Well Perforation Equipment

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
