Subsalt Seismic Inversion Data from 50 Blocks in the Gulf of Mexico

A case study using 481.25 square miles of poststack, wide-azimuth seismic data from 50 Outer Continental Shelf blocks in the Green Canyon area of the Gulf of Mexico. The dataset, authored by Huyen Bui of Schlumberger, incorporates four subsalt wells and four interpreted horizons for a poststack inversion method to predict reservoir properties in Miocene and Wilcox formations. Results were validated with a blind test well.

Use Cases

• Predicting sand/shale distribution based on the described incorporation of geology and rock physics.
• Validating seismic inversion robustness for subsalt areas based on the described blind test.
• Generating low-frequency models for acoustic impedance based on the described method using well velocities, seismic velocity, and interpreted horizons.
• Assessing reservoir properties in Miocene and Wilcox formations based on the described target reservoirs.

Strengths

• Covers 481.25 square miles of seismic data from 50 distinct blocks.
• Incorporates four subsalt wells and four interpreted seismic horizons for validation.
• Includes a blind test well to demonstrate method robustness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Gulf of Mexico study area.
