US Patent:

20110232916, Sep 29, 2011

Filed:

Mar 12, 2011

Appl. No.:

13/046728

Inventors:

Ricardo R. MALDONADO - Carrollton TX, US

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 34/06
E21B 34/00

US Classification:

166373, 166325

Abstract:

An isolation valve can include a pivot connecting a closure member to an actuator member which displaces when the isolation valve is actuated between open and closed configurations, whereby the pivot displaces with the actuator member. Another isolation valve can include a pivot connecting a closure member to an actuator member which displaces when the isolation valve is actuated between open and closed configurations, and a profile formed in the isolation valve. The profile biases the closure member from an open position to a closed position when the isolation valve is actuated from the open configuration to the closed configuration. A method of actuating an isolation valve includes actuating the isolation valve between open and closed configurations, and wherein actuating the isolation valve comprises simultaneously displacing an actuator member, a closure member, and a pivot which pivotably connects the closure member to the actuator member.

US Classification:

166373, 166 666

Abstract:

A method of operating an isolation valve can include transmitting a signal to a detector section of the isolation valve, and a control system of the isolation valve operating an actuator of the isolation valve in response to detection of the signal by the detector section. An isolation valve can include a detector section which detects a presence of an object in the isolation valve, and a control system which operates an actuator of the isolation valve in response to an object presence indication received from the detector section. A well system can include an isolation valve which selectively permits and prevents fluid communication between sections of a wellbore, the isolation valve including a detector section which detects a signal, and the isolation valve further including a control system which operates an actuator of the isolation valve in response to detection of the signal by the detector section.
