Abstract: A graphene heat exchanger for absorbing thermal energy and located in a downhole tool. The downhole tool is located in a borehole intersecting an earth formation and comprising a thermal component. The heat exchanger includes graphene and is thermally coupled to the thermal component. The heat exchanger is configured to absorb thermal energy from the thermal component or absorb ambient thermal energy from the earth formation.

Abstract: A system and method for controlling the direction of a burner flame exposed to potentially impinging wind or other air flows. At least one fluid nozzle is mounted in proximity to a burner nozzle. The fluid nozzle is configured to produce a spray of fluid provided by a fluid supply system. As the spray is produced, an area of low pressure is created near the fluid nozzle, creating a buffer air flow around the spray. The buffer air flow is directed towards the potentially impinging air flow such that at least a portion of the potentially impinging air flow is counteracted and no longer impinges upon the burner flame. One or more fluid nozzles may be used in the burner flame control system to counteract one or more air flows.

Abstract: Systems and related methods are disclosed that involve the use of a magnetic downhole assembly or a magnetic downhole tool. The assembly and tool include a mu-metal sleeve that is operable to isolate a magnetic field and a permanent magnet disposed within the mu-metal sleeve. The assembly and tool also include an actuator that is operable to selectively extend and retract the sleeve to alternatingly expose and shield the permanent magnet. A conveyance is operable to deploy the magnetic downhole assembly and tool to a selected location within a wellbore and a controller is communicatively coupled to the actuator and operable to generate a control signal that causes the actuator to extend or retract the permanent magnet from the mu-metal sleeve.

Abstract: Systems and related methods are disclosed for applying electrorheological fluids in hydro-carbon-producing environments. The systems include a fluid-retaining member having a conductive inner surface and a conductive outer surface. The fluid-retaining member retains a smart fluid. The systems also include a controller that is electrically coupled to a power source and at least one of the conductive inner surface and conductive outer surface of the fluid-retaining member to actuate an electric field or magnetic field across fluid-retaining member. Actuation of the electric field or magnetic field results in a near instantaneous increase in the viscosity of the fluid, causing the fluid to solidify, nearly solidify, gel or otherwise increase in viscosity. The actuated fluid retaining member may be used as a well casing, an isolator, a blowout inhibitor, or in a well insulation system to absorb energy in the event of an explosion.
