 500 degrees Fahrenheit. So the material properties of the Wireline equipment and Wireline tools should be strong enough such that they can withstand these rigorous temperatures and pressure.
