摘要： An assembly includes a housing of a production tubing including one or more housing ports around a housing circumference of the housing. The assembly also includes a sleeve including one or more sleeve ports around a sleeve circumference of the sleeve. The sleeve is moveable between a closed configuration in which at least a portion of the sleeve is positionable to cover the housing ports of the production tubing and an open configuration in which the sleeve is positionable such that the sleeve ports provide fluid communication between the production tubing and an annulus in a wellbore. Further, the assembly includes a shoulder positioned at an uphole edge of the sleeve to apply an opening force to the sleeve to change the sleeve from the closed configuration to the open configuration.
