Description:
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 hydrateforming
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.
