Earl F Herkenhoff, William J Ostrander: Method for the interpretation of envelope-related seismic records to yield valuable characteristics, such as gas-bearing potential and lithology of strata. Chevron Research Company, H D Messner, E J Keeling, February 25, 1986: US04573148 (23 worldwide citation)

In accordance with the present invention, progressive changes in amplitude as a function of offset of common gathers can be more easily identified by displaying difference envelopes of "near" and "far" amplitude vs. time traces of each gather, as a function of common groups of centerpoints. A signif ...

Chevron Research Company, H D Messner, Edward J Keeling, February 11, 1986: US04570246 (16 worldwide citation)

In accordance with the present invention, progressive changes in amplitude as a function of offset of common gathers can be more easily identified by emphasizing the degree of amplitude variation between traces of each gather along a seismic line, and after generating semblance coefficients, display ...
