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

In Summary
•Step Change in Perforating Safety
• Guaranteed shot detection
• Never return to surface with an armed gun
•Step Change in Data
• Data richness in standard configuration
• Will enable real time detailed analysis and job
records
All with the advantages of slickline conveyance to
better service operator needs
