Measuring the geotherm with gas hydrate bottom-simulating reflectors: a novel approach using three-dimensional seismic data from the eastern Black Sea
Measuring the geotherm with gas hydrate bottom-simulating reflectors: a novel approach using three-dimensional seismic data from the eastern Black Sea
Gas hydrate-related bottom-simulating reflectors mark the phase boundary between hydrate and free gas in the subsurface, and therefore may be used to estimate geothermal gradients and hence heat flow. The depth and temperature of the phase boundary depend on the composition of the hydrate-forming gas and of the pore fluid. In the absence of direct sampling, these compositions remain unknown. We develop an alternative approach that is less sensitive to compositional uncertainties and can be applied when the bottom-simulating reflector is densely sampled in a region with significant seabed relief. We apply this approach to a three-dimensional seismic dataset from the eastern Black Sea

Abstract
Gas hydrate-related bottom-simulating reflectors mark the phase boundary between hydrate and free gas in the subsurface, and therefore may be used to estimate geothermal gradients and hence heat flow. The depth and temperature of the phase boundary depend on the composition of the hydrate-forming gas and of the pore fluid. In the absence of direct sampling, these compositions remain unknown. We develop an alternative approach that is less sensitive to compositional uncertainties and can be applied when the bottom-simulating reflector is densely sampled in a region with significant seabed relief. We apply this approach to a three-dimensional seismic dataset from the eastern Black Sea
