Building Seismically Guided Integrated Hydrodinamic and Geomechanic Model Based on the Effective Model of the Medium

Using seismic data to estimate reservoir properties and parameters of the stress-strain state of the environment in the inter-well space can significantly improve the quality of the complex hydrodynamic and geomechanical model as a basis for oil field development planning, drilling risk assessment and complications during drilling and completion of the reservoir.

Effective model of the rock based on Theory of Effective Medium, is the basis for a correct upscaling of dependencies between the static elastic properties measured on core samples and dynamic properties received from sonic and and seismic attribute analysis. This technique allows to take into account non-linear behavior of the dependencies, obtained during core laboratory tests on ultrasonic frequency range and provide smart upscaling tool for reservoir properties propagation with logging and seismic data. Various aspects of building integrated seismically guided 3D static, dynamic and geomechanical model and are discussed and illustarated on the model of one of the parts of clastic oil reservoir. Comparison made between conventional hydrodynamic and coupled modeling for depletion drive scenario.
