A setting tool disposed on tubing runs a packer into casing. During a setting process, a plug is engaged on a seat of an intensifying piston disposed in the tool. Tubing pressure applied against the seated plug moves the intensifying piston, which produces intensified pressure on fluid in a first volume of the intensifying piston communicated to a second volume of a setting piston. In response, the setting piston moves on the tool toward the packer's packing assembly. At some point in the process, the seated plug can be released from the seat. Additionally in the process, the second volume can fill with actuation fluid drawn through a fill valve from an annular space between the setting tool and the casing. The intensifying piston can then be reset as the actuation fluid is communicated from the second volume to the first volume.

Intensifying setting tool for packer

A subsea wellhead system includes: a hanger including a first fiber optic cable; a tree including a second fiber optic cable; a seal sub configured to be coupled to the tree and engaged with the hanger, the seal sub including a fiber optic communications line configured to be communicatively coupled to the first and second fiber optic cables; a transducer configured to be disposed at a downhole location and configured to be communicatively coupled to the first fiber optic cable; a first photodetector disposed in the hanger and configured to convert a light signal traveling through the first fiber optic cable from downhole to an electrical signal communicated to the electrical connection; and a first optical transmitter disposed in the seal sub and configured to convert the electrical signal traveling through the electrical connection into a light signal communicated to the second fiber optic cable.

Downhole fiber optic transmission for real-time well monitoring and downhole equipment actuation

Systems and methods for real-time monitoring of well conditions and actuation of downhole equipment are provided. A subsea wellhead system comprises a tubing hanger landed in a wellhead, wherein the tubing hanger comprises a first fiber optic cable; a tree landed on the tubing hanger, wherein the tree comprises a second fiber optic cable; a transducer disposed at a downhole location, wherein the first fiber optic cable is communicatively coupled to the transducer and extends between the transducer and the seal sub; and a seal sub, wherein the seal sub is landed in the tubing hanger, wherein the seal sub comprises: a fiber optic communications line that is communicatively coupled to the first fiber optic cable and the second fiber optic cable; wherein the seal sub and the tubing hanger form an electrical connection regardless of an orientation of the tubing hanger relative to the tree.
