Modeling of Permian stream-bed deposits in the Izhma-Pechora syneclise and the Upper Pechora depression conjunction zone

Abstract

In the Izhma-Pechora syneclise, several fields have been discovered that are limited to sand deposits deposits of stream-bed genesis. However, it is difficult to find lithological traps using seismic data due to the complex nature of the distribution of sandy deposits and many discontinuous faults in the Permian terrigenous section. The article attempts to model the continental depositional environment that existed in the Izhma-Pechora syneclise and the Upper Pechora depression conjunction zone during the Ufimsky, Kazansky and Tatar ages of the Permian period. It aims to reconstruct the history of the development of the area and to trace the distribution of alluvial and lacustrine-alluvial sand deposits. DionisosFlow's unique industrial package helps to create a 3-dimensional model of the development of the area, to simulate the process of sedimentation of the target area, and to construct predictive maps of sandstone, siltstone and clay spread. The western part of the modeled area demonstrates the existence of slightly wandering north-easterly directed beds and their small offshoots. The south-eastern part of the area, dated to the Ufimsky age, shows deltaic deposits. The method of predicting the distribution of channel deposits based on sedimentological modeling is supposed to be used for territories uninvestigated by 3D survey. The aim is to locate the source of the reservoir and plan the seismic survey.
