IDENTIFICATION AND CLASSIFICATION OF SEISMIC REFLECTION VELOCITY PROPERTIES ON SEISMIC REFLECTION SECTIONS

摘要

Velocity information is superimposed on a conventional seismic reflection section using either a transparent overlay or an optical projection. Isodepth lines are used for conventional reflection time sections and iso-time lines are used for reflection depth sections. The isodepth lines could be in the order of every 1000 feet but would depend on the time scale used on the reflection time section. Iso-time lines spaced ten milliseconds apart could be appropriate for a long depth scale and fewer lines could be used for a smaller scale.
