Abstract

A fluid loss control valve and packer assembly including a fluid loss control valve, a packer disposed adjacent the fluid loss control valve, a hydraulic opening module operably connected to the valve, and a port associated with the hydraulic opening module and positioned to be exposed to annulus pressure during use. A method for operating a fluid loss control valve in an assembly.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fluid loss control valve and packer assembly comprising:
 a fluid loss control valve;   a packer disposed adjacent the fluid loss control valve;   a hydraulic opening module operably connected to the valve; and   a port associated with the hydraulic opening module and positioned to be exposed to annulus pressure during use.   
     
     
         2 . An assembly as claimed in  claim 1  wherein the loss control valve is a ball valve. 
     
     
         3 . An assembly as claimed in  claim 1  wherein the packer is disposed concentrically with sump space of the valve. 
     
     
         4 . An assembly as claimed in  claim 1  wherein the hydraulic opening module is resettable. 
     
     
         5 . An assembly as claimed in  claim 1  wherein the hydraulic opening module is non-resettable. 
     
     
         6 . An assembly as claimed in  claim 1  wherein the port is connected to the hydraulic opening module via a control line. 
     
     
         7 . An assembly as claimed in  claim 1  wherein the port is connected to the hydraulic opening module via an annular flow space. 
     
     
         8 . An assembly as claimed in  claim 1  wherein the port is connected to the hydraulic opening module through a wall of the module. 
     
     
         9 . A method for operating a fluid loss control valve in an assembly as claimed in  claim 1  comprising:
 moving a piston where differential pressure across the piston is defined by a tubing pressure on one side and annulus pressure uphole of the packer on the other side; 
 counting piston movement cycles with the module; and 
 cycling the valve when a selected number of piston cycles is met. 
 
     
     
         10 . The method as claimed in  claim 9  further including porting annulus pressure uphole of the packer to the module. 
     
     
         11 . The method as claimed in  claim 10  wherein the porting is through a control line. 
     
     
         12 . The method as claimed in  claim 9  wherein the porting is through an annular flow space. 
     
     
         13 . The method as claimed in  claim 9  further including controlling annulus pressure. 
     
     
         14 . The method as claimed in  claim 9  further including cycling annulus pressure. 
     
     
         15 . The method as claimed in  claim 9  further including cycling tubing pressure. 
     
     
         16 . The method as claimed in  claim 9  further including cycling tubing and annulus pressure.
