Scoping tools such as that developed by Kinder Morgan for CO2 floods provide operators with a useful intermediate-level assessment of the potential suitability of an Previous HitoilNext Hit field for Previous HitenhancedNext Hit Previous HitoilNext Hit Previous HitrecoveryNext Hit—intermediate between applying simple screening "rules of thumb" and going to the expense of applying a full-fledged field simulation model. An important limitation of these scoping tools, however, is that they are based on experience with EOR at a given field. If the particular field being assessed is not sufficiently "similar" to the field used to build the scoping tool, then the tool's predictions will be unreliable. An analysis of CO2-flood experience at fields in Wyoming suggest that these fields in fact differ substantially from the fields (located in West Texas and Oklahoma) underlying the KM tool, which points to the need for a Wyoming-specific scoping tool. The tool currently under development at the University of Wyoming's Previous HitEnhancedNext Hit Previous HitOilNext Hit Previous HitRecoveryTop Institute will address this need. Other limitations of the KM tool are its exclusive focus on a single EOR method and its assumption of a fixed price path when assessing the economic viability of EOR. In contrast, the EORI tool will allow operators to assess non- CO2 methods as well, and to explicitly account for price uncertainty when performing the economic analysis.
