Full Bore Retrievable Circulating Valve 7" x 10000psi
Drill stem testing RTTS Circulating valve for DST operation
Introduction of the RTTS Circulating valve
The RTTS circulating valve is a locked-open/locked-closed valve that serves as both a circulating valve and bypass. The clearance between the RTTS packer (or any hookwall packer) and the casing ID is relatively small. To reduce the effect of fluid-swabbing action when the tool is run in or pulled out of the hole, a packer bypass is generally used.
Features and Benefits
• The valve can be locked closed when the packer is unset to reverse fluid around the bottom of the packer.
• The tool's full opening allows tubing-type guns and other wireline equipment to pass.
