Jarring tool for subterranean well with fluid flow control
A recently granted patent (Publication Number: US11993994B2) discloses a jarring tool designed for use in subterranean wells. The tool includes a piston that can move from a first to a second position, a first fluid chamber with a decreasing volume, a flow controller regulating fluid flow between chambers, and a plug seat for receiving a plug when activation is required. The tool's design allows for controlled pressure differentials and flow rates to apply a jarring force to equipment stuck in the well.
The patented method involves introducing a plug into the jarring tool, engaging it with the plug seat, and applying a pressure differential to build pressure within the tool. By controlling the displacement rate of the piston and increasing fluid flow, the jarring force is applied to the stuck equipment. Various techniques such as discharging the plug, eroding it, or expanding the plug seat are employed to increase flow rates and release the plug. The method also includes deploying the jarring tool into a tubular string in the well and engaging it with another tool for enhanced effectiveness in freeing stuck equipment. Overall, the patented jarring tool and method offer a precise and efficient solution for addressing equipment obstructions in subterranean wells.
