Patent ID: 7934555

Claim:
A method of subterranean completion, comprising: locating a production screen adjacent each of at least two spaced apart producing zones with said production screens connected with a connecting tubular extending between them and said connecting tubular extending through a non-producing zone to define an annulus that spans said zones; providing in said connecting tubular at least one screened opening; depositing gravel in said annulus adjacent said non-producing zone while taking fluid returns through said screened opening; connecting a production string comprising external spaced barriers to straddle said production screens; isolating said screened opening while said screened opening is open between said spaced barriers while producing through an opening in said production string that is located outside the portion of said production string between said spaced barriers, said opening aligned with at least one said production screen; using only said deposited gravel to control flow between said producing zones through said annulus while one of said producing zones is producing through its associated production screen and into said production string.
