Abstract

"Most carbonate formations prove to be oil-wet due to oil aging effect. Therefore it is essential to employ wettability alteration methods for a more effective enhanced oil recovery process. It is confirmed by researchers that surfactant treatment has positive effects on wettability alteration of carbonate rock, from strong oil-wet to intermediate wet or to even weak water-wet. A number of experiments have the same conclusion and yet, a systematic screening guide development with the support of sufficient data analysis is lacking.

This study involves screening guide development for surfactant-induced wettability alteration method. 199 experiments collected from published literatures are analyzed in this work. Database quality, parameters selection and data visualization are concerned. Box plots and cross plots are utilized to discover inconsistent data and special cases. Parameters significance determination is achieved by multiple regression analysis. Histograms and box plots are used to exhibit the range and distribution of each selected parameter. Eventually, three types of surfactants: anionic, cationic and nonionic surfactants are compared in terms of parameters' 09 ranges due to their distinct characteristics using radar charts, histograms and bar charts"--Abstract, page iii.
