A construction of detailed seismological models is based on combined seismic interpretation of effective acoustic impedances (AI), effective reflectivity (RC) sections, cubes and well logging data. The construction is executed for the purpose of finding in these models the potential oil-bearing objects (hydrocarbon prospects), buried paleo-riverbeds, oil-water contacts (OWC), reefs, stratigraphic unconformities, strata wedging and others.
The seismogeological model of the real medium, combined with fragments from AI and RC sections and with vertical sections of analyzed wells, shows the most informative ratio of structural elements and forms of the studied sediments, the relatively thin structural and lithological, and combined oil and gas traps.
In some cases, these models fix replacement areas and wedging of productive horizons, organogenic structures, and stratigraphic unconformity. In the presence of relevant information (seismic, dynamically expressed) the oil-water (OWC) and the gas-water (GWC) contacts between fluids are fixed as well.
