Analysis of EOR projects and updated screening criteria
Enhanced Oil Recovery (EOR) provides a means to progressively expand hydrocarbon exploitation through scientiﬁc advancements. EOR methods have been proved to mobilize, and induce the ﬂow of oil to producing wells in primary, secondary, and tertiary recovery stages. This work involves the construction of an EOR database based on numerous reported EOR projects. The database lists reservoir rock and ﬂuid properties in addition to other project attributes related to oil saturations, incremental recovery, demography, and project start date. The database provides a proﬁle of worldwide EOR trends. This paper also updates the EOR selection criteria published by Taber et al. in 1996 (Society of Petroleum Engineers (SPE) 35385). Finally, this paper illustrates the relationship of EOR project distribution to key reservoir characteristics. The database can be a vital tool for formulating ﬁeld development plans, ensuring project viability, and clarifying research development priorities.
