  • Patent number: 9822613
    Abstract: The system for inserting a tubular member from a surface into a subsea well includes a riserless vessel, a surface injector being mounted on the vessel at the surface and delivering tubular member, such as coiled tubing, to the subsea well from the surface, a subsea snubbing jack releasably engaged to the tubular member, a subsea hydraulic power unit connected to the snubbing jack, and a device to maintain tension of the tubular member between the surface injector and the snubbing jack. The dynamic control of the subsea snubbing jack provides either active additional force for pipe light and pipe heavy conditions or passive support of the tubular member for equilibrium conditions without a riser. The method is responsive to transitions between well conditions. A riserless system without a subsea injector can more efficiently and reliably insert coiled tubing under various well conditions and during changes in the well conditions.

  • Patent number: 9816323
    Abstract: A subsea drilling method and system controls drilling fluid pressure in the borehole of a subsea well, and separates gas from the drilling fluid. Drilling fluid is pumped into the borehole through a drill string and returned through an annulus between the drill string and the well bore and between the drill string and a riser. Drilling fluid pressure is controlled by draining fluid out of the riser or a BOP at a level between the seabed and the surface in order to adjust the hydrostatic head of drilling fluid in the riser. The drained drilling fluid and gas is separated in a subsea separator, where the gas is vented to the surface through a vent line, and the fluid is pumped to the surface via a subsea pump. A closing device and a choke line and valve can release pressure after a gas kick in the well.

    Abstract: An apparatus and method for providing a controllable supply of fluid, and optionally power and/or communication signals, to a subsea equipment are provided. The fluid may be a water-based fluid, oil-based fluid, or chemicals. The apparatus includes a reservoir disposed on a seabed for storing a supply of fluid for delivery to the subsea well equipment. A subsea pumping device is configured to receive the fluid from the reservoir, pressurize the fluid, and deliver the pressurized fluid to an accumulator of a hydraulic power unit disposed on the seabed. The hydraulic power unit can store the pressurized fluid and control an output of the pressurized fluid to the subsea well equipment, thereby providing a subsea fluid source for the subsea equipment.

  • Patent number: 8893801
    Abstract: A method is presented for connecting and disconnecting sections of a work string for use in a subterranean wellbore. A preferred method of disconnecting includes the steps of positioning a stinger and a downhole tool assembly of a work string adjacent upper and lower sealing rams, such as in a BOP and lubricator assembly. The sealing rams are closed, defining a first and second pressure zone adjacent the tool. A differential pressure is applied across the pressure zones, moving a piston element in the tool assembly. Axial movement of the piston element causes relative rotational movement of cooperating locking elements. In one embodiment, the locking elements are rotated to an unlocked position and then move relative to one another axially in response to a biasing spring. The relative axial movement of the locking elements results in unlatching of a latching assembly, thereby disconnecting the tool and stinger.

  • Patent number: 8887812
    Abstract: A containment system having a containment dome and a seal plate which is attached to an oil wellhead casing or riser to prevent oil spills and contamination when an oil leak occurs. The containment dome is sealed to the seal plate by a compression mechanism so that oil will not leak from the containment dome. The containment dome can provide a wellhead patch to a wellhead system wherein the wellhead patch can interface with a capping stack. Chemicals can be injected into the containment dome to prevent hydrates from forming. All aspects of controlling and operating an oil wellhead can be performed through the containment dome and seal plate, and all aspects of installation, regulation, and control of the containment dome can be performed by remote operating vehicles under water.

  • Patent number: 8881829
    Abstract: A backup blowout system for a subsea wellhead positioned between an existing blowout prevention system and the wellhead. The backup blowout system includes an independently operated shear/blind ram assembly that attaches to a standard wellhead connector that connects to the wellhead. The ram assembly includes an upper neck with an upper flange on which a dual housing assembly is attached. The dual housing assembly includes a primary housing longitudinally aligned over a secondary housing. The primary and secondary housings include lower bodies and upper necks that have identical diameters. During assembly, the existing primary blowout prevention system is initially connected to the primary housing and the ram assembly is connected to the wellhead connector. When a blowout occurs, the primary housing is disconnected from the secondary housing to expose the upper neck of the secondary housing upon which a replacement primary blowout prevention system or cap may be attached.

  • Patent number: 8875791
    Abstract: A fiber optic coiled tubing assembly of multiple segments and coupling mechanism therefor. The assembly may be assembled from multiple coiled tubing segments which are pre-loaded with fiber optic line. Thus, the coupling mechanism may be employed for physical coupling of the coiled tubing segments as well as communicative coupling of the lines of the separate segments to one another. As such, pumping of a single fiber optic line through the coiled tubing assembly following coupling of the segments may be avoided. This may be of particular benefit for offshore operations where the joining of multiple coiled tubing segments is likely due to crane load capacity limitations and where such pumping may consume vast amounts of time.
