Embodiments described herein provide methods and apparatus to determine water-to-liquid ratio and water volume fraction for high gas-volume-fraction wet-gas flows or multiphase flows.

A fluid sensor, and associated monitoring and control system, employing a cylindrical venturi to eliminate stratification of fluid passing therethrough, and a capacitive sensor operatively coupled with the cylindrical venturi to facilitate the sensing of the fluid while in the venturi.

A flowmeter may include an inlet configured to couple to a first conduit to receive a flow of a multiphase medium, an outlet configured to couple to a second conduit to deliver the multiphase medium, and a chamber extending between the inlet and the outlet and providing a flow path between the inlet and the outlet. The flowmeter may include a device within the chamber. The device may be configured to move in response to the multiphase medium to dynamically vary an effective constriction ratio of the flow path. The flowmeter may include a circuit configured to determine a flow rate of the multiphase medium based on the effective constriction ratio.

A support arm can be positioned in an inner area of a tubular body. The support arm can extend from the inner surface of the tubular body to retain a sensor in flow from a wellbore blowout passing through the tubular body.

A system and method for metering fluid flow is disclosed which has improved diagnostic capabilities. As well as informing a flow meter operator of the presence of a malfunction and its likely cause, the new systems and methods can also quantify an associated flow prediction bias.

A wellhead system includes a wellhead, a fluid line extending from the wellhead, a branch line fluidly connected to the fluid line at an inlet and at an outlet, an ejector device arranged on the branch line, a tank fluidly connected by a tank fluid line to the ejector device, and a pressure control valve arranged on the branch line upstream of the ejector device. The ejector device is configured to produce a mixture that includes the fluid from the wellhead flowing in the branch fluid line with a chemical flowing the tank fluid line. The ejector device is also configured to discharge the mixture downstream of the ejector device. The pressure control valve is configured to control the flow of a fluid entering the ejector device.
