Annex A: Organization Codes

Last Updated 3 Mar 2003

1 - Assignment of Organization Codes

This appendix contains a list of organization codes assigned by POSC for use in RP66. Organization codes primarily identify organizations, but are also used as identifiers of meta data resources to which RP66 Logical Files may refer, for example: Several of the organization codes in this appendix are historical in nature and reflect the well log origins of RP66. Organization codes are assigned by POSC which maintains the current list of codes. To request a new organization code, contact POSC
