US Patent:

7934433, May 3, 2011

Filed:

Nov 4, 2009

Appl. No.:

12/612458

Inventors:

Juan P. Franco - Houston TX, US
Kanti D. Lad - Sugar Land TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

G01F 1/44

US Classification:

7386163

Abstract:

An insert meter can be run into an inverse venturi on wireline and make use of the existing pressure taps to allow accurate measurement of reduced flow rates that could not be accurately measured with the inverse venturi meter. The insert meter has seals and can lock into position with peripheral sealing to direct the new and lower flow rate into the throat of the insert meter that is preferably a standard venturi. The venturi devices can be in meter or eductor service and located downhole, subsea or on the surface.

International Classification:

US Classification:

Abstract:

The position of a movable downhole component such as a sleeve in a choke valve is monitored and determined using an array of sensors, preferably Hall Effect sensors that measure the strength of a magnetic field from a magnet that travels with the sleeve. The sensors measure the field strength and output a voltage related to the strength of the field that is detected. A plurality of sensors, with readings, transmits signals to a microprocessor to compute the magnet position directly. The sensors are in the tool body and are not mechanically coupled to the sleeve. The longitudinal position of the sleeve is directly computed using less than all available sensors to facilitate the speed of transmission of data and computation of actual position using known mathematical techniques.

Appl. No.:

11/827035

Inventors:

Juan P. Franco - Houston TX, US
Michael A. Unger - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 34/06

US Classification:

166373, 1663321

Abstract:

An annular choke mechanism is incorporated into a flow path within the outer housing of the sleeve valve to the interior flow ports of the sliding sleeve member. As the sliding sleeve member is moved axially within the housing, the lateral fluid ports of the sliding sleeve member are aligned within particular bore portions so that the size of the annular space between the fluid ports in the housing and the fluid ports in the sleeve is varied. The annular flow area through the annular space governs the rate of fluid flow through the valve.
