Abstract:
Zone isolation is a leading concern for operators that wish to fluidly treat a well. By utilizing a ported sliding sleeve assembly that is highly resistant to leaking after being opened and closed through multiple cycles a wellbore may be accessed at any ported sliding sleeve assembly location without plugging the wellbore below the ported sliding sleeve assembly and will allow any ported sliding sleeve assembly to be accessed in any order.
