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

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

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.
