The benefits of Slickline conveyance

minimal footprint, logistical simplicity

operational efficiency

simplified well control and wire management

environmental friendliness

cost effectiveness

Inherent limitations

limited visibility and clarity of toolstring

actions and status

limited depth precision

limited capability

over dependence on slickline operator’s

experience level
