| Summary: | Hydrocarbon prediction from seismic amplitude and AVO is a daunting task.
Many AVO attributes were presented for this purpose. However, amplitude/AVO
interpretation is ambiguous due to effects of lithology and pore fluid. To reduce this
ambiguity, this study presents a new AVO attribute called "J" based on Gassmann-
Biot fluid substitution.
J attribute is defined as a rotation from Jp and Js which are two parameters we
defined in this study. The rotation angle is derived from brine response. Thus, J
attribute can distinguish hydrocarbon from brine. |
