Well log channel matching

A system, comprising:

• a memory coupled to a computer processor;
• a repository configured to store a set of well log channels and an unknown well log;
• and
• a well log channel matcher, executing on the computer processor and using the memory, configured to:
• calculate a first set of hash values for the set of well log channels,
• extract a well log channel snippet from the unknown well log channel,
• calculate a second set of hash values for the well log channel snippet,
• identify, for the unknown well log channel, a matching well log channel by searching the first set of hash values with the second set of hash values, and
• store, for the unknown well log channel, a channel context corresponding to the matching well log channel

A non-transitory computer readable medium comprising instructions that, when executed by a computer processor, perform operations comprising:

• calculating a first set of hash values for a set of well log channels;
• extracting a well log channel snippet from an unknown well log channel;
• calculating a second set of hash values for the well log channel snippet;
• identifying, for the unknown well log channel, a matching well log channel by searching the first set of hash values with the second set of hash values;
• and
• storing, for the unknown well log channel, a channel context corresponding to the matching well log channel.
