Economics and Potential for Mobility Control Methods for CO/sub 2/ Floods in the Rocky Mountain Region
A levelized cost procedure is used to determine the profitability of carbon dioxide flooding in the Rocky Mountain Region for non-waterflooded fields, and of the use of thickening agents for mobility control. The effects on production of changing the mobility of the injected CO/sub 2/ are estimated by use of a correlation developed by Claridge (1) from his analysis of the literature on developed five-spot patterns. The procedure shows that mobility control can be applied profitably to carbon dioxide floods. Greater profits result from operating at lower mobility ratios. The effect of varying critical operation and financial parameters on the profitability of carbon dioxide floods is investigated. The profitability of the project is highly dependent on the cost of carbon dioxide. The oil price, oil price escalation rate, carbon dioxide cost escalation rate, and discount rate for discounting future cost and revenue streams affect the profitability of the project by an order of magnitude less than the cost of carbon dioxide. However, for conventional carbon dioxide floods, carbon dioxide recycling is important and the recycling affects profits more than the parameters just mentioned previously. The cost, concentration, and escalation rates of mobility control agents are also important factors which affect the profitability of mobility controlled carbon dioxide floods. The fixed charge rate for capital and the operation and maintenance cost escalation rate affect the profitability of the flood but these parameters play a far less significant role than any of the other factors described above.
