A2. Processing/Inversion: Anisotropy, AVO and Seismic Inversion, Full-Waveform Inversion (FWI), Q-Migration etc.

Conveners: Can ÖREN, Fuchun GAO, Taner ARPACI

Topic Description:

AVO, and Seismic Inversion: Reservoir Geophysics and quantitative interpretation methods, including deterministic and stochastic approaches, have been widely used in academic and industrial studies to infer elastic and petrophysical properties of subsurface reservoirs. Rock physics and modeling, AVO (amplitude-versus-offset) modeling and analysis, pre-stack and post-stack inversion methods and neural network applications are the main techniques used in these studies. Reservoir geophysics methods are not utilized only for the detection of fluids in the reservoir zones but also for creating a link between geology and geophysics. Therefore, diverse scaled data sets such as outcrops, thin sections and cores, well logs and seismic data are used to explain the relation between these disciplines. Due to uniqueness of solutions in each workflow itself, these methods have been still developing. We invite contributions related to oil and gas exploration and development, 4D feasibility studies, CCUS (carbon capture, utilization and storage) and more. Contributions on technical developments and case studies are highly welcome.

Full-Waveform Inversion (FWI), Q-Migration, etc.: Retrieving detailed subsurface physical parameters is crucial in exploration geophysics. Full-Waveform Inversion (FWI) has gained significant attention for its ability to produce high-resolution velocity, anisotropy, attenuation (Q), and elastic models. Advances in stable objective functions and accurate physics, including anisotropic elastic wave propagation, have made FWI effective, especially in complex geological settings. FWI not only delivers standalone high-resolution images but also enhances advanced seismic migration techniques such as Q-migration and least-squares migration, offering robust AVO-friendly imaging critical for reservoir characterization. Historically challenged by computational demands and cycle-skipping issues, FWI has overcome many barriers due to improved hardware, low-frequency sources, and better objective functions, with elastic FWI becoming increasingly popular. Current challenges include multi-parameter inversion, multi-component datasets, and uncertainty quantification.

Reverse Time Migration (RTM), a full-wave-equation-based method, excels in imaging complex structures with high amplitude fidelity, particularly when combined with least-squares approaches. While acoustic RTM is widely used, elastic and attenuation-compensated (Q) RTM are gaining industrial relevance.

This session welcomes contributions on theoretical and practical advancements in acoustic/elastic FWI, least-squares Q migration imaging and multi-parameter inversion across diverse geological scenarios to improve our understanding of the earth's interior.

Anisotropy: Topics such as anisotropic velocity model building and migration, the impact of anisotropy on NMO and AVO, the importance of azimuthal data, the use of well and VSP data for calibration, and elastic and azimuthal inversion for fracture prediction are welcome in this session.

Collaborative approaches that merge geological mapping, structural interpretation, geochemical data, and petrophysical analysis with advanced geophysical techniques provide deeper insights into subsurface systems and significantly reduce exploration risk.

In mineral exploration, especially for critical and strategic resources like lithium and rare earth elements, combining geophysical data (gravity, magnetics, EM, IP) with geological models improves the targeting of ore bodies and alteration zones. For hydrocarbons, integrating seismic data with structural and stratigraphic interpretation enhances reservoir prediction and reduces drilling uncertainties. In geothermal exploration, joint studies support the identification of heat sources, fluid pathways, and reservoir boundaries through the integration of resistivity, MT, gravity, and geological data.
