Patent attributes
The present invention provides a method for determining net-sand thickness and net-reservoir volume over a broad range of gross sand thickness in a target zone. A net-resource attribute is designed to estimate net-sand thickness based upon the inner product of the determined probe function and the segment of the seismic trace that includes the target zone. The net-resource attribute and the geographic location for each trace can be stored and a net-resource table may be created. Maps and net-reservoir volume can be generated from the geographical location information and the net-resource attributes. Net-sand thickness allows the determination of the total volume of sand and thus the size of the hydrocarbon container or the net-reservoir volume.
