Patent number: 11959346Abstract: A method for offshore dual-drive core drilling with three layers of casings under surge compensation is provided. According to the method, a drilling vessel is located at set latitude and longitude coordinates by a dynamic positioning system; drill pipes are stabilized by a seabed template; torques and drilling pressures can be transmitted during drilling of the casings by means of surge compensation of the casings at a wellhead; during drilling for sampling, the surge compensation can compensate to a certain extent for a change in water depth caused by rising or falling tides, or surge, thereby preventing the casings from colliding with equipment and ensuring the safety of wellhead operation; and the drilling of three layers of casings is achieved by means of dual driver heads to effectively protect a wellbore wall, such that high core-drilling rate and good core-drilling quality are achieved during drilling for sampling.Type: GrantFiled: September 17, 2021Date of Patent: April 16, 2024Assignee: GUANGZHOU MARINE GEOLOGICAL SURVEYInventors: Lieyu Tian, Wu Guo, Nan Yang, Zhanzhao Li

Patent number: 11905784Abstract: Disclosed is a wellhead that includes a casing head, a tubing hanger and a rotation assembly connected to the tubing hanger. The tubing hanger is rotatable relative to the casing head and this rotation is effected by the rotation assembly. Also disclosed is a centraliser for use with tubing in a well. The centraliser has a first sleeve, a second sleeve, and a body that has a first band and a second band connected by a number of resiliently deformable members. The bands extend about the sleeves, with the bands being able to move relative to the respective sleeves. This can permit the centraliser to be fitted to tubing without requiring tight tolerances of tubing size, for example, and may reduce the friction between the body and the tubing to allow the tubing to be rotated within the casing during use.Type: GrantFiled: March 5, 2021Date of Patent: February 20, 2024Assignee: AS Innovative Holdings Pty LtdInventor: Kieran Chiverton

Hydraulic valve with linear adjustable throttling gate and a hydraulic velocity fuse throttling gate
Patent number: 11891928Abstract: A hydraulic valve having a body defining an inlet and an outlet. A motor is supported by the body and operates a shaft extending through an interior of the body, the shaft terminating in a gate. A spring is supported within the housing and influences the gate in an open position to permit fluid flow between the inlet and outlet. Upon the occurrence of a pressure differential resulting from a fluid flow through the inlet exceeding a biasing force of the spring, the gate is caused to displace against a valve seat communicating the inlet with the outlet in order to interrupt fluid flow in a standby mode and to define a closed position. The motor operates in a further throttling mode to linearly and incrementally displace the gate between the open and closed positions said outlet and in order to adjust flow through the outlet.Type: GrantFiled: June 15, 2020Date of Patent: February 6, 2024Assignee: The Oilgear CompanyInventor: Christopher Jon Walter -

Patent number: 11851984Abstract: An isolation valve system, method, and apparatus are provided that can isolate a wellbore and prevent fluids from exiting the well and prevent seawater from entering the well. The system can be a two-part design in some embodiments where a shear sub is selectively interconnected to a body via shearing screws. A sufficient force on the shear sub destroys the shearing screws and the shear sub is removed from the body. This movement rotates an actuator on the body, which in turn rotates a valve in the body to provide the isolating function during routine operation of a wellbore or during an emergency.Type: GrantFiled: October 17, 2022Date of Patent: December 26, 2023Assignee: Spoked Solutions LLCInventor: Bryce Elliott Randle
