This study employs the response surface method in conjunction with a user‐defined design to model the solubility of carbon dioxide in different bitumen cuts. Two different sets of data for carbon dioxide solubility in Cold Lake bitumen were considered. Temperature, pressure, and the bitumen cuts' molecular mass were selected as the explanatory variables. Scatter plots were used to determine the appropriate transformations for the explanatory variables. An ANOVA test was considered in a step‐wise manner to select the significant parameters. A second‐order dependency on temperature and a first‐order dependency on the pressure and molecular mass were observed. In addition, a binary interaction between the molecular mass and pressure was observed. The developed correlation modelled carbon dioxide solubility in bitumen cuts with an AARD of 5 % for all the experimental data. The perturbation curve emphasized the strong dependency of solubility on temperature and pressure.
