  1. Selective Perforation: A Game Changer in Perforating Technology- Case Study Amit Govil Perforation and Production Domain Champion Norway 2012 European and West African Perforating Symposium

  2. Layout • Background • Selective Perforation: Past / Present • Selective Perforation: Future • Selective Gun: Future • Gun–Assembly, Application • Case Study

  3. Background • Perforation engineering is a key element in successful well stimulation / production / injection • Selective perforation gun is required when multiple zones have to be perforated in a single run.

  4. Selective Perforation • Significant hardware • Reliable equipment • Engineer competency • Minimize failure modes • Maintain high safety standard

  5. Selective Technology: Past

  6. Selective Technology: Present 1.75” 0.75”

  7. Downhole Switch Communication

  8. Selective Technology: Risk • Manual handling • Mistakes while crimping connections • Possibility of pinch wire • Adaptors • Time-consuming operation • Typically every gun ~ 5 connection • Assume 1 min per connection • Considering 17 guns per run • Time required for making connections • 17*5 ~ 85 mins

  9. Selective Technology: Future • SafeJet- A gun system that is transported in the fully assembled form from the gun shop to the well location and is ready to run in hole. • Fully addressable and RF safe (up to 40 guns/run) • 3 1/8″ diameter • 16″ makeup length

  10. SafeJet: Reliability & Efficiency Pin connect SafeJet board, Nona pellet Detcord Wire channel Loading tube Shaped charge Pre-assembled with wiring and detonator cord - no booster, no crimping Disposable bulkheads SafeJet board (ASFS* + Secure* Technology)

  11. SafeJet: Rig up

  12. Case Study

  13. SafeJet: Value
