Abstract

A subsurface safety valve tool includes a body having an upper portion positioned upstream of a subsurface safety valve and a lower portion that extends into and through the an interior bore and a hinged valve of the subsurface safety valve, and at least one protrusion extending from an exterior surface of the upper portion of the body, such that the at least one protrusion abuts a fishneck of the subsurface safety valve when the body is positioned within the interior bore of the subsurface safety valve. The subsurface safety valve tool prevents the subsurface safety valve from translating from an open position to a closed position when the subsurface safety valve tool is positioned within the interior bore of the subsurface safety valve.

Claims (30)

1 . A subsurface safety valve comprising:

an interior bore extending along an entire length of the subsurface safety valve;

a hinged valve actuatable between an open position and a closed position, wherein the hinged valve creates a fluid-tight seal with the interior bore in the closed position; and

a fishneck formed at an uppermost end of the subsurface safety valve and having at least a portion of a subsurface safety valve tool received therein, wherein the subsurface safety valve tool comprises:

a body having an upper portion positioned upstream of the subsurface safety valve and a lower portion that extends into and through the interior bore and hinged valve of the subsurface safety valve; and

at least one protrusion extending from an exterior surface of the upper portion of the body, such that the at least one protrusion rests atop the fishneck of the subsurface safety valve when the body is positioned within the interior bore of the subsurface safety valve;

wherein the subsurface safety valve tool prevents the subsurface safety valve from translating from the open position to the closed position when the subsurface safety valve tool is positioned within the interior bore of the subsurface safety valve.

2 . The subsurface safety valve of claim 1 , further comprising a control line for controlling the subsurface safety valve at a surface of a wellbore.

3 . The subsurface safety valve of claim 1 , wherein the body of the subsurface safety valve tool is a hollow body.

4 . The subsurface safety valve of claim 1 , wherein the subsurface safety valve tool is installed in a wellbore via a wireline.

5 . The subsurface safety valve of claim 1 , wherein the body of the subsurface safety valve tool includes a cone-shaped profile.

6 . The subsurface safety valve of claim 1 , wherein the lower portion of the body of the subsurface safety valve tool is made of brass.

7 . The subsurface safety valve of claim 1 , wherein the body of the subsurface safety valve is a stainless steel body.

8 . A subsurface safety valve tool for a subsurface safety valve, the subsurface safety valve tool comprising:

at least one protrusion extending from an exterior surface of the upper portion of the body, such that the at least one protrusion rests atop a fishneck formed at an uppermost end of the subsurface safety valve when the body is positioned within the interior bore of the subsurface safety valve.

9 . The subsurface safety valve tool of claim 8 , wherein the subsurface safety valve tool locks the subsurface safety valve in an open position when the subsurface safety valve tool is positioned within the subsurface safety valve.

10 . The subsurface safety valve tool of claim 8 , wherein the body of the subsurface safety valve tool is a hollow body.

11 . The subsurface safety valve tool of claim 8 , wherein the subsurface safety valve tool is installed in a wellbore via a wireline.

12 . The subsurface safety valve tool of claim 8 , wherein the body of the subsurface safety valve tool includes a cone-shaped profile.

13 . The subsurface safety valve tool of claim 8 , wherein the lower portion of the body of the subsurface safety valve tool is made of brass.

14 . A method of locking a subsurface safety valve, the method comprising:

positioning the subsurface safety valve having an interior bore into a wellbore;

translating a valve of the subsurface safety valve from a closed position to an open position;

coupling a subsurface safety valve tool having a body including an upper portion and a lower portion to a wireline;

positioning the subsurface safety valve tool within the interior bore of the subsurface safety valve, such that the subsurface safety valve tool extends through the valve and at least one protrusion formed on the upper portion of the body of the subsurface safety valve tool rests atop a fishneck formed at an uppermost end of the subsurface safety valve;

testing an integrity of the coupling between the subsurface safety valve tool and the subsurface safety valve;

decoupling the wireline from the subsurface safety valve tool; and

removing the wireline from the wellbore.

15 . The method of claim 14 , wherein the subsurface safety valve tool is positioned within the interior bore of the subsurface safety valve such that the upper portion of the body of the subsurface safety valve tool extends out of the interior bore and the lower portion of the body of the subsurface safety valve extends through the interior bore.
