Abstract: Methods of treating a portion of a wellbore include introducing a first treatment fluid to a far-field area of a subterranean formation, the first treatment fluid comprising a first proppant, and introducing a second treatment fluid to a near wellbore area of the subterranean formation, the second treatment fluid comprising a second proppant different from the first proppant. The method includes reducing flowback of the first proppant into the wellbore while permitting liquid passage into the wellbore by forming a near wellbore barrier containing the second proppant.
