Mechanically lockable and unlockable hydraulically activated valve, borehole system and method

Abstract

A mechanically lockable and unlockable hydraulically activated valve including a mechanical component having a locked position and an unlocked position, a hydraulic component in operational communication with the mechanical component, the hydraulic component including a portion that is unresponsive to pressure events with the mechanical component in the locked position and responsive to pressure events with the mechanical component in the unlocked position. A borehole system including a string disposed within a borehole, the string including a valve. A method of operating a mechanically lockable and unlockable hydraulically activated valve for a borehole includes shifting a mechanical component of the mechanically lockable and unlockable hydraulically activated valve from a locked position to an unlocked position, inducing a differential pressure on a hydraulic component of the mechanically lockable and unlockable hydraulically activated valve, opening a hydraulic valve of the mechanically lockable and unlockable hydraulically activated valve.

What is claimed is: 
     
         1 . A mechanically lockable and unlockable hydraulically activated valve comprising:
 a mechanical component having a locked position and an unlocked position;   a hydraulic component in operational communication with the mechanical component, the hydraulic component including a portion that is unresponsive to pressure events with the mechanical component in the locked position and responsive to pressure events with the mechanical component in the unlocked position.   
     
     
         2 . A valve as claimed in  claim 1  wherein the hydraulic component is resettable based upon a movement of the mechanical component from the unlocked position to the locked position. 
     
     
         3 . A valve as claimed in  claim 1  wherein the mechanical component comprises a sleeve, and a mandrel movable therewith. 
     
     
         4 . A valve as claimed in  claim 3  wherein the sleeve further includes a profile configured to be engagable by a shifting tool. 
     
     
         5 . A valve as claimed in  claim 4  wherein the profile is selective. 
     
     
         6 . A valve as claimed in  claim 1  wherein the hydraulic component comprises a piston having an interlock feature configured to connect the piston to a hydraulic valve. 
     
     
         7 . A valve as claimed in  claim 6  wherein the hydraulic component further includes a resilient member interactive with the piston. 
     
     
         8 . A valve as claimed in  claim 6  wherein the piston is receptive of a mandrel portion of the mechanical component, the mandrel component when the mechanical component is in the locked position preventing movement of the hydraulic valve. 
     
     
         9 . A valve as claimed in  claim 8  wherein the mandrel position either allows or prevents operation of the interlock feature. 
     
     
         10 . A valve as claimed in  claim 1  further including a screen. 
     
     
         11 . A valve as claimed in  claim 1  wherein the hydraulic component further includes an indexing configuration. 
     
     
         12 . A valve as claimed in  claim 1  wherein the indexing configuration is a J-slot. 
     
     
         13 . A borehole system comprising:
 a string disposed within a borehole, the string including a valve as claimed in  claim 1 .   
     
     
         14 . A method of operating a mechanically lockable and unlockable hydraulically activated valve for a borehole comprising:
 shifting a mechanical component of the mechanically lockable and unlockable hydraulically activated valve from a locked position to an unlocked position;   inducing a differential pressure on a hydraulic component of the mechanically lockable and unlockable hydraulically activated valve;   opening a hydraulic valve of the mechanically lockable and unlockable hydraulically activated valve.   
     
     
         15 . The method of operating a mechanically lockable and unlockable hydraulically activated valve as claimed in  claim 14  further comprising reshifting the mechanical component from the unlocked position to the locked position. 
     
     
         16 . The method of operating a mechanically lockable and unlockable hydraulically activated valve as claimed in  claim 15  wherein the reshifting includes mechanically closing the hydraulic valve with the mechanical component. 
     
     
         17 . The method of operating a mechanically lockable and unlockable hydraulically activated valve as claimed in  claim 14  wherein the opening is by reducing applied pressure. 
     
     
         18 . The method of operating a mechanically lockable and unlockable hydraulically activated valve as claimed in  claim 14  wherein the opening includes permitting movement due to expansion of a resilient member. 
     
     
         19 . The method of operating a mechanically lockable and unlockable hydraulically activated valve as claimed in  claim 14  wherein the inducing is more than one time before opening of the hydraulic valve. 
     
     
         20 . The method of operating a mechanically lockable and unlockable hydraulically activated valve as claimed in  claim 14  wherein the inducing cycles a J-slot configuration.
