Fracture tool for subsurface formation fluid production
The granted patent US12071839B2 describes a fracture tool and a fracture and production system designed for use in subsurface formations. The fracture tool features a housing with a fracture port and an inflow port, along with a movable fracture sleeve that can block or unblock the fracture port. The tool includes a biaser, such as a spring, that maintains the sleeve in a closed position until pressure is applied. Additionally, a valve sleeve within the housing can be shifted to open the inflow port, while a pressure-activated valve remains in an unarmed condition until it is triggered by the valve sleeve. The design allows for the establishment of a pressure differential across a seat in the sleeve, facilitating the movement of the sleeve and the operation of the valve.
The patent also outlines a method for fracturing formations and producing fluids, which involves opening the fracture sleeve, shifting the pressure-operated valve from an unarmed to an armed position, and applying fracture pressure. The method allows for the automatic closing of the fracture sleeve and the actuation of the valve to enable fluid flow. Furthermore, the borehole system described in the patent can incorporate multiple fracture and production systems, allowing for sequential actuation of fracture sleeves and simultaneous operation of valves. This innovative design aims to enhance the efficiency and effectiveness of fluid production in subsurface formations.
