Abstract

Many oil fields having distinctive reserves with the production operations are associated with the difficulties and problems. These difficulties is related to many features and these increased when the well is operated at bottomhole pressure equivalent to the bubble point pressure. Therefore, the objective of this research is to avoid and marmite the problem in the investment process. The data has been collected from different fields in Russia. For verification of the efficiency of developed methods data, were collected from Novi Oringoe fields, where the plunger lift has been used as production method. This study has focused on these fields because of analogy of the production factor with Yemeni fields in Sabatain basin. Therefore, the developed methods results obtained in this research can be applied to Yemeni oil fields.
Results obtained in research showed a good agreement between actual and calculated values of minimum bottomhole pressure. This leads to selecting the appropriate method of artificial lift according to permissible factors.
