7" Retrievable Circulating Valve RTTS type for Fracturing Operation
Fracturing Operation 7" Retrievable Circulating Valve
Introduction of the 7" Retrievable Circulating Valve
The 7" Retrievable Circulating Valve can be locked closed when the
packer is unset to reverse fluid around the bottom of the packer. The 7"
Retrievable Circulating Valve is full opening allows tubing-type guns and
other wire line equipment to pass.
7" Retrievable Circulating Valve can be run directly above the packer
body or further up the work string. When placed in the hole, the valve must be in the locked-open position. The J-slot in the packer-body drag
block(or drag sleeve)must also be placed in the unset position.
