API (American Petroleum Institute) Numbers or US Well Numbers

[forestknutsen1]

Does anyone know a good source for county codes used in API numbers in US well naming standard? I am looking for Alaska in particular.

I did find this old document on it but it is quite dated:

Also, I see that as of 2010 PPDM is managing the standard. I would love to just use their site but they want a $100 for a membership.

It would be ideal if some place there is GIS data for this...  or would it just be best to get the PPDM membership.

Thanks for any suggestions.

PPDM​ is in fact the best source for this information. May organizations have corporate memberships. All one needs is a email address from the corporation that holds the membership to get access.
