Filed:

Dec 11, 2012

Appl. No.:

13/711391

Inventors:

CHEVRON U.S.A. INC. - San Ramon CA, US
MASSACHUSETTS INSTITUTE OF TECHNOLOGY - Cambridge MA, US
Donald Bryan Freeman - Houston TX, US
Jose Arellano - Houston TX, US

Assignee:

MASSACHUSETTS INSTITUTE OF TECHNOLOGY - Cambridge MA
CHEVRON U.S.A. INC. - San Ramon CA

International Classification:

F16K 31/12

US Classification:

137468

Abstract:

A valve actuator, valve, and method of actuation of a valve are disclosed. The valve actuator includes a shape memory alloy element attachable to a valve body, capable of use with a valve to cause movement of the valve between first and second positions responsive to at least a threshold amount of temperature change of the shape memory alloy element. The valve actuator further includes a negative-differential spring applied to the shape memory alloy element, thereby reducing the threshold amount of temperature change needed to cause movement of the valve between the first and second positions.

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.

International Classification:

E21B 43/16
E21B 43/14
E21B 43/12

US Classification:

166309, 1662421

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.

International Classification:

E21B 43/12
F16K 17/36
E21B 44/00

US Classification:

137 1, 137468, 1374875

Abstract:

A valve actuator, valve, and method of actuation of a valve are disclosed. The valve actuator includes a shape memory alloy element attachable to a valve body, capable of use with a valve to cause movement of the valve between first and second positions. The valve actuator also includes a sensor located within a well and capable of detecting the presence of a fluid based on a fluid property of the fluid. The valve actuator includes a power supply electrically connected to the sensor and the shape memory alloy element, capable of applying an electric current to the shape memory alloy element in response to the sensor detecting the presence of the fluid. The electric current causes a temperature of the shape memory alloy element to increase beyond a threshold temperature at which the shape memory alloy element actuates.

International Classification:

F16K 31/00

US Classification:

137 2, 137468

Abstract:

A valve actuator, valve, and method of actuation of a valve are disclosed. The valve actuator includes a shape memory alloy element attachable to a valve body, capable of use with a valve to cause movement of the valve between first and second positions at a predetermined temperature and responsive to at least a threshold amount of temperature change of the shape memory alloy element. The valve actuator further includes an expansion element attached to the shape memory alloy element, the expansion element responsive to temperature changes at a rate lower than a rate of change of temperature indicative of a valve leak, the expansion element adjusting tension on the shape memory alloy element, thereby changing the predetermined temperature.
