This Presentation
Today’s Oilfield is “data-rich”. We will take a look at
ways we can utilize this information for…
– Increased Production
– Reductions in Operating Costs and Well Failures
– Individual Well Management
– Efficiency in Field Operations
– Efficiency in Computer Operations and Automation

Introduction
• Automation has become widely accepted in the oilfield,
but often falls short of taking full advantage of this
“data-rich” environment.

Understand Changing Well Behavior
• The Challenge is Early Detection
of Production Problems
– Less Downtime More Production
• Automation as a Tool, not just
identifying the problem, but should offer insite to
the solution.
• A Continuous Cycle
– Surveillance
– Analysis
– Planning
– Execution
– Metrics (Key Performance Indicators)
Increased Production

Production Optimization
• Decreased Liquid Loading
Increased Production
– Deploy the right form of artificial-lift
– Optimization Controls at the wellhead
• Goal: Identify problems before
they becomes a failure
– Continuous monitoring
– Automated limit checking
– Automatic Shut-In
– Predictive Modeling

Manage Individual Wells by Exception
• Real-Time / Current Operating Values:
– Tubing pressure, pressure differential, static pressure and gas flow
rates are captured.
– Alarms based on variance from 7-, 28-days averages are generated.
• Off-Line / Nightly Analysis:
– Operating point analysis and Critical velocity analysis are performed
based on the latest well test, current pressure and gas flow readings
using applicable well model.
– Intelligent alarms are generated based on variance between
• calculated and measured operating gas flow rates
• production gas velocity and critical gas velocity at four
points in the well bore.

Optimize Production
• Early Detection of Performance
Degradation by establishing a base-line of
performance.
• Lift Analysis helps determine operating
parameters, setting alarms and detecting
changes
• Automate Comparison of actual (well
test) to theoretical volumes and target values.
