The NSTA’s wellbore registration numbering system is a simple code system that provides an unambiguous reference for use in correspondence, cross-referencing between computer databases, and in other information and filing systems.
The NSTA recommends that operators carefully consider their internal wellbore-numbering systems for new projects and design them to avoid confusion with the NSTA’s wellbore registration numbers. Please remember that the full NSTA wellbore number must be quoted on all returns, well logs, reports and correspondence related to a wellbore. An operator’s development wellbore numbering system should be reviewed with the NSTA’s Licensing and Consents department at an early stage in development programme planning.
The terms of this notice cover both offshore and onshore wellbores, although land wellbores may also have an alternate name as a secondary identifier.
Throughout this notice the term ‘platform’ should be taken to include subsea templates and sites where development wellbores are clustered in close proximity, e.g. around a gathering manifold.
