Harvest's upstream asset base offers improved recovery potential in both our conventional and oilsands opportunities. We are well positioned to realize significant short and longer term benefits by employing new technologies and methods to enhance recovery of our large hydrocarbon pools.

Wainwright

• Cretaceous Upper Mannville Sparky Formation
  • 22^o – 24^o API – Medium Crude Oil
• Polymer flood pilot constructed in 2009
  • 13 Injectors
  • 23 Producers
• Technical analysis indicates pool wide recovery could range from 47% up to 60%
• Harvest has 99% working interest
• Water cut decreased from 98% to 90% in some producers
• Largest polymer flood in the world using produced water
• Large OOIP of 122 mmbbl pool; with ~41% recovery to date
• Average daily production of 1,820 boe/d in 2011

Polymer Waterflood

Hay River, B.C.

• Acquired in August 2005
• Bluesky Formation
  
  • 24^o API – Medium Crude Oil
• Large OOIP (239 mmbbl) bluesky pool with very low recovery to date (~9%)
• Harvest 100% working interest
• Winter access only for drilling operations
• Focus on increasing water injection into the formation for improved production and oil recovery
• Future Plans include the drilling of 30 producers and injectors
• Natural gas is processed at the central facility and is re-injected into the reservoir for pressure maintenance or sold

Suffield

• Upper Mannville Glauconitic Formation
  • 15^o – 18^o API – Heavy Crude Oil
• Harvest 100% working interest
• Polymer flood pilot & upgraded water injection systems constructed in 2010 to increase recovery of oil
• Average daily production of 2,950 boe/d in 2011
• Future development may include expansion of polymer flood, step-out, extension and infill drilling in the established pools
• Pool optimization and enhanced recovery projects will target:
  • increased water injection into under-injected reservoirs to support pressure maintenance
  • introduction of polymer flooding to further enhance sweep efficiencies
