The AVO Response of a Pennsylvanian Age Channel Sandstone in the Arkoma Basin, Oklahoma [Abstract]
A seismic line imaging a gas-producing channel sand in the Pennsylvanian Hartshorne Formation was acquired in September 1994. The dataset was processed to retain relative amplitude fidelity and has been analyzed for anomalous amplitude behavior. Frequency domain filtering and CMP mixing were applied to improve the signal/noise ratio of the data. Despite this improvement, visual inspection of amplitude variations on trace gathers was not possible. Statistical determination of several amplitude attributes, however, provided an alternative procedure for interpretation of amplitudes. Attribute plots show that the channel sand does, indeed, have a distinctive AVO response. This signature is a positive normal incidence reflection of moderate relative amplitude which displays a strong increase in amplitude with offset.
