Presented by Sergey Shevchenko. This presentation demonstrates how the Extended Elastic Impedance (EEI) concept has been used as a method for reservoir monitoring, calculating changes in pressure and saturation in a producing reservoir by applying EEI to time-lapse seismic data. The method uses time-lapse seismic difference data rotated to specific EEI χ angles which are optimised for the changes expected in a given reservoir.

Presented by Jeff Goodall, HyTerra. This presentation demonstrates how the targeted methodology for natural hydrogen exploration has moved from surface circular features to a more expansive subsurface geological model which supports hydrogen generation on a regional scale in localized prospective areas.
The deliberate targeting of natural hydrogen resources in the Central Midwest of the USA is underway with a rapid ramp-up of exploration activity, including drilling and well testing by multiple companies. These data will help inform and refine our understanding of natural hydrogen system/s both in the Central Midwest and in other prospective locations globally.
