1. Example Case for SOA in Upstream Oil & Gas Rusty Foreman – BP E&P Digital & Communications Technology Service Oriented Architectures, Program Manager

2. 2 The Move to “Smart Fields” Monitor and take action on – “real-time” operations data − Electronic meters or gauges − SCADA (Supervisory Control and Data Acquisition) − Remote servers and “data historians” which are increasingly linked to wide area networks − Advanced analysis, visualization and process control tools The number of systems supplying and consuming real-time data is rapidly expanding

3. 3 The “Spaghetti” Effect Historically: − Point (custom solutions) used to address each new request − Minimal reuse: Each connection rebuilt from scratch IT becomes THE bottleneck

4. 4 Start With Web Services Real-time data transfer Automated notification service

5. 5 Results As of mid-2005, RTAP: 30 locations At least a dozen applications providing data and about the same number consuming data

8. 8 Most Significant Benefit of SOA? - IT & Customers Focused on Core Business Processes

9. 9 The Journey to SOA 1.Experiment with Web Services 2.Begin wrapping legacy applications 3.Define / establish internal Service Oriented Architecture Significant Issues: - Maturity of underlying standards - No common definition of SOA 4.Expand the established SOA beyond the firewall
