8. Paradigm Key Product Brands Data Management and Interoperability

9. The εpos 5-layer model

10. What is εpos? Data Repositories optimized for E&P –Designed for complex structures and large data volumes –Can host data for a large spectrum of applications and disciplines A Middleware Framework –Supporting distributed data management –Multi-vendor, multi-data model, multi-platform –Independent of repository architecture (relational, hierarchical, flat) –Simple access using a powerful Application Programming Interface Data Management Applications –Administration of projects, repositories, users and groups –Browsing tools for broad, multi-vendor networked repositories

11. Tight & Loose, or Loose & Tight? Application Single Database Application Visualization Application Modeling Application Inter-Process Communication Traditional: Tight Data, Loose Applications Distributed Data Management Visualization Canvas Solid Earth Modeler Application εpos: Loose Data, Tight Applications

12. Keep the data where it belongs Locate data where it makes sense, under its own rules –Seismic in multi-terabyte disk farms –Engineering on Windows servers –Databases from other vendors for certain asset teams, etc.. Catalog the existing data repositories –Register over the entire network all data sources E&P projects will point to a list of selected repositories –Build a project by associating data from different sources. Distribute the management of data –Synchronized services available on all systems storing data –No single point of failure

13. Benefit: Scalable to any company size εpos can run on a single laptop, with a single user –No onerous administrative overheads εpos can run in a complex environment –Heterogeneous hardware platforms –Great diversity of data in different data stores –Connected to third-party repositories –Complex user authorization patters including specialists, etc… –Administrators can have overview the available services Mobile systems included –Disconnection and re-connection of mobile systems –Automatic synchronization with the other εpos servers
