Abstract
A system and method for selectively stimulating a plurality of producing zones in a wellbore in oil and gas wells. The system includes a plurality of modules connected in a string that may be selectively actuated to stimulate a producing zone. Each module may be adapted to engage a tubing run ball seat. After installation of the string within the wellbore, a ball seat may be run into the well and positioned to selectively engage a desired module. The ball seat may be used to open a sleeve of the module permitting the stimulation of the producing zone. After stimulation of the producing zone, the ball seat may be removed from the wellbore rather than needing to drill out the ball seat. The sleeve may include a profile adapted to engage a shifting tool permitting the selective closure of the sleeve after stimulation of the producing zone.
