Gas hydrates: significance in marine site characterization and approach to assessing presence and risk
Sensitivity of seismic amplitude and gas hydrate saturation. From Boswell et al., 2016
 
Have you or your team been asked to comment and assess gas hydrate risk at a deepwater well or field development?  Do you feel that you are addressing the issue but….not really? Do you feel that your team is writing paragraphs about gas hydrates but not quantifying presence or risk?  These questions shaped my early career when I was a young professional and just starting out as a marine geohazards specialist. Persisting with this topic led me to help the US Department of Energy test gas hydrate emplacement theories and seismic targets that were, at the time, unresolved.  Once we were able to make pre-drill predictions and ground truth those predictions, then we could begin to give better, more quantified, advice about gas hydrate risk in our geohazards work.   What I will try to convey in the talk is a data-supported view about how to approach the assessment of gas hydrate risk that can guide you when you start your next project.  

About the Presenter:

Dan McConnell, Global Product Manager - Gas Hydrates & Marine Minerals, Fugro

Dan is the global product manager for gas hydrates and marine minerals for Fugro and a marine geologist with over 20 years of experience with main areas of interest in seafloor mapping and geochemistry surveys, deepwater site characterization, marine mineral exploration, and methane hydrate exploration.  He has authored or co-authored over 45 articles about marine geochemical survey methods, site characterization, and methane hydrate characterization and exploration. Dan participated in the site selection and science party in the landmark Chevron- US Department of Energy gas hydrate drilling expedition in the Gulf of Mexico in 2009. Dan serves on the U.S. Department of Energy Methane Hydrate Advisory Committee. In 2016, Dan was able to go offshore on the MarMine seafloor massive sulfide exploration cruise on the Arctic Mid-Ocean Ridge, and lead the geoscience team on the NORI 2018 Geophysical and Mineral Sampling Survey for polymetallic nodules in the Clarion-Clipperton Fracture Zone.  Dan has a B. A. History and a B. Sc. Geological Sciences from the University of Texas.
