Quantifying the partial penetration skin factor for evaluating the completion efficiency of vertical oil wells

Abstract An oil well's productivity is generally considered the standard measure of performance. However, depends on several factors, including fluid characteristics, formation damage, reservoir's formation, and kind completion well undergoes. How a partial can affect performance will be investigated in detail this study, as nearly every vertical only partially completed result gas cap or water coning issues. Partially penetrated wells typically experience larger pressure drop flow caused by restricted regions, thus increasing skin factor. A major challenge for engineers when developing designs optimizing factor variables devising testing suitable penetration comparing options. Several researchers have studied calculated factor, but some their results tend to inaccurate cause excessive errors. The present work proposes experimental numerical simulation model accurate estimation pseudo-skin wells. developed simple correlation predicting perforated also compared from available models that are widely accepted industry basis gauging accuracy new estimating Compared other approaches, novel performs providing estimates relatively close those obtained tested models.
