Application of Catastrophe Theory to Integrative Evaluation of Reservoirsby CO2 Miscible Flooding Process

Abstract

Abstract: A new assessment method combined catastrophe theory and fuzzy mathematics is established and applied for the first time to evaluate and select the candidate of CO2 miscible flooding reservoirs. Based on the subordinate functions in it, the comprehensive values of all candidate reservoirs are calculated. Case study shows that the results evaluated by such a method is accordant with other evaluation methods, ensuring the veracity and creditability of the results and avoiding the randomicity and troubling of hierarchy process, factor analysis, fuzzy comprehensive appraisal and other assessment methods.

Key words: CO2, miscible flooding, catastrophe theory, fuzzy mathematics, subordinate function
