Digital Trigger: Safe, On-Demand, Efficient and Recordable Perforating on Slickline

2012 International Perforating Symposium - Europe

Slickline Services 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
