Characterizing Subsurface Structures for Geologic Carbon Storage at Iron Mountain in Utah
Description:
Subsurface structure imaging and fault detection are crucial for site characterization and risk assessment of geologic carbon storage. We use 2D surface seismic data acquired at Iron Mountain, Utah, USA to characterize subsurface structures. These seismic data were acquired using vibroseis sources along three 2D walkaway lines at the surface of the survey area. The source spacing of each survey line is about 91 m and the receiver spacing is about 45 m. The lengths of the seismic lines are around 9 km. We build 2D velocity models along three seismic survey lines using first-arrival traveltime tomography and prestack depth migration velocity analysis. We then use prestack depth migration to produce high-resolution images of subsurface structures. Finally, we employ a machine learning algorithm to delineate faults on the migration images. Our results provide valuable information for studying the feasibility of geologic carbon storage at Iron Mountain in Utah.
