  • Wellhead Bracing System
    Publication number: 20240110463
    Abstract: A wellhead bracing system for a subsea well includes a base plate assembly and a wellhead brace assembly. The base plate assembly comprises a top surface, a bottom surface, a base plate aperture, and a plurality of anchor holes. The wellhead brace assembly comprises a vertical plate assembly having a cylindrical shape, a horizontal plate assembly to which the vertical plate assembly is attached, and a vertical support assembly attached to an outer surface of the vertical plate assembly and attached to the top surface of the horizontal plate assembly. Horizontal plate holes of the horizontal plate assembly are configured to attach to studs on the top surface of the base plate to secure the wellhead brace assembly to the base plate assembly. The wellhead bracing system slides onto a wellhead of the subsea well and braces an exterior of the wellhead.

  • Mitigation of frictional heat checking in well casing
    Patent number: 11060390
    Abstract: Downhole casing temperature may be predicated at the drill string/casing interface as a function of side force on the casing due to drill string tension, the speed or rate of penetration of the drill string in the axial direction, the rate of rotation of the drill string, and a calibrated/assumed friction factor. Predicted down hole casing temperature may be used as a proxy to monitor casing integrity.
