After 3d high resolution seismic data of Yacheng 13-1 structure were inversed using restriction sparse pulse inversion, data volume of full-frequency band absolute wave impedance was gained.

Results are readily displayed and allow the user to quickly understand duplicated values or drill back into the full frequency distribution for single or multiple columns as Figure 11 shows.

We also looked at the impact related to frequency of searching, full-text indexing, and whether mail documents are filed or kept in the Inbox.
