Submerged Well Patents (Class 166/335)
  • Patent number: 10597974
    Abstract: A valve assembly for use in a wellbore of an oil, gas or water well, having a valve seat to seat a valve closure member such as a ball, and a control member that is adapted to cycle the valve assembly between first and second configurations of the valve assembly when the ball is seated on the seat. The valve assembly may be adapted to return the valve assembly to the first configuration when the valve closure member is seated on the seat, and may repeatedly, continuously and/or sequentially cycle from first to second configurations and back to first configuration to open and close an outlet port while the same valve member is seated on the seat. The valve seat may comprise first and second seat members and retain the ball in a cleft between the first and second seat members.

  • Patent number: 10577910
    Abstract: In accordance with presently disclosed embodiments, a system and method for using fuel cells to generate electricity for powering well stimulation equipment (e.g., high pressure hydraulic pumping units) at a well stimulation site are provided. The fuel cells may be coupled to the stimulation equipment via a DC/AC converter and, in some embodiments, via a variable frequency drive (VFD). The fuel cells may be arranged in a fuel cell stack that is used to generate electricity to power various electrical devices (e.g., electric motors) on the equipment. The fuel cells generally operate at higher efficiencies than is available through the use of diesel engines. In addition, the fuel cells may require less frequent refueling and provide a more centrally located area for refueling, lower emissions, and quieter operations than are currently available using diesel engines.

  • Patent number: 10472900
    Abstract: A bend stiffener (50) includes an elongate stiffener body (52) having polymer material and two ends. A passage (58) extends through the stiffener body from end to end for receiving and embracing a flexible member (60). The stiffener body includes a coupling (66) for mounting the stiffener body in cantilever fashion. The stiffener body is sufficiently flexible to curve somewhat along with the flexible member under a bending load but is sufficiently stiff to resist excessive curvature which could damage the flexible member, and sufficiently resilient to recover its original shape afterwards. The stiffener body includes at least two stiffener body parts (64a, 64b) defining the passage. Each stiffener body part includes a respective interface member (68, 70) having material stiffer than the polymer material of the stiffener body. A securing arrangement (80, 83) secures the interface members of different stiffener body parts together around the elongate flexible member.

    Abstract: The invention in one of its aspects provides a connection apparatus for a subsea hydraulic circuit and method of use in a sampling application. The apparatus comprises a longitudinal body configured to be removably docked with a subsea hydraulic circuit receptacle. The body comprises a plurality of radial ports axially displaced along the body, and an axial bore accommodating a spool having at least one fluid barrier. The spool and fluid barrier are actuable to be axially moved in the bore to control axial flow paths along the bore between the plurality of radial ports. The apparatus may be configured as a sampling hot stab in an application to sampling a production fluid from a subsea hydrocarbon production system.

    Abstract: Systems and methods for accessing and/or harvesting hydrocarbons from a wellbore. A method may include modeling a well to determine a length of a stimulation zone in the production interval, wherein the model is based, at least in part, on a reaction time for a stimulation process. Packers are placed in the well to fluidically isolate the stimulation zone from other zones in the well. The targeted zone is stimulated, such as by acid treatment. Hydrocarbons may be recovered from the stimulation zone.

    Abstract: An apparatus, system and process for deployment of subsea drilling equipment through a moon pool of a drilling vessel is disclosed. The drilling equipment may include a subsea mudlift pump (MLP) that is configured to be deployed below the surface of the ocean and is adapted for conducting dual gradient drilling (DGD) operations. In the apparatus and process, the MLP may be suspended temporarily aboard the vessel by a holding mechanism. The MLP may be combined first with a lower marine riser package (LMRP) prior to suspension of the MLP and/or MLP/LMRP aboard the drilling vessel. An equipment combination, comprising at least a MLP and a LMRP, may be with a BOP, the mating occurring at a position below the surface of the ocean. In one aspect, the BOP may be separately deployed into the ocean, and then subsequently mated subsea with the LMRP and/or a MLP/LMRP combined equipment package.

  • Patent number: 8939212
    Abstract: A subsea cap method and system having a canister attached to a port in a subsea cap that is positioned on a subsea structure and materials contained within the canister for release through the port into the defined area beneath the subsea cap and around the open upper end of the subsea structure. That is, the materials treat the water inside the cap and may optionally also treat the water outside the cap. The canister can be attached to, or removed from, the subsea cap subsea without removing the subsea cap from its resting place on the subsea structure. The system can be deployed via an ROV, diver or other means. The positioning of the subsea cap on the subsea structure and the placement and active or passive release of the material through the port into the defined area provides a system that protects the subsea structure from such problems as falling debris, silt, corrosion and organic growth while saving valuable time and resources.
