Patent number: 4785196Abstract: Method and apparatus for producing improved synthetic velocity logs from seismic traces. The seismic traces are processed to enhance high frequency content by converting each trace to a spike trace, then filtering the spike trace with a function designed to reduce side lobes and enhance high frequency content. The processed trace is then operated on by a conventional summation process to produce a synthetic velocity log. Due to the enhanced high frequency content of the processed trace, the resulting synthetic log tends to show sharp discontinuities in the geology, much like a log taken from a well.Type: GrantFiled: March 7, 1983Date of Patent: November 15, 1988Assignee: Conoco Inc.Inventor: John T. Reed
