Abstract
The thermal method is the most popular method applied to oils with high paraffin levels. Steam flooding is one method of thermal EOR that is considered effective in increasing oil recovery by reducing oil viscosity. The success of screening criteria steam flooding method can be determined by investigating the most dominant parameters in increasing recovery factors. This study to determine the parameters that most contribute for recovery factor. The study using CMG STARS numerical simulation for reservoir modeling. Fractional factorial design method using for check the reactivity of each steam flooding parameters. Reservoir modeling using Cartesian grid ang six parameters tested. On draft fractional factorial design with 16 runn. The most dominant parameter that can increase the value of oil recovery factor in the injection of steam flooding in black oil wells is the steam injection rate with the smallest P value 1,23992× 10−8 and the largest coefficient with a positive value of 7,56. The second dominant parameter is the well pattern with a P value of 1,22068× 10−6and a coefficient of -4.45. Then followed by permeability in the range 700-1500 Md with a P value of 0.00171222 and a positive coefficient of 1.72. and temperature with a P value of 0.053633 and a coefficient of 0.99. Meanwhile, steam injection volume and steam dryness are insignificant parameters in this study based on a 95% confidence level.
