SUB SURFACE SAFETY VALVE
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.
