Methane Hydrate Systems

 

High resolution data

Thinly bedded hydrate layers require high frequency, high resolution seismic systems for proper imaging and analyses. My current work focuses on the Green Canyon in the Gulf of Mexico to examine hydrate concentrations and provide estimates of in place methane resources.

Evidence of the unexpected

Joint methods leveraging high resolution data and cutting edge inversion techniques provide evidence for free gas inclusion within the hydrate stability zone. Recent modeling work suggests agrees with our observations for thinly interbedded, porous, hydrate rich sediments with less porous media.

Inversion results

Full waveform inversion results confirm in situ drilling results where hydrate layers are thin, and interbedded with finer grained sediment layers. Prestack waveform inversion results are marked improvements over traditional seismic data processing.
