Completion scenarios and knowledge of formation damage distribution are key factors that determine the success of horizontal well applications. In a bottom water drive reservoir the completion scenario should be selective because a significant portion of the horizontal well section would not be productive at late production period. A simple correlation to estimate pseudoskin factors due to partial completion for a horizontal well is provided. When water or gas coning is not expected, distributed perforation intervals in a damaged formation yield the highest productivity.
