         2 . The completion assembly of  claim 1 , wherein the plurality of detectable references include radioactive elements. 
     
     
         3 . The completion assembly of  claim 1 , wherein the plurality of detectable references are PIP tags. 
     
     
         4 . The completion assembly of  claim 1 , wherein the plurality of detectable references are cobalt wire inserted between threaded connections of the outer tubing string. 
     
     
         5 . The completion assembly of  claim 1 , further comprising one or more detectable references located in the cased section of the wellbore. 
     
     
         6 . The completion assembly of  claim 1 , wherein the plurality of detectable references are located at every stand along a length of the outer tubing string. 
     
     
         7 . The completion assembly of  claim 1 , further comprising a setting packer that includes slip assemblies and seals for providing a seal and gripping relationship between the outer tubing string and the cased section of the wellbore. 
     
     
         8 . The completion assembly of  claim 1 , further comprising one or more shrouded or non-shrouded closing sleeves positioned proximate to the one or more screen assemblies. 
     
     
         9 . The completion assembly of  claim 8 , where the one or more shrouded closing sleeves each comprise:
 a shroud disposed concentrically about the outer surface of the outer tubing string;   one or more fracturing ports disposed through the outer tubing string, thereby providing a passageway for treatment fluid to therethrough; and   a sleeve slidably positioned between the outer tubing string and the inner tubing string such that it may be actuated to move relative to fracturing ports for opening and closing the passageway provided by fracturing ports.   
     
     
         10 . The completion assembly of  claim 1 , further comprising an inner tubing string having an inner central passageway for flowing a treatment fluid, wherein the inner tubing string extends within the outer tubing string and an annulus is formed therebetween. 
     
     
         11 . The completion assembly of  claim 1 , further comprising a pipe tally reference of the completion assembly within the wellbore. 
     
     
         12 . A method for multiple zone fracturing, packing and well treatment of an open hole section of a wellbore having casing positioned above the open hole section, the wellbore having a plurality of production zones, the method comprising:
 (a) placing into an open hole section of the wellbore an outer tubing string having an upper end adapted for connection with a lower end of a cased section of the wellbore, each portion of the outer tubing string being positioned adjacent one or a plurality of production intervals; and   (b) registering a location of the outer tubing string with reference to the wellbore by a method being selected from one or both of the following: (i) a pipe tally reference, or (ii) a plurality of detectable references located along a length of the outer tubing string.   
     
     
         13 . The method of  claim 12 , further comprising registering the location of the outer tubing string with reference to the wellbore with a logging tool reference to a detectable reference in the cased section of the wellbore. 
     
     
         14 . The method of  claim 12 , further comprising disposing radioactive traceant within a proppant deposited or packed between the outer tubing string and surrounding formation. 
     
     
         15 . The method of  claim 12 , wherein the plurality of detectable references are radioactive. 
     
     
         16 . The method of  claim 12 , further comprising inserting cobalt wire between threaded connections of the outer tubing string. 
     
     
         17 . The method of  claim 12 , further comprising correlating a position of the outer tubing string in relation to one or more radioactive PIP tags in the casing with a no-go sub or a radioactive mark sub disposed in the outer tubing string. 
     
     
         18 . An open-hole multiple zone fracturing, gravel packing and treatment completion assembly for single trip fracturing and packing operations of an open hole section of vertical, horizontal, or deviated wellbore having a plurality of production intervals, the completion assembly comprising:
