US Patent:

7607361, Oct 27, 2009

Filed:

Feb 22, 2008

Appl. No.:

12/035578

Inventors:

Omer Haldun Unalmis - Kingwood TX, US
Espen S. Johansen - Humble TX, US
Leslie Wayne Perry - Kingwood TX, US
Alejandro Vera - Katy TX, US
Daniel Rodriguez - Kingwood TX, US
Vijay Ramakrishnan - Kingwood TX, US

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

G01F 1/42

US Classification:

7386161

Abstract:

Methods and apparatus enable measuring flow of a fluid within a conduit. For example, flowmeters may measure the velocity of production fluid flowing through production pipe of an oil/gas well. The flowmeters rely on detection of pressure variations generated as a result of a backward-facing step as a basis for flow measurement calculations. Pressure sensing occurs away from the step in a direction of the flow of the fluid in an enhanced turbulence region of the flowmeter where the inner diameter remains enlarged as a result of the step.

Appl. No.:

12/025294

Inventors:

Leslie W. Perry - Kingwood TX, US
Espen S. Johansen - Humble TX, US

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

G01F 1/00
G01L 27/00
G06F 7/60

US Classification:

702 45, 73 159, 703 2

Abstract:

Methods and apparatus enable sensing flow of a fluid inside a conduit with an array of pressure or strain sensors. Inputs for a curve fit routine include power correlation values at one of multiple trial velocities or speeds of sound and several steps on either side utilizing data obtained from the sensors. The velocity at which a curve fit routine returns a max curvature result corresponds to an estimate value that facilitates identification of a speed of sound in the fluid and/or a velocity of the flow. Furthermore, a directional quality compensation factor may apply to outputs from the curve fit routine to additionally aid in determining the velocity of the flow.

Filed:

Jul 15, 2003

Appl. No.:

10/619936

Inventors:

John Grisham - Houston TX, US
Michael Meadows - Cypress TX, US
Leslie Perry - Southington CT, US
Alan Sallwasser - Houston TX, US

International Classification:

F25B021/02
F25B027/00
F25D023/12

US Classification:

062003700, 062259200, 062235100

Abstract:

A method, system, and apparatus for controlling the temperature within a remotely located enclosure that contains temperature sensitive equipment is provided. For some embodiments, the system includes an array of thermoelectric cooling (TEC) devices that act as an active cooling device and an active heating device. The system may also include a temperature controller that receives signals from a temperature sensor located at or near the temperature sensitive equipment. The controller may be configured to supply DC power to the thermoelectric coupling devices based on the output signal of the temperature sensor. The polarity of the DC power can be reversed by the controller in order to cause the thermoelectric device to heat or to cool the enclosure. The system also contains a passive cooling device. The system includes an independent electrical power source with a battery and solar cell to supply power to the temperature control devices and the equipment contained in the enclosure.
