摘要： A circuit for processing data associated with a well may include a power port that receives an input voltage and a processor. The processor may receive data associated with one or more properties of the well and a well device configured to control a flow of hydrocarbons extracted from the well. The processor may also receive a value that corresponds to the input voltage. The processor may then operate in a first power mode when the value is not greater than a threshold, such that the first power mode may limit one or more processes performed by the processor to conserve power.

摘要： A turbine has a flow pathway with an inlet in communication with the fluid channel. A rotor is disposed in the flow pathway and is rotatable around a rotation axis under the action of fluid flowing along the flow pathway. The rotation axis of the rotor is oblique to an axis extending along the fluid channel. The outlet of flow pathway may return fluid to the fluid channel. The turbine may also be provided with a flow control arrangement so as to vary the flow of fluid past the rotor and to prevent the rotor from damage. The rotor may be positioned apart from the fluid channel and so as not to obstruct the fluid channel.

摘要： A pressure reduction turbine for a hydrocarbon well stream driving a hydraulic pump, and the turbine has two cog wheels mounted laterally to a well stream. A deflector plate is positioned at the well inlet to split and direct the well stream towards the outsides of the cogwheels and to drive them with opposite rotation. The turbine is designed to give a large pressure drop. Ceramics is used in the turbine housing, in the turbine inlet and in the turbine outlet, to withstand erosion wear. A hydraulic pump is supplied with collective torque via the turbine shaft, supported by two journal bearings and is connected to the pump via a dynamic sealing arrangement. Alternatively the torque from the turbine may be transmitted by to the pump without the dynamic seal, via a magnet coupling. In an underwater implementation the turbine with the pump are equipped with an arrangement for connection or disconnection via an underwater tool system, so that the equipment may be pulled and installed from a surface vessel. The hydraulic pump leads hydraulic oil at high pressure out into a piping system where hydraulic energy, possibly from several such power sources, is led to a common hydraulic motor driving an electric generator. In a surface implementation the generator is positioned in a non-explosive environment, for example in an overpressure container.
