Global Unique Well Identifier (GUWI) Service

1. Global Unique Well Identifier(GUWI) Service

2. Objectives • Establish an industry standard unique identifier for all known wells in the world • Create a Master Well Index containing the unique identifier together with sufficient common attributes to enable matching of wells to the file • Provide an industry service for Well Registration and Matching to: • assign unique ids to new wells • match existing wells to identifiers already in the master index

3. Benefits • The Well Master Well Index (MWI) will: • Provide a single source for all known global wells. • Enable clients to assign standard unique ids to proprietary well files to minimize ongoing integration issues. • The Well Registration and Matching service will: • Enable IHSE customers and other operators, data vendors, and service providers to assign standard unique ids to their well files for delivery to industry.

Master Well Index Structure • We have completed the design, development and loading for R1 of the MWI based upon extensive client discussions and review • Future releases will be designed in combination with the WISWG • The MWI will be maintained as a single table with one record for each unique well. • There will be 4 main components: • GUWI • Common Attributes • Status • Registration

Deliverables For our customers: • We will deliver the full MWI for the regions that they subscribe to. • We will deliver records flagged as public for the areas that they don’t subscribe to. • The proprietary content of the MWI will remain the property of IHS Energy covered by existing data contracts.
