Sub surface safety valve

Abstract

According to the present invention, there is provided a sub surface safety valve in a well system comprising an upper support means, a sub surface safety valve, a sealing means that seals against the inside of the production path and a bore through the sub surface safety valve and sealing means which connects to an annular inlet beneath the sealing means and an annular outlet above the sub surface safety valve.

1 . A sub surface safety valve in a well system comprising
 an upper support means   a sub surface safety valve   a sealing means that seals against an inside of a production path   and a bore through the sub surface safety valve and sealing means which connects to an annular inlet beneath the sealing means and an annular outlet above the sub surface safety valve.   
     
     
         2 . A sub surface safety valve system according to  claim 1  wherein a lower power cable hangs from a packer down the well, the lower power cable being conductively connected to an upper power connector. 
     
     
         3 . A sub surface safety valve system according to  claim 1  wherein a lower power cable includes a support means. 
     
     
         4 . A sub surface safety valve system according to  claim 2  wherein the lower power cable includes a support means. 
     
     
         5 . A sub surface safety valve system according  claim 1  wherein an upper power cable includes conductors that provide a support means. 
     
     
         6 . A sub surface safety valve system according  claim 2  wherein an upper power cable includes conductors that provide a support means. 
     
     
         7 . A sub surface safety valve system according  claim 3  wherein an upper power cable includes conductors that also provide the support means. 
     
     
         8 . A sub surface safety valve system according to  claim 1  wherein a lower power cable includes conductors that provide a support means. 
     
     
         9 . A sub surface safety valve system according to  claim 2  wherein the lower power cable includes conductors that provide a support means. 
     
     
         10 . A sub surface safety valve system according to  claim 3  wherein a lower power cable includes conductors that provide a support means. 
     
     
         11 . A sub surface safety valve system according to  claim 5  wherein a lower power cable includes conductors that also provide a support means. 
     
     
         12 . A sub surface safety valve system according to  claim 2  wherein an upper power cable and lower power cable are connected via at least one metal tube that passes through and is sealed against the packer. 
     
     
         13 . A sub surface safety valve system according to  claim 3  wherein an upper power cable and the lower power cable are connected via at least one metal tube that passes through and is sealed against the packer. 
     
     
         14 . A sub surface safety valve system according to  claim 5  wherein the upper power cable and a lower power cable are connected via at least one metal tube that passes through and is sealed against a packer. 
     
     
         15 . A sub surface safety valve system according to  claim 8  wherein an upper power cable and the lower power cable are connected via at least one metal tube that passes through and is sealed against a packer.
