  • Patent number: 8978774
    Abstract: A subsea mud pump can be used to return heavy drilling fluid to the surface. In order to provide a less stringent requirement for such a pump and to better manage the bottom hole pressure in the case of a gas kick or well control event, the gas should be separated from the drilling fluid before the drilling fluid enters the subsea mud pump and the pressure within the separating chamber. The mud pump suction should be controlled and kept equal or lower than the ambient seawater pressure. This can be achieved within the cavities of the subsea BOP by a system arrangement and methods explained. This function can be used with or without a drilling riser connecting the subsea BOP to a drilling unit above the body of water.

  • Patent number: 8967270
    Abstract: A rigless abandonment system including a surface vessel having an attached lifting device and a moonpool. The system further includes a cutting module configured to connect to a subsea wellhead, the cutting module having a wellhead connector having an actuatable lock and release mechanism, a motor assembly, and a cutter. An umbilical line connects the cutting module to the surface vessel, wherein the lifting device is used to raise and lower the cutting module connected to the surface vessel through the moonpool. A method for performing rigless casing cutting and wellhead removal operations, the method includes positioning a surface vessel above a subsea wellhead, where the surface vessel has a moonpool and a lifting device. The method further includes providing a cutting module, and deploying the cutting module through the moonpool, wherein the cutting module is connected to the surface vessel by an umbilical line.

  • Patent number: 8967272
    Abstract: A modified casing coupling houses a pressure relief valve body having a through bore with opposing end openings. The through bore communicates with the interior of the modified casing coupling at one end opening thereof and with an area surrounding the modified casing coupling at an opposite end opening. The through bore includes a ball seat adjacent one end opening thereof which receives a sealing ball. The ball is urged in the direction of the ball seat by a tensioning element. The ball is exposed to annular pressure trapped between successive lengths of well casing located in the well borehole. The amount of tension exerted on the ball by the tensioning element is selected to allow the ball to move off the ball seat to release trapped annular pressure between the selected casing strings once a certain annulus pressure is reached.

  • Patent number: 8960306
    Abstract: An annular blowout preventer assembly has an annular element housing and a central cavity with an elastomeric annular element in the central cavity. An annular element piston is located within the central cavity in engagement with the annular element. A connector housing has an upper end that abuts a lower end of the annular element housing. Bolts extend upward from the connector housing into threaded blind holes in the annular element housing for securing the connector housing to the annular element housing. A locking element is carried within the connector housing for radial inward movement into engagement with a profile on a mandrel of a blowout preventer stack.

  • Publication number: 20150027719
    Abstract: Systems and methods for quick access and control of a blown-out well or well that is flowing uncontrollably into the environment. Preferred embodiments of the present invention provide a re-entry of the casing of the blown-out well below the mud line and the inoperable blowout preventer. The present invention also provides a method to re-enter a production, or injection well, either subsea below the mud line or above the mud line for surface facility applications. According to a preferred embodiment of the present invention, a miniature wellbore is created from the outer casing through the various smaller casing strings into the final wellbore to protect the structural integrity of the well. Once the casing is safely penetrated, coil tubing and or kill weight fluid can be introduced to stop the uncontrolled flow of reservoir fluid. The well can then be sealed with cement and abandoned as normal practice dictates.

  • Publication number: 20150027717
    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.

  • Publication number: 20150021037
    Abstract: Systems and methods contain fluids discharged from a subsea well or at the surface by capping the well blowout with a pre-positioned capping device and diverting flow of hydrocarbons to a secondary location for disposal/handling in situations where casing integrity is compromised preventing ability to close in the flow of the hydrocarbons. The capping device includes at least one blind shear ram and is separate from a blowout preventer. Different personnel offsite of a rig drilling the well may have access and control to operate the device.

The capping device includes at least one blind shear ram and is separate from a blowout preventer. The blowout preventer may operate to control well events up to a certain pressure, above which the capping device is employed since the capping device has a higher pressure rating than the blowout preventer.
