Abstract:
A critical review of previous studies is presented based on the contextual research
background of surfactant flooding in this study. The parameters focused on
achieving the analysis include permeability, salinity, temperature, and viscosity from
different surfactant flooding operations. The principal theme of this review was to provide
the regression analysis technique that may adopt to analyze the collected data and
conduct contextual research. The set of analytical discussion is accomplished by extracting
and plotting the basic parameters against recovery at Original Oil in Place (OOIP)
and tertiary stages. Furthermore, the success rate of such studies is compared to the
grounds of oil recovery efficiency at different stages. Moreover, the failure of the surfactant
flooding project can also be ensured by the outcomes of this study.
It is revealed from this study that the recovery efficiency of surfactant flooding can be
obtained maximum at lower permeability ranges, however, other parameters such as salinity
and temperature may possess some influence on recovery. In fact, the fluid viscosity
of reservoir fluid is inversely rated to recovery. The salinity, temperature and viscosity
ranges for efficient surfactant flooding ranges may drop within the range from 1400
to 132606 ppm, 25 to 126 °C, and 1.9 to 150 cP, respectively.
