摘要： A method of providing zonal isolation in a wellbore completion includes the steps of identifying an anticipated zone for isolation in a wellbore before completing the wellbore; selecting, before completing the wellbore, a completion assembly and a cooperative deployable isolation assembly to isolate the anticipated zone; completing the wellbore with the selected completion assembly; and connecting the selected deployable isolation assembly in the selected completion assembly to isolate the anticipated zone.
