What is the definition of wireline?
The term wireline usually refers to a cabling technology used by operators of oil and gas wells to lower equipment into the well for the purposes of a well intervention. In its simplest and most used form, the wireline simply consists of a single strand of metal wire most commonly 0.108″ or 0.125″ in diameter (sometimes referred to as slickline). In other cases, the wire will be composed of braided strands, rendering it stronger and heavier (called braided line). Braided line can contain an inner core of insulated wires which provide power to equipment located at the end of the cable (called electric line or E-line) and provides a pathway for electrical telemetry for communication between equipment at each end of the cable. The first use of wireline in a wellbore was as a measuring device. Measuring systems using rope or flat section steel tape, were over time replaced by wire.
