This study applies the Design of Experiments (DOE) methodology to optimize corrosion inhibitor formulations used in oil and gas production. These chemical inhibitors are multicomponent blends, and their effectiveness is influenced by several variables. One such variable is the ratio of active ingredients, a factor that has received limited attention in prior research. Using DOE, a two-dimensional simplex lattice design was generated to test the ratios of three common active ingredients and evaluate their performance in a statistically optimal way given the present constraints. To reflect real-world application, the study also considered inhibitor effectiveness under varying conditions, including sweet versus sour gas environments and brine-only versus brine-oil partitioned systems. DOE was used to analyze the data with factorial designs. Performance metrics included general corrosion rates and localized corrosion characteristics. Results revealed overlapping optimal mixture regions across conditions and highlighted the minimal impact of partitioning compared to environmental factors. This work demonstrates the power of DOE in chemical formulation, providing a robust foundation for making data-driven decisions regarding corrosion inhibitor product development.
