A method for installing a tubular string in a wellbore, the method comprising: providing a tubular including a wall with a port extending therethrough, and a cement diffuser installed over the port and carried along with the tubular, the cement diffuser including a collection of fibers secured over the port on at least the outer diameter of the tubular; running the tubular into the wellbore and thereby creating an annulus between the tubular and the wellbore wall; pumping cement into the annulus; allowing the cement to set in the annulus, the cement diffuser creating a weak point in the cement in the annulus radially adjacent the port; and, after allowing the cement to set, injecting fluid from the tubular through the port and into the annulus to fracture the wellbore.
