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)

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.

Individual Well Management

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.

Efficiency in Field Operations

• Less Windshield Time only travel to

the wellsite when it requires immediate

attention

• Alarm Notification and

Management 24/7/365 monitoring of

production

• Daily Production Reporting automated generation and email delivery

• Proactive Maintenance review of trend

reports and operational data to identify problems

before they occur.

• New & Lower Cost Wellsite

Controls & Equipment faster processing,

more local storage, more I/O, …

Computer Operations & AutomationEfficiency in Computer Operations and Automation

• Reduced Installation & Maintenance Costs

• PC-Based Platforms

• Integrated Tools

• Reduced Data Management Costs

• $/Mb of data little factor, store years of data.

• Common SQL Databases

• Move from older proprietary control systems to

open systems architectures & interfaces

• Data moves easily thru the enterprise
