Digital Slickline Technologies – Controlled Release 4/1/2017 Digital Slickline Technologies – Controlled Release DCR digital controlled release tool controlled, on demand toolstring separation full cable removal internal and external fishing profile remains Automatic 24 hr programmable release Another key tool available to LIVE Act services, but also can be run with the full family of services, is the DCR. When the undesirable situation of the slickline toolstring being stuck downhole occurs, creating the possibility of cable breakage and a resulting fishing job, digital slickline can bring clarity and control to this predicament. When activated, this parting of the toolstring occurs in a controlled manner, leaving a known internal and external fishing profile downhole to facilitate subsequent fishing operations.

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
