Full Bore Retrievable Circulating Valve / RTTS Circulating Valve
The Full Bore Retrievable Circulating Valve is similar to RTTS Circulating valve in Halliburton. The full bore retrievabel circulating valve is a locked-open/locked-closed valve that serves as both a circulating valve and bypass in drill stem testing service. 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 full bore retrievabel circulating valve is run in or pulled out of the hole, a packer bypass is generally used.
The full bore retrievable circulating valve can be locked closed when the packer is unset to reverse fluid around the bottom of the packer. The circulating valve is designed with full opening allows tubing-type guns and other wire line equipment to pass
