A nozzle for controlling the flow of a water and/or gas component of a fluid produced from a hydrocarbon-bearing reservoir, the fluid comprising oil and water and/or gas, the nozzle comprising a fluid passage extending between an inlet and an outlet, wherein the fluid passage comprises an uneven surface for imparting turbulence to the water and/or gas component of the fluid.

Nozzle for water choking

A flow control system includes a nozzle for controlling the flow of fluids into production tubing from a hydrocarbon containing reservoir. The nozzle comprises a passage extending between an inlet and an outlet, wherein the passage comprises converging and diverging sections separated by a corner. The nozzle serves to effectively choke the flow of steam and thereby allows preferential production of hydrocarbons.

Flow control nozzle and system

A nozzle for controlling the flow of fluids into and/or out of a hydrocarbon-bearing reservoir comprises a fluid passage extending between first and second openings. The passage comprises a flow adjusting region for increasing the velocity of fluids injected into the reservoir and for choking steam produced from the reservoir.

Nozzle for steam injection and steam choking

A nozzle for mitigating against solvent flashing in a solvent-assisted hydrocarbon extraction process comprises a fluid passage extending between an inlet and an outlet, wherein the fluid passage comprises a converging region, a throat, and a diverging region, and wherein at least the converging region is provided with a gradually reducing internal diameter. Preferably, the angle of convergence of the converging region is equal to or less than about 5 degrees.

Production nozzle for solvent-assisted recovery

A steam injection nozzle for controlling the flowrate of steam injected into a hydrocarbon containing reservoir comprises a passage extending between an inlet and an outlet, wherein the passage comprises a first, pressure dissipating section and a second, pressure recovery section.

Nozzle for steam injection

A flow control nozzle for regulating flow of fluid into a pipe comprises a body having a portion that is adapted to be received within an opening in the pipe, wherein the body includes a channel extending from an inlet to an outlet opening into the pipe. The channel includes a first section extending from the inlet and a second section extending to the outlet, wherein the first and second sections are connected at an elbow and wherein the first section has a constant cross-sectional area and the second section has a diverging cross-sectional area. An apparatus comprising the flow control nozzle and a base pipe and a screen.
