Abstract
The present application describes methods and systems for a tool with a new check valve. The check valve may include a piston sleeve that is configured to move towards the proximal end of the tool to seal restrictive ports in a center of the tool responsive to creating a force on the piston sleeve. In embodiments, the movement of the piston sleeve may be counter to the flow of fluid through an inner diameter of the tool, such that the tool may be resettable and repeatable based on fluid flow and/or pressure differentials and not based on drag force through an inner diameter of the tool.
Claims20
A fracturing system comprising:
- a tool with an inner diameter extending from a distal end of the tool to a proximal end of the tool;
- restrictive ports configured to allow or restrict a flow of fluid through the inner diameter of the tool, the restrictive ports being positioned between the proximal end and the distal end;
- a piston sleeve configured to move within the inner diameter of the tool, the piston sleeve being configured to move in an opposite direction of the flow of fluid through the inner diameter of the tool.
A fracturing method comprising:
- positioning a tool within a geological formation, the tool including an inner diameter extending from a distal end of the tool to a proximal end of the tool;
- controlling a flow of fluid through the inner diameter of the tool via restrictive ports, the restrictive ports being positioned between the proximal end and the distal end;
- moving a piston sleeve within the inner diameter of the tool in an opposite direction of the flow of fluid through the inner diameter of the tool.
