ABSTRACT:
A method of completing a wellbore includes the steps of connecting an isolation tool to a conveyance, the isolation tool including a tubular base member having an internal bore and an outer housing forming a first chamber and a second chamber separated by a wall; the first chamber having a first inlet port in communication with the internal bore and a first outlet port formed through the housing; the second chamber having first inlet port in communication with the internal bore and a second outlet port formed through the housing; a first material disposed in the first chamber; and a second material disposed in the second chamber; running the conveyance into the wellbore, an annulus formed between the isolation tool and sidewall of the wellbore; and activating the isolation tool to form a barrier to fluid flow in the annulus.
