A methodology for selection the most optimal well operation method in oil rims

To date, the reserves of fields with oil rims are significant and belong to the category of hard-to-recover. Not only domestic companies, but also foreign companies, such as Shell, Repsol and Schlumberger, are interested in developing these fields. A particularly important stage in the development of fields with oil rims is the selection the well operation method. Mistakes in choosing the extraction method can lead to losses of the project's NPV and the impossibility of further development of the field. This article provides a comparative analysis of methods for evaluating the method of well operation, and identifies their key advantages and disadvantages. We also describe our own methodology for selecting a method for operating wells in oil-rim conditions. The technological and economic efficiency of the proposed method, tested at one of the field of company LUKOIL-Komi LLC with oil rim, is proved. The developed method is compared with other methods for evaluating production methods.
