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
Telemetry Enabled SlicklineStandard core
Sandvik 0.108” and 0.125” 5R60 Stainless Steel
Temperature range -40 C to 150 C (-40 F to 302 F)
Pressure range 0 - 10,000 psi Breaking strength 1870 lbs
(108) and 2500 lbs (125)Insulation Specification
Proprietary polymer compound
Non reactive, H2S resistantSour Service Cable
Sanicro H2S cable available
