Abstract

This paper presents a comprehensive methodology for identifying and integrating facies barriers into geological and hydrodynamic models of the Jurassic formations in Western Siberia. Conventional approaches overlook silicate‑filled channels, leading to errors in structural mapping and drilling failures. A five‑stage approach has been implemented, combining seismofacies analysis, GIS data, GDIS results, and machine‑learning techniques based on Kohonen maps. The constructed probability cube of the collector and the discrete regional cube allowed for the incorporation of facies barriers, justification of blocks with varying VNK and reservoir pressure, and improved the accuracy of hydrodynamic model adaptation by 10 %. Practical application of the method prevented drilling into non‑collector zones, increased the production rate of new wells by 3.5‑fold, and confirmed the feasibility of scaling the approach.

Key words:

facies barriers, seismic facies analysis and wavefield spectral decomposition, machine learning, IP-Seismic, differential compaction, reservoir simulation (hydrodynamic modeling), Western Siberia, Jurassic deposits, bottomhole pressure gauges and well testing, water-oil contact (WOC) and hydrodynamic regions
