Abstract
This study presents an approach to optimize the design of hydraulic fracture treatments in the low-permeability area of the Lower Miocene sandstone reservoir in the Cuu Long Basin of southern Vietnam. Six major design variables influenced the fracture length, which may enhance oil production when the fracture length was maximized. Thus, the fracture length was analyzed using the central composite face design based on statistical modeling, which is an experimental design for response surface methodology. The results showed that a maximum fracture length of 828 ft was obtained at an injection rate of 30 bpm with an injection time of 79 minutes. The slurry concentration at the end of the job was 8.6 ppg, the leak-off coefficient was 0.0023 ft/min0.5, and the fracture height migration to the pay zone height ratio was 1.065.
