摘要： A device for cutting and plugging underwater pipes, the device includes a frame with one or more clamps for securing the device to the pipe. Attached to the frame is an arm having a first end and a second end. The first end is attached to an actuation element that in combination with a support bar can pivot and extend the arm. A motor is attached to the second end of the arm. A saw blade and pipe plug is concentrically mounted to the motor. The motor powers the saw blade to cut the pipe transversely. The arm then positions the pipe plug concentric with the cut pipe, and in combination with rotation of the motor, plugs the cut pipe with the pipe plug.

摘要： The emergency valve assembly (5) for extraction wells according to the invention comprises A) an external housing (50) and B) a rotating stopper (54). The pass-through duct (52) is arranged for the passage of a production and/or drilling line arranged for containing and carrying, through at least one relative pipe (9), extraction fluids such as, for example, petroleum, oil, water, sludge, rock debris and/or earth, natural gas, or other fluids extracted from an underground reservoir. The valve (5) also comprises a stopper drive (56), arranged for actuating the rotating stopper (54) making it rotate so as to shear the production or perforation line passing through it, in particular shearing the pipe (9) and closing the pass-through duct (52). The pass-through duct (52, 520) has a minimum passage section having a diameter equal to or greater than seven inches. It provides an effective additional safety measure in the case of emergencies.

摘要： Wellbore tubulars including a plurality of selective stimulation ports and methods of utilizing the same are disclosed herein. The wellbore tubulars include a tubular body including an external surface and an internal surface that defines a tubular conduit. The wellbore tubulars also include a plurality of selective stimulation ports, and each selective stimulation port includes an SSP conduit and an isolation device that is configured to selectively transition from a closed state to an open state responsive to a shockwave having greater than a threshold shockwave intensity. The methods include methods of stimulating a subterranean formation utilizing the wellbore tubulars. The methods also include methods of re-stimulating the subterranean formation utilizing the wellbore tubulars.

摘要： An autonomous BOP system is provided for stopping an uncontrolled flow of formation hydrocarbons comprising two or more sensors distributed along a length of a subsea blowout preventer to monitor a drill pipe inside a blowout preventer and measure critical parameters. A subsea computer using predictive-software monitors a blowout preventer along with material critical parameters and calculates a blowout preventer configuration and sequence to arrest a well blowout. Blowout preventer components are fine-tuned and operational modes are added to aid an arrest of a well blowout under realistic conditions.

摘要： A gate valve assembly (100) for use in subsea workover systems is disclosed. In an embodiment, the gate valve assembly (100) includes a valve block (102). The valve block (102) includes a cutting gate (204) disposed in a valve cavity (206) such that the cutting gate (204) can engage in a reciprocating motion in the valve cavity (206) between an “open” position and a “closed” position. The reciprocating motion of the cutting gate (204) results in a cutting operation of a tubing conveyed string passing through the gate valve assembly (100). The gate valve assembly (100) further includes a slug pit (202) formed in the valve block (102) alongside the valve cavity (206). The slug pit (202) defines an opening which can contain one or more cuttings from tubing conveyed springs resulting from the cutting operation. The reciprocating motion of the cutting gate (204) transports one or more cuttings of the tubing conveyed string to the slug pit (202).

摘要： A shearing device that torsionally shears an oilfield tubular by gripping the tubular at vertically spaced apart locations and exerting a torsional force at the locations. Tong assemblies are provided for gripping the tubular, where the tong assemblies include a tong member pivotally mounted on a tong arm. The tong assemblies may be housed in a blowout preventer mounted on a wellhead assembly; projecting the tong assemblies radially inward engages the tong members with the tubular, and moving the arm further radially inward imparts the torsional force onto the tubular. In an alternate embodiment, the shearing device includes holding rams that project radially inward to engage the tubular and a torque rack that tangentially engages the tubular thereby torqueing the tubular.
