Abstract

A method of treating a formation includes, running a first string having at least one first port into a completion string having a plurality of second ports, flowing treating fluid through the first string, and flowing treating fluid through the at least one first port and through at least one of the plurality of second ports and into the formation

         2 . The method of treating a formation of  claim 1 , further comprising fluidically aligning a plurality of the at least one first ports with a plurality of the plurality second ports. 
     
     
         3 . The method of treating a formation of  claim 2 , further comprising flowing treating fluid through the plurality of the at least one first ports and through the plurality of second ports aligned with the plurality of the at least one first ports simultaneously. 
     
     
         4 . The method of treating a formation of  claim 2 , further comprising adjusting restriction of the plurality of the at least one first ports prior to running the first string into the completion string. 
     
     
         5 . The method of treating a formation of  claim 2 , further comprising adjusting restriction of the plurality of the at least one first ports according to treating fluid flow rates desired at locations along a borehole where each of the plurality of the at least one first ports will be positioned during treatment. 
     
     
         6 . The method of treating a formation of  claim 5 , further comprising increasing flow restriction of one or more of the plurality of the at least one first ports to be located nearer a heal of the borehole in comparison to one or more of the plurality of the at least one first ports to be located nearer to a toe of the borehole. 
     
     
         7 . The method of treating a formation of  claim 5 , further comprising increasing flow restriction of one or more of the plurality of the at least one first ports to be located nearer a portion of the formation that has high permeability in comparison to one or more of the plurality of the at least one first ports to be located nearer to a portion of the formation that has low permeability. 
     
     
         8 . The method of treating a formation of  claim 1 , further comprising removing the first string from the completion string. 
     
     
         9 . The method of treating a formation of  claim 1 , further comprising producing through the at least one of the plurality of second ports in the completion string and through the at least first port in the first string. 
     
     
         10 . The method of treating a formation of  claim 1 , further comprising sealing portions along the first string to portions along the completion string. 
     
     
         11 . A treatment and completion system, comprising:
 a completion string positioned within a borehole in an earth formation;   a first string runnable within the completion string, having a plurality of first ports distributed along the first string being configured to be in fluidic communication with a plurality of second ports along the completion string, the plurality of first ports being independently settable to a different flow restriction; and   a plurality of seals distributed along the first string or the completion string configured to seal to the other of the first string and the completion string to isolate the plurality of first ports from one another such that treating fluid can be pumped through the first string and through the plurality of first ports and through the plurality of second ports to treat a plurality of zones of a formation simultaneously.   
     
     
         12 . The treatment and completion system of  claim 11 , wherein independent setting of each of the plurality of first ports allows treating fluid flow through each of the plurality of first ports to be customized to match characteristics of the zones that each of the plurality of first ports will be treating. 
     
     
         13 . The treatment and completion system of  claim 12 , wherein the customization adjusts for differences in permeability between the zones. 
     
     
         14 . The treatment and completion system of  claim 12 , wherein the customization adjusts for location along a borehole. 
     
     
         15 . The treatment and completion system of  claim 12 , wherein the first string is runnable to an end of the completion string regardless of how long a highly deviated portion of the borehole is. 
     
     
         16 . The treatment and completion system of  claim 11 , wherein at least one of the plurality of first ports and plurality of second ports include inflow control devices. 
     
     
         17 . The treatment and completion system of  claim 11 , wherein the plurality of first ports are configured to complement the plurality of second ports to create a total desired outward flow restriction through aligned pairs of the plurality of first ports and the plurality of second ports. 
     
     
         18 . The treatment and completion system of  claim 11 , wherein flow restriction through each of the plurality of first ports is adjustable after the first string is run into the completion string. 
     
     
         19 . The treatment and completion system of  claim 18 , wherein adjustment of the plurality of first ports includes fully closing the plurality of first ports. 
     
     
         20 . The treatment and completion system of  claim 18 , wherein adjustment of the plurality of first ports is possible in real time. 
     
     
         21 . The treatment and completion system of  claim 11 , wherein the first string is retrievable from the completion string after injecting a treating fluid and before producing. 
     
     
         22 . The treatment and completion system of  claim 21 , wherein a second string is runnable within the completion string prior to production.
