Investigation of Crude Oil Compositional Changes During CO2 EOR
The present task is to investigate the effect on the molecular weight distribution of produced oil during CO2 enhanced oil recovery (EOR) and associated CO2 storage and, by extension, the composition of crude oil hydrocarbons left in the reservoir. Two experimental approaches have been (and will be) utilized, including 1) the temporal collection and analysis of the produced crude oil before and after CO2 injection and appearance at the production wells and 2) laboratory-based sampling and analysis of the hydrocarbon composition found in the CO2-dominated miscible phase when Bell Creek crude oil is exposed to CO2 at reservoir temperature and pressures.;View/Download Document
