    Introduction John LeGrow

    Pilot Production Gerry Hampshire

    Steam Chamber Observations Glenn Fung

    4D Seismic Interpretations Kim Head

    Status and Future Plans Gerry Hampshire

    Conclusions John LeGrow

  • Accomplishments since January 2002: Testing Sucker Rod Pump lift systems

    Continued reducing sub-cool temperatures in all 3 wellpairs

    Modified plant to allow individual well testing

    Acquired additional 4D seismic

    Introduction

  • Continued learnings : Observation well data, production volumes,

    and seismic demonstrate continued steam chamber growth

    Demonstrated record production performance as a result of lower sub-cools

    Appears that operating pressure may influence steam chamber rise rate

  • Main Pilot Objectives

    1. Thief Zone Impact on SAGD Process

    2. Deep Reservoir & Low Operating Pressure Effects on Artificial Lift & Performance

    3. Understand the effect of mudstone breccias and thin mudstone horizons on steam rise and bitumen drainage production

    4. An additional objective was to drill, start up & operate a 700 m commercial length well pair at low pressure

  • Operational Summary

    Artificial lift system was changed in both the P1 and P2 wells during the year

    Modifications within the plant allowed additional volume throughput

    Modifications within the plant allowed individual well testing

    Excessive downtime during the year was due to artificial lift failures, mechanical problems encountered during the turnaround, and regional forest fires

  • Thief Zone ImpactApparent Steam Chamber Distance to Thief Zone has increased from 15 m to 25 m based on OB22. Breakthrough timing is influenced by steam chamber pressure.Have recently run cased hole logs to help determine saturations of the steamed interval. In the process of analyzing the results.Breakthrough will occur, but timing difficult to predict, meanwhile good production and associated steam chamber growth continue.

  • Pro-4D offers modeling capability

    This Pro-4D model of the OB17 well shows the predicted AVO

    effect of gas coming out of solution. Note

    minimal change predicted at zero

    offset.

    Here we see the predicted change in

    the stack 1998-2001.
