Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Summary In the abstract the compensation methodology of upper-layer anomalies influence at the stage of seismic data processing are described and tested. Compensation had consisted in removing the low-frequency dependence of seismic AVO attributes and the dominant frequency on changes in surface relief. Application of the proposed methodology has significantly improved the quality of seismic data, increase the reliability of geological targeting and search for the missed perspective objects.
