Collaborative Digital Surveillance: Improving

Decisions Through Visualization Technology

Stephen SmartSubsurface Modeling Concepts, Inc.

Surveillance Objectives

• Leverage the knowledge and experience of the multi-disciplined asset team in order to reach essential value added goals which are burdened with complex non-unique solutions.

• Make decisions efficiently and expediently• Review results of various methods used.• Bring the best results forward as “Best

Practices”.

“Expanding the use of new-generation digital technologies [remote sensing, visualization,

intelligent drilling/completions, automation, data integration] can potentially increase world oil

reserves by 125 billion barrels”

“The bits and bytes will work, but the biggest challenge relates to adoption and assimilation –

people changing how they work”

Observed Results of Collaborative Digital Surveillance

• Improves Productivity Among Multi-Disciplined Asset Team and Field Operations

• Uses Visualization to Enable Team Collaboration• Better Decisions Faster and Cheaper• Provides a Common Platform to Communicate• Leads to Increased Production and Reserves • Promotes Cross Functional Training and Overall

Ownership Between Team Members

Spotfire Added to the Arsenal

• Outside of Group Meetings:– Integrates most of the data to be used in

surveillance reviews.– Captures Anomalies (good and bad) as potential

opportunities.– Provides analysis of methods that work well and

those that fail.

• During Group Surveillance:– A quick look back from 30,000 feet, prior to making

a final group decision to act (or not).

Reservoir Examples

The Future of CDS• Centralized work rooms with digital projectors and multiple PC’s

• Re-alignment of resources, culture, with emphasis on new skill sets

• Multi-Site Collaboration Facilitated by:– Increased band width technology– Decrease in the cost of technology– Thin Client technology– Synchronized Graphics Display technology

Advantages

• Bridges geographical barriers• Less set up time, quicker system access • Reduce overhead costs “do more with less”• Total system cost approx. $90 K• Reduced travel time and costs
