Plug Launcher

A quality cement job is vital to ensuring uninterrupted zonal isolation and long term well integrity. The Volant Paddle Valve Plug Launcher enables the worry-free release of plugs through a remote pneumatic release system. The Plug Launcher directs cement into the annular space between the main body and cage, where plugs are housed. When plugs are ready to be launched, the paddles are pneumatically opened, redirecting cement to the top of the plug, forcing the plug out for a positive launch. With an integrated interlock, plugs are released in the correct sequence. Designed without protruding parts, the Plug Launcher improves safety on the rig floor during rotation and reciprocation.

1The PVPL2-5.5 tool is available in two configurations. One can launch two plugs up to 10.25 in. (260.0 mm) each and is 75.2 in. (1,915 mm) in length. The other can launch two plugs up to 29.38 in. (746.0 mm) each and is 115.2 in. (2,930 mm) in length.
2The PVPL2-9.63 tool can be built to accommodate longer plug lengths if necessary. Contact Volant Sales for more information.
3The PVPL2-9.63 tool launches up to two 11.75 in. (298.0 mm) plugs. It can also launch a single plug up to 29.50 in. (749.5 mm), which required modifying the control panel’s interlock features. Contact Volant Customer Support for details.
4The PVPL2-9.63 tool can be configured to launch 7.0 or 9.63 in. plugs. To launch 7.0 in. plugs, additional components are required to narrow the tool’s inner bore.
