11/140186

Inventors:

Guy Vachon - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 47/00

US Classification:

16625001, 166386

Abstract:

A flow control device for use in a wellbore to allow flow of formation fluid into the wellbore comprises a valve member adapted to move when disposed in the wellbore. A fluid line supplies a working fluid under pressure to move the valve member to allow the fluid to flow into the wellbore. A sensor in the wellbore, and associated with the fluid line, provides an indication of a position of the valve member. A method of determining a state of a flow control tool within a wellbore comprises supplying fluid under pressure to the flow control tool to move a flow control member of the tool into the state. Pressure of the supplied fluid is detected downhole. The state of the flow control device is determined from the detected pressure of the supplied fluid.

US Classification:

702 6

Abstract:

A system and method is provided for estimating an occurrence of a water breakthrough in a production well that includes estimating, at least periodically, a measure of water in the fluid produced from one or more production zones and estimating the occurrence of the water breakthrough utilizing at least in part a trend of the estimated measures of the produced fluid. A controller determines one or more actions to be taken to mitigate an effect of the water breakthrough and may automatically initiate one or more such actions.

Inventors:

Guy P. Vachon - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 34/16

US Classification:

166374, 166375, 166319, 166386

Abstract:

A system for controlling flow in a wellbore uses a downhole flow control device positioned at a downhole location in the wellbore. The flow control device has a movable element for controlling a downhole fluid flow. In response to an applied pressure pulse, the movable element moves in finite increments from one position to another. In one embodiment, a hydraulic source generates a transmitted pressure pulse to the flow control device wherein the maximum pressure of a received pressure pulse downhole is sufficient to overcome a static friction force associated with the movable element, and wherein a minimum pressure of the received pressure pulse downhole is insufficient to overcome a dynamic friction force associated with the movable element.
