A flow control and injection arrangement and method

Abstract

A flow control and injection arrangement includes an injection resistant inflow control device in fluid communication with an inside of a production string and with an environment outside the arrangement; and an injection valve in fluid communication with an inside of a production string and with an environment outside the arrangement. The injection valve being responsive to a threshold pressure in the production string to allow fluid flow from inside the production string to the environment outside of the arrangement. A flow control and injection method.

What is claimed is: 
     
         1 . A flow control and injection arrangement comprising:
 an injection resistant inflow control device in fluid communication with an inside of a production string and with an environment outside the arrangement; and   an injection valve in fluid communication with an inside of a production string and with an environment outside the arrangement, the injection valve being responsive to a threshold pressure in the production string to allow fluid flow from inside the production string to the environment outside of the arrangement.   
     
     
         2 . The arrangement as claimed in  claim 1  wherein the device is located within a chamber that is fluidically connected to an environment outside of the arrangement. 
     
     
         3 . The arrangement as claimed in  claim 1  wherein the arrangement includes a sand screen between the environment outside of the arrangement and the production string. 
     
     
         4 . The arrangement as claimed in  claim 1  wherein the injection valve includes a valve stem and valve head. 
     
     
         5 . The arrangement as claimed in  claim 4  wherein the head is seatable on a valve housing to prevent fluid movement through the injection valve. 
     
     
         6 . The arrangement as claimed in  claim 1  wherein the injection valve includes a spring to bias the valve head to a seated position. 
     
     
         7 . The arrangement as claimed in  claim 1  wherein the injection valve further includes a spring housing sealed to a valve housing. 
     
     
         8 . A flow control and injection method comprising:
 producing a selected fluid through an injection resistant inflow control device;   pressuring up on a production string to exceed a threshold pressure in an injection valve; and   opening the injection valve and applying an injection fluid to a formation.
