Abstract

Hydraulic fracturing is an effort to increase the well’s productivity by injecting the fracture fluid at a pressure higher than the formation fracture pressure to create fractures or flow the fluid into the wellbore line. This study uses reservoir simulation software (GEM CMG) to model the reservoir, then running 152 scenarios using CMG-CMOST and performing a sensitivity analysis using Response Surface Methodology (RSM) on Minitab Statistical Software to facilitate the selection of hydraulic fracturing parameters that will be applied to the field. This sensitivity study was conducted on seven parameters, in situ stress, fracture conductivity, fracture half-length, fracture spacing, fracture width, permeability formation, and Poisson ratio. Variables that significantly affect the response if Pvalue ≤ α (0.05). The results showed that fracture half-length was the most influential parameter of 98.02% followed by permeability formation 95.19%, permeability*permeability interaction 92.37%, %, fracture width 89.54%, fracture half-length*fracture width interaction 86.72%, fracture half-length*fracture half- length interaction 83.89%, interaction fracture half-length*permeability formation 81.07%, fracture width*permeability interaction 8.24%, fracture width*fracture width interaction 75.42%, and Poisson ratio 72.59%.
