Imagine this Simple Scenario Punching Tubing for Well Recompletion
Real Time Data – Gulf Of Mexico, 6 ft of Strip Guns Punching Tubing Head Tension Pressure Temp CCL Shock Temperature drops as cooler annular fluids passes gun assembly Head tension increases 40 lbs after shooting gun and assembly yo-yo after shooting evident Pressure drops approx 140 psi after shooting. Yo-yo evident Shock of shooting gun clearly seen on accelerometer

Case Study: Bringing Wells Back Online • eFire and DSL Real Time Correlation Hybrid • Limited deck space and crane capacity • Two shut in wells • Shuttling operations to platform • Production restarted at 1000 bbls/d and 2700 bbls/d for each well
Field Data Shock detection when gun fired -120 g 20 psi increase in BHP 2 deg C increase in BHT ~80 lbs. drop in head tension ~10 lbs. drop in SURFACE tension

Case Study – Real Time Program Change • Control Reference Depth Downhole Tension Cable Vel Shot Detection • Confirmation Perforated Interval
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
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
