Description
With a shallow anhydrite layer, strong multiples and converted wave contamination, Southern Oman represents a technical challenge for land velocity model building and imaging. While acoustic land full-waveform inversion (FWI) has proved successful on new broadband datasets in Northern Oman, no successful application has been reported for Southern Oman. We show here that the challenge of acoustic FWI in South Oman can be overcome using a dedicated workflow combining Multi-Wave Inversion (MWI) and multi-Dimensional Optimal Transport FWI (multiD OT-FWI). The key component of the workflow is the very near surface characterization provided by surface wave dispersion curves, which allows delineation of the Rus layer in the initial FWI model. MultiD OT-FWI is then used to mitigate amplitude issues in the presence of short period multiples and reduce cycle skipping beyond the depth of penetration of diving waves.
About the Lecturer
Lindsey Smith is a geophysicist with 19 years of experience at bp, where she has contributed to a wide range of North Sea assets and held central roles in both seismic interpretation and analysis. Currently, she is part of the subsurface team for the North Endurance Partnership (CCS) Project. Over the past eight years, Lindsey has developed a strong interest in the role of colour in applied geoscience data visualization. Collaborating with colleagues at bp, she has explored how thoughtful colourmap choices—beyond default settings—can significantly enhance the clarity and effectiveness of data visualization and communication in applied geosciences.
