Geodetic Framework – Conclusions


Geo-spatial data should be treated as an equal to trace data instead of hiding in its shadows.  Business decisions are made on where to drill based upon an interpretation performed on the trace data.  The positions assigned to the trace data will directly impact the success of a drilling project whose well location is selected from it.  The seismic survey data used to determine traces locations (common mid points) are either; source positions and receiver positions or bin grid polygon definition.  Errors in either these positions or polygon definitions will create early contributions to the geo-spatial error budget.  Therefore accuracy and integrity cannot improve but only deteriorate.

The geo-spatial error budget must be understood and kept to a minimum.  This can be achieved with diligent data management and a structured quality assurance system.  Appropriate business rules adopted within the assurance system will ask the right questions of the data and ensure the data metrics reaches a level where data integrity is not compromised and ambiguity removed.
