Carbon Capture & Storage and the selection of potential sites is increasingly important. Geoex MCG has developed a study aiming to characterize the subsurface and evaluate the suitability for carbon capture sites in Texas Federal waters using ML techniques. 8 x 3D’s and 3 x 2D’s from the seismic data available at the BOEM were studied, covering an area of approximately 31,197 km2 from ‘High Island’ to ‘Brazos’ protraction areas. Due to the size of the AOI, ML delivered a better understanding of the subsurface framework more efficiently than standard workflows. Seismic data quality varied considerably depending on vintage (1984-1990). Before ML workflows could be applied, a conditioning workflow was applied to ensure a more consistent database. With a view to gaining a better AOI regional understanding, Earth Science Analytics’ EarthNet AI software was used to generate fault, horizon and 1D well predictions across all 3D seismic volumes and within the critical window for CO2 injection, using a semi-supervised learning approach. These interpretations were extrapolated to the 2D data on areas not covered by 3D. This approach, combined with more detailed mapping, ensured that ‘prospect level’ sites could be ranked based on suitability for CO2 injection. Additional risking studies focused on the pressure environment and potential sealing capacity. With a view to comparing various investment scenarios, volumetric capacity and preliminary economic screenings were applied to optimal areas that demonstrated viability and the lowest risk of failure.
