Automatic Leak Detection in Carbon Sequestration Projects
(2020-05-15)The international commitments for carbon capture will require a rapid increase in carbon capture and storage (CCS) projects. The key to any successful carbon sequestration project lies in the long term storage and ... -
Examining Seismic Amplitude Responses of Gaseous Media Using Unsupervised Machine Learning
(2020-12-18)The presence of gas in the rock’s or sediment’s pore space significantly affects its seismic amplitude response and modifies its subsurface signature. Gas hydrates in the subsurface are often difficult to image with ... -
High Resolution Geophysical Imaging Reveals Major Faults in the Southern Oklahoma Aulacogen: Implications for Mid-Continent Seismic Hazards
(2019-07)While intraplate seismicity can occur anywhere, events frequently localize along preexisting buried basement faults associated with ancient tectonic features and boundaries (ATFBs). Detailed structural study of these ... -
A PALEOMAGNETIC AND PETROGRAPHIC ANALYSIS OF UNCONFORMITY SURFACES IN NEVADA AND MISSOURI: POSSIBLE IMPLICATIONS FOR PALEOWEATHERING PROCESSES
(2017-08)Paleomagnetic dating has proven to be a valuable tool in dating geologically significant events such as timing of deposition, deformation, or diagenesis. When combined with petrographic methods and field relationships, we ... -
Passive Processing of Active Nodal Seismic Data: Estimation of Vp∕Vs Ratios to Characterize Structure and Hydrology of an Alpine Valley Infill
(2019-08-15)The advent of cable-free nodal arrays for conventional seismic reflection and refraction experiments is changing the acquisition style for active-source surveys. Instead of triggering short recording windows for each shot, ...
