DIGITAL DATA CLEAN-UP - US OIL MAJOR

OVERVIEW

In 2010, a major US based oil major client obtained a USB disk from an asset in the FSU (Former Soviet Union) containing nearly 70,000 digital files of which over 22,000 had distinct Cyrillic characters in their names. This data was in long complex file folders of which nearly 1000 such folders have Cyrillic content in the path. Some 1,300 key distinct Cyrillic words were detected in the file paths.

Within this data set, there were 18,000 LAS files of which about 15,000 were unique (not duplicates).

The data was delivered to HDS on a USB hard disk for data mining and content analytics.
