We describe the workflow associated with the construction of a digital twin for a realistic three-dimensional model of a carbonate field in the north of Eastern Siberia. It involves creating the skeleton of the geological object and a set of synthetic seismic data obtained by numerical simulations. To create synthetic data, we carry out finite-difference numerical simulations, which serve as a blind test to verify various techniques used for retrieving a reservoir structure on a subseismic scale. For the simulation of synthetic seismograms, we rely on an original finite-difference scheme based on a local grid refinement in time and space. To cope with the huge amounts of input/output data, we use high-performance computing systems with parallel architecture and a hybrid parallelization strategy for process optimization.
