Regularities in the development of fracturing zones in rocks of the sedimentary cover of Western Siberia, based on the results of the application of the OilRiver technology, horizontal well logging and hydrofracturing data

Abstract

The article presents known results of theoretical and experimental works, describing the regularities of the formation of fractured-block structures in platform areas. The above examples of mapping such structures in Western Siberia on the basis of the use of the OilRiver technology fully correspond to these patterns. Target drilling of the mapped fractured zones by horizontal wells indicates a mapping accuracy of 30-50 meters. According to the logging, the zones of fracturing in the Jurassic and Cretaceous rocks are confined to the zones of carbonatization, and in connection with this, when the formation is fractured 2.3 times more it is likely to get «STOP». The accuracy and completeness of the fractured zones mapping using the OilRiver technology opens up the possibility of using filtration channels to improve the profitability of oil production.
