The function of Wire Line unit is an integral part of the work-over and completions industry˳ It operations provide an economical means of regulating and controlling well fluid flow and clearing the tubing flow path of obstructions such as sand, scale, and paraffin˳
It is used for : Depth measurement, Temperature and pressure surveys (either static or flowing), Modification or regulation of the flow rate, Stopping or deviating the production, Separating different layers of formation, Opening and closing circulating ports, Tubing calibration, Removal of paraffin and cleaning of tubing in general, ˳ Bottom hole sampling, Tubing perforation˳
The fishing job is a job to removal of Wire Line tools that has been lost in the tubing while performing a wire Line operation˳ It is usually using special tools that are Cutter Bar, Side Wall Cutter, Kin Sniper, Go Devil, Wire Line Finder, and Impression Block˳
