Seismic analysis of the Sooner field

摘要

An attribute and spectral decomposition analysis led to better understanding of valley fill features. Advanced Secondary Recovery Project for the Sooner 'D' Sand Unit, Weld County Colorado Final Report by diversified Operating Corporation, November 1996" stated that the Sooner Unit has been interpreted to be a Cretaceous D Sand stratigraphic play, located in Weld County in northeastern Colorado. The reservoir is interpreted to be funnel-mouth estuary and valley fill. By correlating log data, the D Sand reservoir appears to be a series of vertically stacked channels with a maximum gross thickness of 70 ft (21 m). Commonly, the channels have a gross thickness of 30 ft (9 m) or less. The D Sand individual sands and valley fills have been very difficult to visualize using conventional amplitude data. The following workflow will employ a variety of seismic attributes, among them spectral decomposition (SD), to resolve this visualization problem.
