Introudction of Retrievable Casing Packer
The Retrievable Casing Packer is a sort of hook-wall full bore packer. The packer is designed with J slot and mechanical setting. The full opening design of the RTTS Packer allows unrestricted fluid flow and tool movement through the tubing bore. The RTTS circulating valve as the bypass valve is held closed by pressure from below and in turn helps prevent upward movement of tubing. A pressure balanced bypass valve which is held open when running and retrieving, prevents swabbing effect. The valve also allows debris to be washed from the top of the packer when releasing.
