Forecasting the distribution zones of the accretionary complex of meandering rivers in the section of the PK1 formation of the Kharampu deposit

K.B. Kuziv, A.A. Alexandrov


The Cenomanian deposits of the north of the West Siberian Plate are important targets for the gas industry, and effective development in these deposits requires preliminary analysis and identification of potential risks. The accumulated experience in the development of the deposits under consideration has determined that the greatest danger for the development of the deposit at the first stages is the early abandonment of wells caused by uneven, local rise of the gas-water contact (GWC), associated with lithological heterogeneity and the presence of gas-water "merge windows" in the contact zone.
The article presents the results of studies, including the collection and analysis of data on the geological structure of the PK1 object of the Kharampur field, the lithological properties of the formation, and the facies characteristics of the section of the productive formation. Methods of forecasting and modeling are applied, which determine the risk zones for the appearance of confluence windows in the accretionary complexes of meandering rivers.
The results obtained can be used in the decision-making process when designing wells, and taking them into account will reduce the risks of early retirement of wells associated with the development of the accretionary complex of rivers.
