## Abstract

Systems for modeling and building models of oil and gas deposits. In particular, the utility model relates to systems designed for automated identification of surfaces for building a geologic-hydrodynamic model of an oil and gas deposit based on seismic data. A technical result is the improvement of the accuracy in building a geological-hydrodynamic model of an oil-and-gas deposit. The objective of this utility model is to provide a system designed for building a geological-hydrodynamic model, in particular, automated (that is, requiring the user to participate only in the stage of initial data input) construction of a set of surfaces based on input seismic data. The output surfaces can be used, without additional processing, to construct a geological-hydrodynamic grid. The input data for the system are volumes of seismic data attributes P, Q; and seismic volume (optional).
