Dual pack-off assembly for subterranean well with wireline and capillary tube
A recently granted patent (Publication Number: US11965392B2) discloses a system designed for use in subterranean wells. The system includes a bottom hole assembly, a wireline, a capillary tube, and a dual pack-off assembly. The dual pack-off assembly consists of blowout preventers and pack-offs that seal around both the wireline and the capillary tube while they are deployed in the well. The system also features a packer that can be set in the well in response to pressure applied to the capillary tube, as well as a pressure actuated disconnect tool that can be released in response to a different pressure level applied to the capillary tube.
Moreover, the patent describes a method for deploying the bottom hole assembly into a wellbore, setting the packer by increasing pressure in the capillary tube, and disconnecting the pressure actuated disconnect tool by further increasing the pressure. The method involves inflating the packer and transmitting pressure to the packer via the pressure actuated disconnect tool. Additionally, the method includes the use of a dual pack-off assembly with blowout preventers and pack-offs, as well as a lubricator connected between the assembly and the wellhead. This innovative system and method aim to enhance the efficiency and safety of operations in subterranean wells by providing a reliable sealing mechanism and controlled deployment process.
