Solid WireIine

Definition - What does Solid WireIine mean?

Solid Wireline is the cabling system which helps the rig operators to lower down equipment, wireline tools, or measuring devices into a wellbore. A solid wireline consists of braided cables which are used for pipe recovery, evaluation purposes, well intervention or maintenance. It also contains electrical cables which are used to check the well condition of the wellbore. The data received is logged into wireline logs.

Petropedia explains Solid WireIine

On a wireline, wireline tools which are specifically designed instruments for well workover functions are used. The solid wireline is helpful in taking down and bringing up any type of instrument in and out of the wellbore. The wireline tools and other devices which are fed into the wellbore with the help of a solid wireline are useful 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 hard conditions, modern wireline tools are used to withstand these extreme conditions. In the gas wells, 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 Solid wireline and wireline tools should be strong enough such that they can withstand these rigorous temperatures and pressure.

The solid wireline comes in the diameter sizes of 0.092", 0.108", 0.125", 0.140", 0.150", and 0.160" and are generally 18000, 20000, 25000 and 30000 foot long.
