Patent ID: 7575062

Claim:
A method for multi-interval fracturing treatment comprising the steps of: (a) introducing a multi-interval fracture treatment isolation assembly to a wellbore, the multi-interval fracture treatment isolation assembly comprising a liner, a first fluid communication port, a first sleeve movable relative to the first fluid communication port, a second fluid communication port, a second sleeve movable relative to the second fluid communication port, at least one fines mitigation device, and at least one annular isolation device coupled to the liner; (b) activating the annular isolation device so as to provide zonal isolation to a plurality of selected intervals; (c) delivering a fracturing treatment fluid to a first selected interval through the first fluid communication port; (d) actuating a shifting tool so as to move the first sleeve into a position whereby fluid flow through the first fluid communication port is terminated; (e) delivering a fracturing treatment fluid to a second selected interval through the second fluid communication port; (f) actuating the shifting tool so as to move the second sleeve into a position whereby fluid flow through the second fluid communication port is terminated; wherein steps (d) through (f) are performed without removing the shifting tool from the wellbore; and (g) establishing fluid communication between at least one of the selected intervals and the liner through the at least one fines mitigation device.
