    Abstract: An offshore well system for a subsea well. The system includes a floating platform, an external riser and an internal riser nested within the external riser. A external riser tension device tensions the external riser. The drilling system also includes a surface wellhead system that includes a wellhead, a collet, and a flange assembly. The wellhead, collet, and flange assembly are assembled to establish a common bore for receiving the top of the internal riser. A gasket located between the top of the internal riser and an inner shoulder of the flange assembly seals between the wellhead system and the top of the internal riser. The surface wellhead system also retains the internal riser in tension with the wellhead, the internal riser extending above the wellhead into the collet.

    Abstract: A metal end cap seal for sealing against resent invention relates to seals within a fluid system. The metal end caps of the seal include protrusions or nibs on the terminal ends of the caps, providing for reduced friction during installation and use. The seal may also include a base elastomer and an insert elastomer, the base elastomer and insert elastomer having different material properties from one another. The insert elastomer is selected to reduce friction with a sealing surface.

    Abstract: The riser system of the present invention includes an external production riser for floating structures with interfaces to the dry and subsea wellheads, internal tieback riser with a special lower overshot/slipping connector for elevated temperatures. The seals can be metallic and/or non-metallic dynamic seals. Special centralizing pipe connectors and a special subsea wellhead tubing hanger are also included. This riser system avoids the penalty of pipe within pipe differential thermal growth and the resulting unwanted effects on the floating structure. This is accomplished by allowing an overshot sealing slipping connector to swallow an expanding polished rod as thermal conditions cause pipe elongation axially. When elevated temperatures fall to ambient the opposite occurs as the pipe shrinks axially. Alternatively, a system is possible where a two pipe drilling riser is needed. The internal pipe in this case would be an inner riser rather than a tubing string.

    Abstract translation: 本发明的立管系统包括用于浮动结构的外部生产提升器，其具有与干式和海底井口的接口，具有用于升高的温度的特殊的较低的过冲/滑动连接器的内部连接提升管。 密封件可以是金属和/或非金属动态密封件。 还包括特殊集中管连接器和特殊海底井口管挂架。 这种提升管系统避免了管道差热过程中的管道损坏以及对浮动结构造成的不必要的影响。 这是通过允许超轻的密封滑动连接器吞咽膨胀的抛光棒来实现的，因为热条件导致管轴向伸长。 当升高的温度降至环境温度时，管道会沿轴向收缩。 或者，可能需要两个管道钻井立管的系统。 在这种情况下，内管将是内立管而不是油管柱。
