Abstract: An inflow control nozzle is provided for use with a tubing. The nozzle includes a one-piece, 3D printed body, the body including a fluid inlet in communication with an outside of the tubing said inlet having an oval cross section; a fluid outlet in communication with an inside of the tubing; and an inner bore connecting the fluid inlet to the fluid outlet, said inner bore including a venturi restriction. The inner bore comprises a flared profile from the fluid inlet to the venturi restriction, and a flared and curved profile from the venturi restriction to the fluid outlet, said curved profile being free of angular bends or sharp direction change. An outflow control nozzle is also provided for use with a tubing and an inflow-outflow control nozzle is further provided for use with a casing.

Abstract: A device is provided for delivering and distributing injection fluids into a subsurface formation from a horizontal wellbore. The device includes one or more steam pups having an outer sleeve and an inner sliding sleeve in concentric relationship. One or more sets of nozzles are arranged on the outer sleeve. A means is provided for actuating movement of the inner sliding sleeve within the outer sleeve, to at least partially cover one or more sets of nozzles on the outer sleeve. A method is also provided for delivering injection fluids into a subsurface formation from a horizontal wellbore. First, one or more steam pups are introduced into the horizontal well, said steam pups having an outer sleeve and an inner sliding sleeve with one or more sets of nozzles arranged on the outer sleeve. Next the inner sliding sleeve is moved inside the outer sleeve to at least partially cover one or more sets of nozzles on the outer sleeve. Finally, injection fluid is injected through the steam pup nozzles into formation.
