Background to the Technology
“Primary Production/Depletion” Processes (eg liquid expansion, solution gas drive) →typically ~20% OOIP recovered
“Enhanced Oil Recovery” Processes- “Secondary Production” (Water Flooding)
up to ~60% OOIP recovered- “Tertiary Production” (ie Gas Injection using
CO2, N2, hydrocarbon gases)up to ~70% OOIP recovered

CO2-EOR in North America
Leading EOR process in USA (~50 operations)Operating experience in W Texas since 1972 and >1 billion bbl produced by CO2-EOROnly 2 operations in Canada but of increasing importanceImportance of exceeding Minimum Miscibility Pressure (depth usually >750m)

SACROC Key Statistics
Current CO2 injection rate is 5.1 million sm3/day (~9,450 tCO2/day)Cost of CO2 is ~$20/tCurrent incremental oil production (ie CO2-EOR) is 6,000+ BOPDCost of production of EOR oil is ~$15-16/bblTarget (in 5 years time) 50,000 BOPDField life extended to 2020+
Incremental recovery is ~13-15% OOIP, or ~200 million bblsOperation is economic within fiscal framework

Lessons for the UK 1
CO2-EOR is an established technology with wide applicabilityCO2-EOR makes a significant contribution to production in the USACO2-EOR enables significant recovery of incremental oil and field life extensionStrong parallels to North Sea – security of supply important but needs incentivesLong term commercial contracts exist for CO2supplyCO2-EOR is stimulating a market for CO2No significant technical barriers

Lessons for the UK 2
WAG techniques largely optimisedImportant to have good understanding of geology and miscibility conditionsCO2-EOR requires certain pressure and certain SG of oil to be effectiveCO2 relatively easy to handle in dense phase (supercritical fluid)Separating CO2 and hydrocarbon gases is relatively simple where economics permitStrong industry/government/academia collaborations are very beneficial in international demonstrations
