2. IPS-15-11  Overview of typical CT gun string characteristics  Case history of perforating guns detonating in the lubricator or in vertical portion of horizontal wells during Coiled Tubing (CT) operations  Development of a device to meet customer safety requirements to prevent vertical detonations during CT operations  Overall testing from prototyping to customer use

3. IPS-15-11 Shear Pins Percussion Initiator Firing Pin Perforating Gun

4. IPS-15-11 Firing Head Perforating Gun 1 Perforating Gun 2 Transfer Sub Time Delay Fuse

5. IPS-15-11  Example of damaged lubricator due to perforating gun detonation  Multiple detonations have occurred in the lubricator

6. IPS-15-11  Average of 6 – 8 perforating guns inside lubricator per CT operation

7. IPS-15-11 VIDEO

8.  Multiple detonations have occurred in the vertical portion of the well during CT operations in U.S. horizontal shale plays  Unwanted perforating damage compromises vertical casing  No knowledge of guns detonating while tripping into the well IPS-15-11

9. Impact Input High Order Output IPS-15-11  System relies on the interrupters ability to disrupt the shockwave  Stops the shock transfer from the initiator to the perforating gun

10. IPS-15-11  While in vertical orientation the interrupter is in a “no-fire” position (Patent Pending*)

11. IPS-15-11  Once the system reaches the horizontal portion of the well the interrupter allows for successful initiation transfer (Patent Pending*)

12. TestingVertical Inverted Vertical HorizontalInclination 30°Inclination 60° InternalXXXXX IPS-15-11  Multiple Tests at various orientations and inclinations.  Released to the industry after 6 months of successful field testing.

13.  Demand for a safety device after multiple vertical detonations in the lubricator and in the vertical portion of horizontal well  Developed an inline interruption device for coiled tubing perforating operations in horizontal wells  Currently being utilized in U.S. Horizontal Shale Wells
