In the May 2000 issue of TLE, Chris Liner raised the issue of available bandwidth in seismic data and suggested that it is the lack of low frequencies in recording which limits our ability to properly image the subsurface. In this entertaining article, Liner uses a standard image, Lena, to demonstrate what happens to a familiar image when we lose the high and low frequencies and suggests that perhaps the poor response of geophones to low frequencies is a problem. Those who attended SEG's 2001 Annual Meeting in San Antonio had the opportunity to experiment with “LenaSeis” at the...
