Title: Method for flowing fluid into or from a well

Abstract: A method for injecting fluid into a well or producing fluid from a well comprising providing one or more single fluid line sliding sleeve downhole tool assemblies into a well in a closed position, applying a first pressure from a fluid source simultaneously to open at least one of the single fluid line sliding sleeve downhole tool assemblies, and allowing fluid to move into tubing or into a reservoir. The method contemplates the use of multiple single fluid line sliding sleeve downhole tool assemblies, wherein the first pressure causes only one of the tool assemblies, or one operably connected plurality of tool assemblies, to be in an open position at any time.
