A method for fluid-stress modeling of 3D seismic, and drilling data, provided new information on the stress conditions, and on the hydrodynamics of the U11 layer of the Upper Jurassic sandstone reservoir in the Arigol field, Western Siberia, Russia. It is proposed to detect and outline oil fields, and divide them into isolated traps, marked by low sedimentary overburden pressure, and fluid-trapping properties based on correlation between the structural pattern and mapped stress. A different systematic approach was adopted, considering: the use of 3D component seismic data of Vp and Vs velocities; the density ρ, and the stress models of the reservoirs to detect the areas of low overburden pressure P(x, y, z); and the vertical inclination of fractures (faults), j(x, y, z), caused by the non-hydrostatic behavior of stress
