  • Patent number: 11952886
    Abstract: A method and system are described for communicating within a system, which includes a plurality of communication nodes disposed along tubular members in a wellbore. The method includes constructing a communication network and installing the communication nodes along the tubular members. The communication nodes are used to monitor for the presence and/or quantity of sand in the tubular members by analyzing how the contents of the tubular members acoustically affect the signals transmitted between the communication nodes.

  • Patent number: 11555378
    Abstract: A self-destructible frac ball is described herein. The self-destructible frac ball is configured to seal a hydraulic flow path through a fluid conduit of a frac plug when engaged on a ball seat of the frac plug. The self-destructible frac ball includes an activation mechanism configured to activate a destructive medium in response to the satisfaction of at least one predetermined condition. The self-destructible frac ball also includes the destructive medium, which is configured to destroy the self-destructible frac ball and a corresponding destructible ball retainer when activated by the activation mechanism. The destruction of the self-destructible frac ball and the corresponding destructible ball retainer reestablishes the hydraulic flow path through the fluid conduit of the frac plug.
