`PGR2021-00097 – U.S. Patent No. 10,844,697
`
`
`
`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.

`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
