Casing Grout Valves
Casing Grout Valves provide a simple means of effectively and safely grouting the casing. Similar to the One-Shot Casing Grout Packers, the Grout Valve is run inline with the casing upon installation.
When the casing is installed to total depth, the
grout stinger attached to the drill string is run inside the 
casing
until it lands out on the valve. Grout can then be pumped to surface
through the valve before the stinger is removed from the casing. There
is no need for drill out - once the stinger is removed, the well is
complete.
