The Smart Field
measure-model-control … measure-model-decide-execute
… throughout the asset lifecycle
Smart Systems
From self-guiding missiles to self-replenishing fridges, the basic approach of all “smart technology” is measure-model-control
– measure system properties– model actual vs desired behaviour– derive required correction parameters (adaptive control)– implement control

CERA DOFF: Potential Industry benefits / remarks
Enhanced recovery: 125 billion BOELower operating costs: $4-8 billion/year
Increased production rates: increase utilization 2-6%Lower facilities cost: 5-10% (3-5 years)
Decreased drilling costs: 5-15%But
Benefits are not independent, and they requireIntegration of higher quality data
Significant change in organizations and work processes

Asset Maturity Model (AAM)
Basic - Minimum IT structure, ad hoc processes
Standardized - COTS solutions with minimum of customization
Structured - Configured / customized IT solutions to meet specific needs for the asset
Integrated - Assets networked to operation center(s), EPR systems, wide range of applications and vendors
Optimal - Smart devices (with human oversight), field performance integrated with back office, feed-forward and feedback loops for optimal control

POSC xField Approaches
Understanding / problem identification
- pursue problems will clear (shared) business purposes
Adopt / adapt WITSML
-new Data Types to focus on Production Operations-production volumes, production tests, temperature, pressures
Focus = Architectures + Data
Develop standards via Pilot Projects
Players = oil + service + regulators
Incremental, rapid results

An oil company perspective on Standards
Standards save money!uniform hardware, applications, data save $100 Million/year
Standards lead to better science and increased value
Use standards to address interface issues
It’s better to get common than to be best
Industry standards provide cost effective bridge to the digital oil field
