Specific Features of the Geological Structure of the Formations YUS₁¹ and YUS₁² of the Sredne-Ugutskoye Oil Field and their Influence on the Effectiveness of Pay Zones Completion

Abstract:

The choice of the most effective technology for reservoir completion depends mainly on the conditions for the formation of its constituent deposits and the specific features of their geological structure. This circumstance makes it possible to predict the productivity of newly drilled wells, transferred to the pay zone, as well as to plan the necessary geological and technical interventions with maximum efficiency. The research objective is to assess the influence of specific features of the geological structure of the production zone on the effectiveness of pay zones completion. Facies maps for productive formations were constructed with the help of paleogeographic and facies methods of analysis; a detailed geological and routine analysis made it possible to numerically assess the tightness of the connection between the development indices and the geological and geophysical characteristics of the objects under investigation.
