Patent ID: 8899339

Claim:
A zonal isolation system for use in a wellbore, the zonal isolation system comprising: a tubular segment having an opening defined therein and comprising a first end and a second end; a first isolation assembly adapted to connect to the first end of the tubular segment and adapted to include an outer diameter portion having at least one restriction member selected to have an outer diameter between about 90% and about 110% of a drift diameter of the wellbore to block at least a portion of a wellbore annulus between the tubular segment and a wellbore wall when in a wellbore, and wherein the isolation assembly comprises (i) a coupling tubular adapted to be coupled to one or more tubular segments, and (ii) at least one restriction member in sliding association with the coupling tubular for movement along a length of the coupling tubular; and a second isolation assembly adapted to connect to the second end of the tubular segment and adapted to include an outer diameter portion having at least one restriction member selected to have an outer diameter between about 90% and about 110% of the drift diameter of the wellbore to block at least a portion of the wellbore annulus between the tubular segment and the wellbore wall when in the wellbore; wherein at least one of the first isolation assembly and the second isolation assembly does not include a wellbore sealing member and the at least one of the first isolation assembly and the second isolation assembly cooperates with the opening to form an isolation zone having at least two outlets including a first outlet through the opening and a second outlet past an outermost surface of the outer diameter portion of the restriction member of at least one of the first and second isolation assembly; wherein the isolation zone is configured to have hydraulics during operation driving at least a majority by volume of the fluids through the first outlet and at least substantially restricting but not preventing fluid from passing the outer circular surface of the isolation assembly, and wherein the tubular segment is completely above or below the isolation assembly.
