An interventionless stimulation and production system includes a housing and a stimulation sleeve. The stimulation sleeve includes a first diverter seat, and a second diverter seat initially having a smaller diameter, where the first diverter seat is configured to permit a first diverter to pass through the first diverter seat and prevent a second diverter having a larger diameter from passing through the first diverter seat, the second diverter seat is initially configured to prevent the first diverter from passing through the second diverter seat, and landing the first diverter onto the second diverter seat shifts the stimulation sleeve from a first position to a second position to initiate a stimulation operation. The stimulation also includes a production sleeve that is initially in a closed position, where the production sleeve is configured to shift to an open position after the second diverter lands on the first diverter seat.

Interventionless stimulation and production systems, multi-zone interventionless stimulation and production assemblies, and methods to perform interventionless stimulation and production operations

An assembly comprises a tubular housing having a bore therethrough and at least one stimulation port therein to communicate fluid from the bore to outside the tubular housing and a sleeve axially movable in the tubular housing. The sleeve comprises a first baffle and a second baffle. The sleeve is initially in a first closed position, wherein the sleeve is to axially move from the first closed position to an open position in response to the first baffle receiving a first object therein, wherein the at least one stimulation port is open in the open position. The sleeve is to axially move from the open position to a second closed position in response to the second baffle receiving a second object received therein, wherein the second object is larger than the first object, where the at least one stimulation port is closed in the second closed position.
