System for automated identification of surfaces for building of geologic hydrodynamic model of oil and gas deposit by seismic data

A computerized system for automated identification of surfaces for building a geologic-hydrodynamic model of an oil-and-gas deposit based on seismic data, comprising:

• a data identification module;
• a surface-continuation module which is linked to the data identification module and comprises the following modules connected in series:
• a module for determination of surfaces, whose input is the input of the surface-continuation module;
• a domain determination module;
• a grid node adding module;
• a module for setting parameters of seismic attribute volumes;
• a module for setting coordinates of the newly added node;
• a module for determining coordinates of the adjacent node;
• and a module for setting a surface depth parameter in this node, whose exit is the exit of the surface-continuation module;
• a surface-sorting module which is linked with the surface-continuation module and comprising the following modules connected in series:
• a module of ordering the depths of surfaces, whose input is the input of the surface-sorting module, and a module for setting depths of surfaces, whose exit is the exit of the surface-sorting module;
• a clarification module which is linked with the surface-sorting module of sorting and which comprising the following modules connected in series:
• a module for determining the surfaces to be processed, whose input is the input of the clarification module;
• a module for determining functionals and gradients of surfaces to be processed;
• a module for determining the displacement distance;
• a module for determining the attainment of the minimal value of the functional;
• a displacement module;
• a memory module;
• an exclusion module;
• a module for determining processed surfaces, the latter module having one exit connected with the input of the surface-sorting and another exit connected with the input of the module for determining the current grid pitch, which has one exit connected with the input of the module for determining surfaces to be processed and another exit connected with the input of the module for iteration and determining of the attained size, the module for iteration and determination of the attained size being connected with the data identification module and being provided with a possibility of enabling iterative implementation of the functions of the data identification module, the surface-continuation module, the surface-sorting module, the clarification module, the module of determining the current grid pitch, and the module for iteration and determination of the attained size until a model with parameters identified by the data identification module is obtained.
