Resettable configurable intercept sub surface control valve
Systems and methods of the present disclosure relate to shifting mandrels in downhole tools based on hydraulic pressure. A downhole tool includes an outer sleeve, an inner mandrel and a valve plate coupled to the inner mandrel. The valve plate and the inner mandrel are configured to shift axially within the outer sleeve. The valve plate is further configured to pass a portion of fluid through the valve plate and pass another portion of the fluid around the valve plate, based on a tensile force or a compressive force exerted on the downhole tool.
1 . A downhole tool comprising:
an outer sleeve;
a tapered portion on an interior portion of the outer sleeve;
an inner mandrel; and
a valve plate coupled to the inner mandrel, the valve plate and the inner mandrel configured to shift axially within the outer sleeve such that the valve plate moves axially along the tapered portion, the valve plate further configured to pass a portion of fluid through the valve plate when a tensile force is applied to the inner mandrel and pass another portion of the fluid around the valve plate and through the tapered portion when a compressive force is applied on the downhole tool.
2 . The downhole tool of claim 1 , wherein the valve plate includes a relief valve.
3 . The downhole tool of claim 1 , wherein a seal is disposed between the valve plate and an interior of the outer sleeve and adjacent to the tapered portion.
4 . The downhole tool of claim 1 , further comprising a ball disposed in the downhole tool, the ball configured to shift in the downhole tool upon shifting of the inner mandrel and the valve plate.
5 . The downhole tool of claim 1 , wherein the valve plate is disposed between two sections of a chamber filled with the fluid.
6 . The downhole tool of claim 1 , wherein the valve plate is configured to open or close based on pressure exerted on the valve plate by the fluid.
7 . The downhole tool of claim 1 , further comprising a piston movably disposed on the inner mandrel.
8 . The downhole tool of claim 7 , wherein the piston separates the fluid from a wellbore fluid.
9 . A method comprising:
applying a compressive force or a tensile force to a downhole tool to shift an inner mandrel of the downhole tool, the tool including:
an outer sleeve;
an inner mandrel; and
a valve plate coupled to the inner mandrel, the valve plate and the inner mandrel configured to shift axially within the outer sleeve, the valve plate further configured to pass a portion of fluid through the valve plate when a tensile force is applied to the inner mandrel and pass another portion of the fluid around the valve plate and through a tapered portion when a compressive force is applied to the inner mandrel.
10 . The method of claim 9 , wherein the fluid is a bath oil.
11 . The method of claim 9 , wherein the valve plate includes a relief valve.
12 . The method of claim 11 , wherein the valve plate is configured to open or close based on pressure exerted on the valve plate by the fluid.
13 . The method of claim 12 , further comprising shifting a ball in the downhole tool upon shifting of the inner mandrel and the valve plate.
14 . The method of claim 13 , wherein the valve plate includes a seal that is disposed between the outer sleeve and the valve plate.
15 . The method of claim 13 , wherein the valve plate is disposed between two sections of a chamber filled with the fluid.
16 . The method of claim 15 , further comprising a piston movably disposed on the inner mandrel.
17 . The method of claim 16 , wherein the piston separates the fluid from a wellbore fluid.
18 . A downhole tool comprising:
an outer sleeve;
a tapered portion on an interior portion of the outer sleeve;
an inner mandrel;
a first fluid chamber comprising a fluid;
a second fluid chamber comprising the fluid and fluidically coupled to the first fluid chamber;
a valve plate positioned in between the first fluid chamber and second fluid chamber such that a portion of the fluid can pass through the valve plate when a tensile force is applied to the inner mandrel while another portion of the fluid may pass around the valve plate when a compressive force is applied to the inner mandrel; and
a balancing piston separating the first fluid chamber from a well fluid chamber.
19 . The downhole tool of claim 18 wherein:
the valve plate travels axially along the tapered portion when the inner mandrel moves.
20 . The downhole tool of claim 18 wherein:
the valve plate is pushed by the inner mandrel past the tapered portion to allow fluid to pass around the valve plate.
