Abstract
A density-based flow control configuration includes a housing and a first baffle having a first flow opening, a second baffle having a second flow opening adjacent the first baffle, one of the baffles being rotationally movable relative to the housing and to the other of the baffles, a first density float associated with the movable baffle, to impart torque to the associated baffle, the torque causing alignment or misalignment of the first and second openings. A method for allowing flow of a target fluid and choking flow of a nontarget fluid, including exposing a density-based flow control configuration to a fluid, imparting torque to a first baffle, and aligning or misaligning an opening in the first baffle with another opening to allow or choke flow of the fluid. A wellbore system, including a density-based flow control configuration.
