  • Riser surge protection system
    Patent number: 11391140
    Abstract: A system for surge protection of a riser adapted to transport gas from a hydrocarbon production well or for surge protection in a well, the system comprising: a flexible tubing, wherein a portion of the flexible tubing extends into the riser or into the well and wherein the tubing terminates inside the riser or inside the well; a pressure control system arranged to create a pressure differential within the flexible tubing such that liquid is drawn from the riser or the well into the flexible tubing if liquid is present in the riser or the well; wherein the length of said portion of the flexible tubing is variable depending on the amount of liquid drawn into the flexible tubing.
    Type: Grant
    Filed: October 12, 2018
    Date of Patent: July 19, 2022
    Assignee: EQUINOR ENERGY AS

  • Prevention of surge wave instabilities in three phase gas condensate flowlines
    Patent number: 10556210
    Abstract: There is provided a process for the prevention or reduction of surge wave instabilities during the transport in a flowline of a three phase gas condensate comprising a gas phase, an aqueous phase and a condensate phase, characterized in that a dispersing agent is added to the three phase gas condensate which is able to disperse the aqueous phase in the condensate phase or the condensate phase in the aqueous phase, and a means for the prevention or reduction of surge wave instabilities during the transportation of a three phase gas condensate.
