Tension-activated fluid bypass device and associated method
View Patent ↗A fluid bypass tool that can be incorporated into a fishing arrangement between a fluid-operated latching tool and a fluid-operated jarring tool. The latching tool is actuated with fluid from the surface to be latched to and unlatched from a stuck tool in the wellbore. The bypass tool permits fluid flow to the latching tool to be interrupted so that the jarring tool may be operated without risk of inadvertently causing the latching tool to unlatch from the stuck tool.
1. A fluid bypass tool to be incorporated into a wellbore fishing arrangement having a fluid-operated jarring tool and a fluid-operated latching tool, the fluid bypass tool comprising:
a first tool section that is operably connected with the jarring tool;
a second tool section that is operably connected with the latching tool; and
the first and second tool sections being selectively moveable with respect to each other between a first condition, wherein an operating fluid flow through the fishing arrangement to the latching tool is permitted, and a second condition, wherein the operating fluid flow to the latching tool is blocked.
2. The fluid bypass tool of claim 1 wherein the first and second tool sections are moved from the first condition to the second condition by applying tension upon the first and second tool sections.
3. The fluid bypass tool of claim 1 wherein the first and second tool sections are spring-biased toward the first condition.
4. The fluid bypass tool of claim 1 wherein a central axial flowbore is defined within the first and second tool sections to permit fluid to flow axially through the bypass tool.
5. The fluid bypass tool of claim 1 wherein, in the second condition, fluid flow through the fishing arrangement is expelled radially outwardly into a surrounding wellbore.
6. A fluid bypass tool to be incorporated into a wellbore fishing arrangement having a fluid-operated jarring tool and a fluid-operated latching tool, the fluid bypass tool comprising:
a first tool section that is operably connected with the jarring tool;
a second tool section that is operably connected with the latching tool;
the first and second tool sections being selectively moveable with respect to each other between a first position, wherein an operating fluid flow through the fishing arrangement to the latching tool is permitted, and a second position, wherein the operating fluid flow to the latching tool is blocked; and
wherein the first and second tool sections are moved from the first condition to the second condition by applying tension upon the first and second tool sections.
7. The fluid bypass tool of claim 6 wherein the first and second tool sections are spring biased toward the first condition.
8. The fluid bypass tool of claim 6 wherein a central axial flowbore is defined within the first and second tool sections to permit fluid to flow axially through the bypass tool.
9. The fluid bypass tool of claim 6 wherein, in the second condition, fluid flow through the fishing arrangement is expelled radially outwardly into a surrounding wellbore.
10. A fishing arrangement for removing a stuck object from a wellbore, the fishing arrangement comprising:
a fluid-operated jarring tool;
a fluid-operated latching tool; and
a fluid bypass tool comprising:
a) a first tool section that is operably connected with the jarring tool;
b) a second tool section that is operably connected with the latching tool; the first and second tool sections being selectively moveable with respect to each other between a first condition, wherein an operating fluid flow through the fishing arrangement to the latching tool is permitted, and a second condition, wherein the operating fluid flow to the latching tool is blocked.
11. The fishing arrangement of claim 10 wherein the wherein the first and second tool sections are spring-biased toward the first condition.
12. The fishing arrangement of claim 10 wherein a central axial flowbore is defined within the first and second tool sections to permit fluid to flow axially through the bypass tool.
13. The fishing arrangement of claim 10 wherein, in the second condition, fluid flow through the fishing arrangement is expelled radially outwardly into a surrounding wellbore.
14. The fishing arrangement of claim 10 wherein the first and second tool sections are moved from the first condition to the second condition by applying tension upon the first and second tool sections.
15. A method of removing a stuck object from a wellbore with a fishing arrangement comprising the steps of:
disposing a fishing arrangement into the wellbore, the fishing arrangement having a fluid-operated jarring tool, a fluid-operated latching tool, and a fluid bypass tool operably connected with the jarring tool and the latching tool, the fluid bypass tool having:
a) a first tool section that is operably connected with the jarring tool;
b) a second tool section that is operably connected with the latching tool;
c) the first and second tool sections being selectively moveable with respect to each other between a first condition, wherein an operating fluid flow through the fishing arrangement to the latching tool is permitted, and a second condition, wherein the operating fluid flow to the latching tool is blocked;
latching the latching mechanism to the stuck object;
actuating the bypass tool to divert fluid flow from entering the latching tool; and
operating the jarring tool to remove the stuck object.
16. The method of claim 15 wherein the step of actuating the bypass tool comprises applying tension to the fishing arrangement to move the bypass tool to the second condition.
