    Abstract: An offshore well system for a subsea well, including a floating platform, a drilling riser system connected with the well for drilling operations, and a production riser system connected with the well for production operations. The drilling system also includes a riser tension system. The riser tension system is capable of compensating for movement of the platform while adequately tensioning both drilling riser system and the production riser system when each are connected to the well.

    Abstract: A system for coupling to equipment at a well includes a connector and/or an outer sleeve sub engageable with the connector, each including an internal bore. An isolation sleeve includes a seal and is positioned at least partially within the internal bore, in which the seal is axially movable with respect to the internal bore so as to be positionable to seal against the equipment.

    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: An offshore well drilling system for drilling a subsea well, including a floating platform, an external riser extending from the subsea well, and an internal riser extending from the subsea well to the platform. The internal riser is nested within the external riser. The system also includes an external riser tension device to apply tension to the external riser. The system also includes an internal riser tension device, separate from the external riser tension device, to apply tension to the internal riser.
