  • Patent number: 11933136
    Abstract: A method for operating a circulating sub in a well includes opening a port of the circulating sub, including: dropping a ball into a drill pipe containing a downhole fluid; and seating the ball on an actuator slidably disposed concentrically within the drill pipe, in which seating the ball on the actuator causes motion of the actuator relative to the drill pipe to open a port defined in a wall of the drill pipe. The method includes closing the port of the circulating sub, including: introducing a solvent different from the downhole fluid into the drill pipe, in which a solubility of the ball in the solvent is greater than a solubility of the ball in the downhole fluid; and degrading the ball in the solvent, in which the degrading of the ball causes motion of the actuator relative to the drill pipe to close the port.

  • Patent number: 11898436
    Abstract: A system includes a sliding sleeve, a ball landing seat, a plurality of microchips, a hydraulic piston, and a ball catcher. The sliding sleeve is installed within a tubular body having an exit groove. The ball landing seat is formed by the sliding sleeve. The plurality of microchips are housed in a microchip ring installed within the sliding sleeve. The hydraulic piston is installed within the microchip ring and triggered by reception of a ball in the ball landing seat. The ball reduces a cross sectional area of a flow path while in the ball landing seat. The hydraulic piston releases the plurality of microchips through the exit groove and into the well to gather data. The ball catcher is configured to receive and hold the ball after the plurality of microchips are released into the well. The ball catcher and the ball are made of a dissolvable material.
