The brittleness index has a diverse range from 5-35%, with significant contrast at shallow zones. The brittleness index of the subsurface layers was estimated, which is a critical rock property that provides information about rock hardness and fragility phenomenon. Well-tie analysis was used for inversion of 3D seismic data to extract detailed waveform and amplitude information. Seismic data-derived geomechanical properties were compared with the mechanical earth models for the first time for this field. 3D Mechanical Earth Models (MEM) were also developed using the well logs, seismic horizons, and drilling data. The Poison's ratio (PR), Young Modulus (YM), and elastic moduli for a reservoir block were estimated using 3D seismic pre-stack data and well data. Deriving and understanding geomechanical properties is crucial for reservoir management as it can avoid drilling and production-related problems that cause environmental impacts associated with land subsidence and uplift. ![]() Seismic data provide evidence about hydrocarbon deposition, geological and geophysical subsurface information, including geomechanical aspects.
