CDA and Schlumberger maintain a set of operational procedures which are used to determine user behaviour with regard to interactions with the CDA DataStore. The procedures cover data submission, entitlement setting, data sharing and transfers of ownership. The procedures differ from the CDA Standards in that they are geared very much to operational needs and are specific to the Schlumberger system. As these procedures change and evolve, the Operations Procedures Document is revised. The current revision is found in the Members Section Operations Procedures Document.
