Challenges for WITSML  QA/QC Real-time data – Need to ensure quality of data for RT decisions without interrupting real time data flow – Well position data - compare real time to plan & geological model  Proprietary data sets – Everyone has them (well test, images, NMR data) – How do we incorporate these into WITSML workflows?  Issues with legacy processes – Operator specific reports, custom data formats  WITSML adoption – Many applications yet to be migrated – Time based data - issues with time zones – Different data access strategies (polling, subscription) for realtime and historical data

Summary WITSML is:  Driving work process improvements now  Generating value today  Enabling interoperation between data providers and software vendors  Enabling fair competition between real time service providers  A key part of BEACON operations at Baker Hughes
