Approaches and Technologies for the Construction of a Reservoir Model Under Conditions of Input Data Uncertainty

The simulated region was characterized by inconsistencies between the drilling data and the results of the structural interpretation of the 3D seismic survey. The absence of signs of amplitude faults in seismic data did not exclude the existence of zones of reduced conductivity in the formation, which significantly affect the wells productivity. The involvement of the regional component was a necessary step in creating a first approximation to the complex tectonic situation in the zone of Bolshekinelsky fault. The study of different-scale geological and geophysical information made it possible to identify the location of large tectonic elements and the features of the development of tectonic elements of a smaller rank. Some of them were implemented in the structural model of the D0-1 formation with the aim of further confirmation during the history matching of field data.

Geological and hydrodynamic models are constructed taking into account the uncertainties in the tectonic structure inherent in this region. Automated calculations using the Big Loop technology were performed, which made it possible to identify the most probable solutions and thereby increase the reliability of the
