Abstract: There are many parameters in seismic data display, "WYSIWYG"(what you see is what you get) is a basic demand for any visual software. But the section display function in Geoframe software changes the seismic relative amptitude, that is not permitted without the user's agreement. This false is verified by model data and self-contradiction in Geoframe software. The reason for this error may be poor test, unexpected AGC or software "Bug" etc. It is suggested that attention must be paid to this software when proceeding in seismic attribute analysis and lithological interpretation.
