Integrated Approach to the Analysis of Achimov Deposits for the Purpose of Optimizing Drilling

This paper presents the results of an integrated approach to the analysis of the geological structure and the subsequent of the productive Achimov deposits development: deposits X and Y located in Western Siberia. The main difficulties in the development of the Achimov deposits are associated with a high heterogeneity, a low degree of prediction of effective thicknesses, the difficulty of correctly calculating well flow rates, saturation behavior and, accordingly, water cut, and high production decline rates identified as a result of putting new wells into operation.
