Seismic velocity structure at a gas hydrate reflector, offshore western Colombia, from full waveform inversion
TA Minshull, SC Singh… - Journal of Geophysical …, 1994 - Wiley Online Library
Seismic reflection profiles across many continental margins have imaged bottom simulating
reflectors (BSRs), which have been interpreted as being formed at the base of a methane
hydrate stability field. Such reflectors might arise either from an impedance contrast between
high‐velocity, partially hydrated sediments and water‐saturated sediments or from a contrast
with partially gas‐saturated sediments. These alternatives may be hard to distinguish by
conventional amplitude‐versus‐offset or waveform modeling approaches. Here we …
