Enhanced oil recovery screening is considered as an important first step towards evaluating a potential EOR technique for a candidate reservoir. A vast amount of research is continuously been conducted in EOR. Therefore, it is imperative to update the screening criteria regularly.
This study involves updating the screening criteria for surfactant polymer flooding for field projects dataset and laboratory dataset. Many of the screening criteria for surfactant-polymer flooding in the literature were achieved on the basis of data collected from the EOR surveys published biennially in Oil & Gas Journals. However, these datasets contain problems like missing data and inconsistent data. Data quality has not been addressed in the previous works in the literature on screening criteria. The objective of this study was to update achieve a range for 42 surfactant-polymer projects after the data. Another comprehensive work of this study was to establish a range for laboratory dataset consisting of 200 experiments.
Box-plots and Cross-plots were used to study the dataset for special cases or inconsistent data. Histograms and box-plots were used to exhibit the distribution of each parameter and present the range of the dataset.
Eventually, the ranges for field projects were compared with the screening criteria previously published in the literature. Also, the developed screening criteria for laboratory work were compared with the developed screening criteria for oilfield projects --Abstract, page iii
