摘要： An improved wellhead structure having a housing with an internal landing seat to receive the landing shoulder on a hanger having a bore with a counterbore below the bore and a shoulder between, a hanger mandrel positioned within the counterbore and having an external flange having a diameter less than the diameter of the counterbore, a first bushing positioned above the mandrel flange and in engagement with said shoulder within the hanger counterbore, a second bushing positioned within the counterbore below said mandrel flange, and a support sleeve positioned within said hanger in supporting relationship to said second bushing, said bushings being of an electrical insulating material and sized to retain said mandrel in spaced relationship with respect to said hanger to prevent electrical connection therebetween. This structure also is used for supporting and sealing a tubing string or a section of a tubing string in a well while electrically insulating the section from the remainder of the string.

摘要： A vehicle seat for coupling to the floor of a vehicle comprising a seat back, a seat cushion, a first bracket, and a second bracket. The seat back is pivotable between at least a first position and a design position. The seat cushion is configured to be coupled to the vehicle floor. The first bracket is configured to be coupled to the vehicle floor and includes one of a keyed passage and a keyed pin configured to be received within the keyed passage. The second bracket is coupled to the seat back and includes the other one of the keyed passage and the keyed pin configured to be received within the keyed passage. The keyed passage is configured to receive the keyed pin only when the seat back is in a position the seat back will be prevented from assuming after the vehicle seat has been installed in the vehicle.

摘要： A completion system for a subsea well includes a tree having a generally cylindrical wall forming an internal bore therethrough and a production port extending laterally through the wall in communication with the internal bore. The internal wall has a landing arranged to support a tubing hanger having seals for sealing the production port between the tubing hanger and the internal wall, the production port being arranged to communicate with a lateral production fluid outlet port in the tubing hanger. A workover port extends laterally from an opening in the internal wall below the production port and the production port seals and a tubing annulus seal sealing the workover port from the tubing annulus. A tubing annulus port extends from an opening in the tree below the tubing annulus seal and the tubing annulus port and workover port being arranged to be in fluid communication externally of the internal bore.

摘要： A tubular connection, an example of which is a subsea wellhead having a primary and secondary seal areas allows the use of a backup or contingency gasket for engagement with the secondary seal area in the wellhead should a failure occur in the primary seal area. In the preferred embodiment, the primary and secondary seal areas are sufficiently separated such that the erosion damage which occurs from leakage with the original gasket adjacent the primary seal area, which can spread below the primary seal area, leaves the secondary seal area unaffected. A backup or contingency gasket can be inserted for sealable contact with the secondary sealing area for further well operations.
