Title

Performance of Perforated Completions in the Presence of Anisotropy Laminations or Natural Fractures

Abstract

Finite-element method (FEM) was used to evaluate the steady-state flow response of the near-wellbore region in the presence of anisotropy, shale laminations, and natural fractures. The relative importance of various geometric perforation parameters under such conditions was also examined. The study indicated that completion efficiency is strongly influenced by common heterogeneities. The variation in productivity is substantial and emphasizes the importance of including a good description of the formation heterogeneities in the design and evaluation of a perforating program. The best description is derived by use of data from all available sources (cores, well tests, and logs). The principal findings of this study are discussed.
