Study Notes
Perforation Control Devices
- Control the flow of fluids during perforation to isolate the zone being perforated
- Installed above and below the perforating interval
- Examples: packers, bridge plugs, or sliding sleeves
Surface Equipment
- Supports perforation operations at the wellhead
- Includes: pressure control systems, surface control panels, data acquisition units, and monitoring devices
- Pressure control systems control wellbore pressure during perforation
- Surface control panels allow for remote operation and monitoring of perforating guns
- Data acquisition units and monitoring devices capture key parameters during perforation
Safety Equipment
- Essential for protecting personnel and equipment during perforation operations
- Includes: personal protective equipment (PPE), fire extinguishers, blowout preventers, and safety barriers
Equipment Used in Well Perforation
Perforating Guns
- Primary tools used to create perforations in the well casing and reservoir rock
- Consist of a cylindrical carrier housing shaped charges
- Explosive devices designed to create tunnels or perforations in the casing and penetrate into the reservoir rock
- Come in various sizes, configurations, and phasing options to suit specific well conditions
Conveyance Systems
- Used to deliver the perforating guns to the desired depth in the wellbore
- Choice of conveyance depends on well characteristics
- Common conveyance methods: wireline, tubing-conveyed perforating (TCP), or coiled tubing
- Wireline often used for vertical or deviated wells
- TCP and coiled tubing suitable for horizontal or highly deviated wells
Perforation Accessories
- Used in conjunction with perforating guns to enhance performance and ensure safe and efficient operations
- Examples: centralizers, shock subs, detonating cord protectors, and firing heads
- Centralizers position the perforating guns concentrically within the wellbore
- Shock subs reduce the impact of vibrations during perforation
- Detonating cord protectors and firing heads provide safety features for handling and initiating the shaped charges
