3. © Chevron 2005 General Field Overview 3 Large offshore oil field -> expected recovery >1B bbls Multi-layer reservoirs; multiple blocks; water & gas injection operations; artificial lift Mature field; balancing multiple field constraints Production, water & gas injection, overboard water Voidage replacement/minimum pressure requirements Limited well slot capability; dry tree & subsea Ongoing base development activities and new growth opportunities; additional 20-40 year field life Non-operated partner; limited staff working multiple projects Significant non-discretionary activities; data management challenges

4. © Chevron 2005 Current State Inefficient Data Management and Analysis 4 Data sent via email, eQuest, CD and ftp site in form of daily production and drilling reports, presentations & reports, OFM data, log data, etc. Information/documents then saved to our shared drive, while OFM and daily production report data is loaded into ppdm database Individuals access and manipulate data as they see fit and save back to shared drive OFM and some daily production report data pulled into DSS for visualization and analysis; cumbersome and has limited user group Majority of data extracted into individual user spreadsheets for further manipulation, visualization and analysis Often leads to duplication of work Significant time spent managing and manipulating, rather than analyzing data

6. © Chevron 2005 6 Future State Utilizing Spotfire and iRAVE* Creation of a high quality, integrated and collaborative environment that will: enhance the NOJV Teams ability to perform both routine and advanced well, block, reservoir and field level reservoir management; improve decision quality; reduce time spent managing data; and enhance ability to interface with key internal and external stakeholders. *iRAVE – integrated Reservoir Analysis and Visualization Environment utilizing Spotfire

8. © Chevron 2005 8 What is iRAVE Under-the-Hood Look at iRAVE Tool Data Sources Information from a large, heterogeneous set of data sources is brought together in iRAVE (Oracle tables, map files and network flat files) Both structured and unstructured repositories were designed to store the data; significant data clean-up resulted ( a hidden benefit of iRAVE!) Panels iRAVE Release 1 consists of 9 panels with more than 100 visualizations 20% of the visualizations were customized using Spotfire extensions designed by Troy Ruths (HMTL reports, Map Zoom Sync, Maps on Demand) Deployment iRAVE was initially developed for another Chevron NOJV Field and deployed in 2009 5 person team was formed to adapt the original iRAVE application for re- deployment to our Asset; result was delivered in 4 months (able to re-use much of underlying code)

12. © Chevron 2005 Challenges and Lessons Learned 12 Challenges Entire core team, except developer, unfamiliar with Spotfire Team spread across 3 different offices and time zones Timing of project (October to February) Some pushback from Asset Team members Lessons Learned Unclear roles & responsibilities led to initial inefficiencies in project Asset Team required more routine access to tool to ensure it was meeting teams needs Poorly defined review process resulted in rework by developer and IT. Required more routine check point meetings to view tool as it was being built to ensure it was meeting Asset Team needs

13. © Chevron 2005 Best Practices 13 Best Practices Multi-disciplinary project team approach (Asset, IT, Developer) Develop robust and clearly defined communication plan, especially for non co-located teams Identify Asset Team champion with broader knowledge of critical workflows; targeted higher value opportunities and managed scope of initial build Engaged end users on project team positively impacts the design process and greatly increases the effectiveness of the deployment
