US Patent:

20130092373, Apr 18, 2013

Filed:

Oct 17, 2011

Appl. No.:

13/274931

Inventors:

Jose Luis Arellano - Houston TX, US
Kenneth Carmon - Richmond TX, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

E21B 43/00

US Classification:

166267, 166 7512

Abstract:

An apparatus, system, and method are provided for deliquefying a produced fluid being produced from a gas well. The apparatus can be a nozzle configured to be disposed in a production tube extending from a subsurface gas reservoir to a surface location and configured to provide a pathway for transmission of the produced fluid from the reservoir to the surface location. The nozzle generally can define a first end for receiving the produced fluid from the reservoir, a second end distal to the first end, and an inner surface extending between the ends. The inner surface can define an inwardly tapered inlet portion at the first end, an outwardly tapered outlet portion proximate the second end, and a venturi neck portion between the inlet and outlet portions. The nozzle can be configured to reduce the pressure of the produced fluid and thereby deliquefy the produced fluid passing therethrough.

Abstract:

Embodiments of an apparatus, a system, and a method are provided for deliquification of a production well. The apparatus can be a production tube that receives produced fluid from a subterranean reservoir and provides a pathway for transmission of the produced fluid to a surface location. The production tube includes a nozzle disposed therewithin and an opening positioned proximate to the nozzle through which a foaming agent is introduced into the production tube. The nozzle has a first end that defines an inlet, a second end distal to the first end that defines an outlet, and a passageway extending between the first end and the second end such that the produced fluid received by the inlet is delivered to the outlet. The passageway defines a region of decreased cross-sectional area that agitates the produced fluid passing through the nozzle thereby increasing mixing of the foaming agent.
