Raymond A Ergas: Method of editing seismic traces, as say gathered by large multichannel collection systems. Chevron Research Company, Harold D Messner, Edward J Keeling, October 23, 1984: US04479183 (9 worldwide citation)

A method is disclosed for editing seismic traces gathered by large multichannel collection systems using a pattern analysis of the noise spectrum of each trace. Analysis is limited to only a small time window, say the last second of the trace. In that way a minimum number of quantitative variables a ...

William J Ostrander: Method of attenuating sea ice flexure noise during seismic surveys of permafrost regions. Chevron Research Company, H D Messner, Edward J Keeling, October 7, 1986: US04616348 (9 worldwide citation)

The present invention indicates that in exploration of permafrost regions of the world for oil and gas accumulations, flexure noise can be attenuated by careful placement of the vibratory source vis-a-vis the receiver array during collection of the Vibroseis.RTM.-type data. It has been surprisingly ...
