Method and system for identifying analogous well log data while maintaining confidentiality

Abstract

A method for identifying analogous well log data while maintaining data confidentiality. Well log data files are gathered and processed to extract patterns from them. For each pattern extracted, an alias identifier is created and stored to link the pattern back to its original well log data file. A test well log data file is selected, and a test pattern is extracted and pattern-matched against the stored patterns. A set of alias identifiers associated with the best matches from the pattern matching is returned. The alias identifiers are used to request access to the well log data files associated with the best matches, without exposing confidential information such as original data, ownership, well name and location.

Dependencies are inferred from the claim text.
