Production Technologies
Mining and In situ thermal recovery
In situ, extraction accomplished by drilling wells and thereafter injecting hot steam.
Mining production 2004, about 600.000 bbls/d In situ production 2004, about 400.000 bbls/d MiningMining ExtractionExtraction
About 20 % of established reserves Mining, huge open-pit mines combined with large extraction facilities to separate the bitumen from the sand. Less than 75 meters overburden. Recovery rate about 90% InIn SituSitu RecoveryRecovery
About 80 % of oil established reserves In situ extraction removes the hydrocarbons, and leave the mineral behind. Viscosity, permeability and reservoir thickness important. Cyclic Steam Stimulation (CSS) Steam Assisted Gravity Drainage (SAGD) Emerging technologies, VAPEX & THAI Cyclic Steam Simulation (CSS) Steam Assisted Gravity Drainage (SAGD) (20 – 25% recovery rate) (40 – 70% recovery rate)

Bitumen is deficient in hydrogen. Must be upgraded to synthetic crude oil (SCO) to acceptable feedstock for refineries Addition of hydrogen or the rejection of carbon, or both. Upgrading uses natural gas as a source of heat and steam for processing and also as a source of hydrogen. CanadianCanadian ReservesReserves ofof CrudeCrude BitumenBitumen

Large water use (2.5 – 4 units of water per bitumen unit) Large ponds of waste material.
Greenhouse gases, mainly CO2, but also other air emissions such as SO2, NOx, H2S, CO, O3, VOCs PAH etc Greenhouse gas emissions from the oil sands industry may exceed 130 mega-tonnes per year by 2020. Canada has signed the Kyoto treaty! OilOil ProductionProduction InvestmentInvestment AspectsAspects
Oil sands mining projects demand enormous capital investments. Shell has invested more than C$6 billion in the AOSP project. Production costs between $15 – 24! Oil Sands production - A Profitable Business Area !
Already Made And Planned Investments In Oil Sands Production
1996 – 2002 $24 billion (Can.) investment in oil sands 2002 – 2006 $7 billion (Can) under construction. 2007 - $25 (Can) billion, new oil sands projects announced and under evaluation. DifferentDifferent PublicPublic OilOil SandsSands ForecastsForecasts

Conventional Oil Production, Canada + The North Sea OSTRM Oil Sands Production Forecast ConclusionsConclusions
The natural gas supply situation and CO2E emissions are development constraints for the oil sands industry. ??? In situ production - the big question mark ??? The Canadian oil sands industry cannot even compensate for the combined decline of conventional oil production in Canada + the North sea by 2030. The Canadian oil sands will not prevent global peak oil! Question to the IEA: Assuming Venezuela achieves a production of 6 million b/d of heavy oil by 2030, Canada 5 million barrels. Who will produce the remaining 26 million barrels per day of unconventional oil?
