METHODS FOR REGULATING FLOW IN MULTI-ZONE INTERVALS

摘要

Methods of regulating flow in a hydrocarbon well include identifying at least two dissimilar zones in an interval of a well, perforating a well completion in the interval according to a limited-entry perforation strategy, and re-perforating the well completion in the interval according to a re-perforating strategy. The limited-entry perforation strategy is adapted to produce a plurality of limited-entry perforations. The limited-entry perforation strategy varies the perforations within the interval based at least in part on dissimilarities between the at least two dissimilar zones. The re-perforation strategy produces a plurality of re-perforations and is based at least in part on the limited-entry perforation strategy. The re-perforation strategy is adapted to at least substantially align a portion of the re-perforations with a portion of the limited-entry perforations.
