Abstract

An insert safety valve system includes a valve body including a valve member. The valve body includes a central passage and a flow path arranged radially outwardly of the central passage. A release sub is coupled to the valve body. The release sub is configured and disposed to support a downhole tool. A connector member selectively couples the release sub and the valve body.

First claim

What is claimed is:

1. An insert safety valve system comprising:
a valve body including a valve member, the valve body including a central passage and a flow path arranged radially outwardly of the central passage;
a release sub coupled to the valve body, the release sub being configured and disposed to support a downhole tool; and
a connector member selectively coupling the release sub and the valve body, the connector member including a stationary portion connected to the valve body and a moveable portion connected to the release sub, the stationary portion including a first connector section including a slot having a non-linear contour and the moveable portion including a second connector section that is selectively coupled to the first connector section.

2. The insert safety valve system according to claim 1 , wherein the slot includes a main section, a first branch section extending annularly outwardly from the main section in a first direction and a second branch section extending annularly outwardly from the main section in a second direction.

3. The insert safety valve system according to claim 2 , wherein the first branch section includes an end wall and the second branch section includes an opening that extends through an axial end of the stationary portion.

4. The insert safety valve system according to claim 2 , wherein the connector member includes a longitudinal axis extending from the valve body through the connector member, the first branch section extending at a first angle relative to the longitudinal axis and the second branch section extending at a second angle relative to the longitudinal axis.

5. The insert safety valve system according to claim 2 , wherein the moveable portion includes a pin member extending into the slot.

6. The insert safety valve system according to claim 5 , further comprising: a biasing element applying a rotational force to the moveable portion, biasing the pin member towards the second branch section.

7. The insert safety valve system according to claim 1 , further comprising: a packing sub arranged between the valve member and the release sub, the packing sub including a selectively radially inwardly expandable packing element.

8. A resource exploration and recovery system comprising:
a first system;
a second system including a tubing retrievable sub-surface safety valve (TRSSSV); and
an insert safety valve system coupled to the TRSSSV, the insert safety valve system comprising:
a valve body including a valve member, the valve body including a central passage and an flow path arranged radially outwardly of the central passage;
a release sub coupled to the valve body, the release sub being configured and disposed to support a downhole tool; and
a connector member selectively coupling the release sub and the valve body, the connector member including a stationary portion connected to the valve body and a moveable portion connected to the release sub, the stationary portion including a first connector section including a slot having a non-linear contour and the moveable portion including a second connector section that is selectively coupled to the first connector section.

9. The resource exploration and recovery system according to claim 8 , wherein the slot includes a main section, a first branch section, and a second branch section, the first branch section including an end wall and the second branch section including an opening that extends through an axial end of the stationary portion.

10. The resource exploration and recovery system according to claim 9 , wherein the moveable portion includes a pin member extending into the slot.

11. The resource exploration and recovery system according to claim 10 , further comprising: a biasing element applying a rotational force to the moveable portion biasing the pin member towards the second branch section.

12. The resource exploration and recovery system according to claim 8 , further comprising: a packing sub arranged between the valve member and the release sub, the packing sub including a selectively radially inwardly expandable packing element.

13. A method of landing an insert safety valve comprising:
shifting an insert safety valve through a tubing retrievable sub-surface safety valve (TRSSSV) of a wellbore;
resting a valve body of the insert safety valve on a landing area of the TRSSSV;
connecting the valve body of the insert safety valve to the TRSSSV;
lifting a conduit coupled to the insert safety valve to disconnect a release sub by biasing a pin member into a branch section od a slot in a connector section, the slot including a non-linear profile, the branch section having an opening: and shifting the conduit in a downhole direction with the release sub.

14. The method of claim 13 , wherein shifting the conduit includes passing the conduit through a packing sub connected with the TRSSSV.

15. The method of claim 14 , further comprising: radially inwardly expanding a packing element of the packing sub to seal against the conduit.
