  • Gas hydrate well control
    Patent number: 11913302
    Abstract: Methods and system involving well control. In some embodiments, the system includes an injection spool coupled to a subsea wellhead including an inlet, a manifold in fluid communication with the inlet of the injection spool for mixing one or more components of a well control treatment composition, a first container for storing natural gas in fluid communication with the manifold, and a second container for storing nitrogen in fluid communication with the manifold.
    Type: Grant

  • Rare earth alloys as borehole markers
    Patent number: 10539006
    Abstract: A magnetic marking method includes drilling a borehole and marking a position along an uncased section of the borehole with a magnetic marker comprising a magnetic rare earth alloy. A magnetic marker for open hole use includes an unconsolidated mass of high remanence, magnetized material that comprises a magnetic rare earth alloy. The magnetic marker for open hole use also includes a suspension fluid suited for conveying the magnetized material through a drill string bore into an open borehole. A magnetic marker for a casing terminus includes a magnet comprising a magnetic rare earth alloy and an attachment mechanism that secures the magnet to a casing shoe. Such magnetic markers for open hole use or a casing terminus can be used for borehole intersection operations.
