  • Patent number: 9051818
    Abstract: Configurations and methods for subsea hydrocarbon production at high pressure wells are contemplated in which production control is achieved by implementing two choke valves in series between the wellhead and the riser. The first production choke reduces pressure from well pressure to a reduced pressure, while the second production choke further reduces the pressure from the reduced pressure to riser pressure. The first production choke is preferably coupled to the production tree, and the second production choke is coupled to production tree, a subsea pipeline-end device (e.g., PLET or PLEM), a well jumper, or a flowline jumper.

  • Publication number: 20150122482
    Abstract: An annular blowout container (ABOC) that may be used in multiples in a stack in conjunction with additional gate and shear valves to protect a wellhead. The ABOC incorporates a cylindrical formed bladder that provides a tight constrictive seal around whatever pipe or tubing may be in the well bore. The bladder is made of top and bottom rotator plates with springs extending between the plates. The springs are encased in Teflon® and held in place by Kevlar® then covered over completely with cured Viton® that is injected to complete the overall bladder in a molded form. Rotation of the top and bottom rotator plates effects a twisting constriction around the drill pipe or tubing. Electrical and hydraulic operational components are housed inside chambers within the ABOC for predominantly self-contained operation. The cylindrical bladder assembly may be removed and replaced after extended use.

  • Patent number: 7278481
    Abstract: A method and system are provided for controlling the production of oil and gas in a well such that the well operates at the edge of gas coning. Thereto the flow rate and/or pressure of the produced well effluents are controlled by a dynamically controlled choke such that continously a limited amount of gas is entrained in the produced crude oil, whereas full gas coning and breakthrough of gas from the gas cap is prevented. The choke may be controlled by a control system which includes an algorithm that takes wellhead temperatures, pressures and choke position as measured variables and which maintains the average bulk velocity of the well effluents at a substantially constant and relatively high level. Optionally, the system also maintains an optimal gas-to-liquid ratio of the well effluents.
