1 Matt Billingham Well Intervention Segment Technology Manager Digital Trigger: Safe, On-Demand, Efficient and Recordable Perforating on Slickline 2012 International Perforating Symposium - Europe

2 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 operators experience level

3 Telemetry Enabled Slickline Standard core Sandvik and R60 Stainless Steel Temperature range -40 C to 150 C (-40 F to 302 F) Pressure range ,000 psi Breaking strength 1870 lbs (108) and 2500 lbs (125) Insulation Specification Proprietary polymer compound Non reactive, H2S resistant Sour Service Cable Sanicro H2S cable available Telemetry NOT power

6 Historical Slickline Perforating No real time correlation Often requiring a parameter run Limited application

7 Explosive Device Operations - Requirements

8 Perforating SOP and Certification Path

9 Trigger Overview

10 D-Trig Safety Fuse

11 Dual Microprocessor Control

12 BMC Battery Level Activation

13 Telemetry Time Out* * D-Trig II 4 Hours

14 Electrical System Isolation

15 D-Trig Safety Sub

16 Safety Features – User Override for Fuse

17 Elimination of Conventional Detonators Can be used with Cat 4* EEDs/ detonators. Intrinsically RF safe No Primary High Explosives *SPE Insulating Header Match Compound Electric Match Primary High Explosive Output Explosive Bridgewire Primary High Explosive Output Explosive Bridgewire Output Explosive Insulating Header Slapper Secondary High Explosive Output Explosive Match/Fuse Detonator Solid Pack Detonator Exploding Bridge Wire Detonator Exploding Foil Initiator

18 Gulf Of Mexico – Eugene Island Block 71 Efficiency gains through multiple rig up/down, pressure tests saved with single conveyance Program: Drift (SL) Isolate C Sand Bridge Plug (eLine) 50 Cement Plug (SL) Perforate B Sand (eLine) Close out (SL) Depth accuracy critical therefore memory triggers not used Historically done with a combination of eline and slickline operations $80,000 estimated customer savings potential to use a smaller vessel

19 Real Time Data: Historical Shot Detection

21 Imagine this Simple Scenario Punching Tubing for Well Recompletion

22 Real Time Data – Gulf Of Mexico, 6 ft of Strip Guns Punching Tubing Head Tension PressureTempCCLShock 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

23 Head Tension PressureTempCCLShock 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 Real Time Data – Gulf Of Mexico, 6 ft of Strip Guns Punching Tubing

24 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

25 Field Data Shock detection when gun fired g ~80 lbs. drop in head tension ~10 lbs. drop in SURFACE tension 20 psi increase in BHP 2 deg C increase in BHT
