Diverter plug for blocking fluid flow in wells
The granted patent US12065899B2 outlines a method for deploying a diverter plug into a well, which is designed to manage fluid flow through a fluid passageway. The diverter plug consists of a group of particles contained within an outer enclosure, along with at least one enlarged body that is too large to pass through the fluid passageway. As fluid flows in the well, the diverter plug is conveyed into engagement with the passageway, where the particles conform to the shape of the passageway, effectively blocking fluid flow. The claims detail various configurations of the diverter plug, including the presence of a line or fibers extending outwardly from the enclosure, and the potential for the particles and enclosure to degrade over time within the well.
Further claims specify additional features of the diverter plug, such as the ability for the particles to be loose within the enclosure during deployment, and the use of flexible sheet materials or fabric sheets to retain the particles. The method also allows for the production of fluid drag on materials extending outwardly from the diverter plug, enhancing its effectiveness in sealing the fluid passageway. Notably, the patent includes provisions for multiple enlarged bodies and their securement within the enclosure, as well as the specific design of the enlarged body, which may include a knot formed in a line. Overall, the patent presents a comprehensive approach to utilizing diverter plugs in well operations, focusing on their structural and functional characteristics to optimize fluid management.
