Treatment ported sub and method of use

A ported sub integrates a seat for an object to land on to allow pressure buildup. A sleeve shifts with the ball and the seat to open ports that are screened. The openings feature hardened inserts to control wear from high velocity fluid. The interval is treated through such openings with treatment fluid that is relatively free of solids. The formation is produced through the same screened inserts that were used for treating. The sleeve can be releasably retained in the ports open position and can optionally be closed with well intervention such as with a shifting tool. The object can pass through the seat after sleeve shifting by disintegration or by using a segmented seat that opens enough to allow the object to pass. An array can be spaced throughout the zone for treating or fracturing and the sleeves shifted bottom up using different or same sized balls.
