    Abstract: A turbine assembly is provided for downhole components of a well system. The turbine assembly includes a translational component which translates when a fluid is passed through the turbine assembly. The turbine assembly also includes a braking system which includes one or more magnets in magnetic communication with a conductive component. The braking system enacts a braking force onto the translational component due to the relative translation of the one or more magnets with the conductive component. The braking force from the braking system is proportional to the rate of translation of the translational component.

    Abstract: A steam operated flow control device and method is disclosed. In one mode, the flow control device enables steam to be injected into a subterranean formation region containing hydrocarbons. In another mode, the flow control device enables the hydrocarbons to be produced from the subterranean formation to the surface. The flow control device includes a piston disposed between a housing and a mandrel having aligned ports, which slides between a first position where one set of ports align with the ports in the housing and the mandrel and a second position where another set of smaller ports align with the ports in the housing and mandrel. The piston is operated by a bellows having a chamber which contains a fluid. The fluid responds to temperature and/or pressure variations.

    Abstract: A metal patch for patching a downhole well casing comprises a metal sealant having a shape congruent with a section of the downhole well casing and transition-able from a first state to a second state. The metal sealant expands and hardens in response to hydrolysis. The metal sealant is one of an alkaline earth metal, a transition metal, and a metal oxide. The metal sealant can be one of an alkaline earth metal, a transition metal, and a metal oxide and at least one alloy, wherein the at least one alloy is selected from a group consisting of Al, Zn, Mn, Zr, Y, Nd, Gd, Ag, Ca, Sn, and RE. The at least one alloy can be alloyed with a dopant that promotes corrosion, such as Ni, Fe, Cu, Co, Ir, Au, and Pd. The at least one alloy can be alloyed with a dopant that inhibits passivation.

    Abstract: The disclosed embodiments include gravel pack assemblies, method to bypass a fluid restrictor during gravel packing operations, and methods to control fluid flow during and after gravel packing operations. In one embodiment, a gravel pack assembly including a flow restrictor that is coupled to a downhole string that is deployed in a borehole is disclosed. The flow restrictor forms a first fluid passageway from the borehole to an internal cavity of the string. The gravel pack assembly includes a fluid bypass portion having a first chamber, a sealing member inserted into the first chamber; and an actuation assembly operable to actuate the sealing member. The fluid bypass portion forms a second fluid passageway from the borehole to the internal cavity of the downhole string prior to actuation of the actuation assembly. After actuation of the actuation assembly, fluid flow through the second fluid passageway is restricted by the sealing member.
