The purpose of this study is to prioritize investment methods in oil projects using the Vickor method. The present study is an applied and methodically exploratory research. The criteria and options of the questionnaire were extracted by reviewing the research background and previous studies. Then a questionnaire was developed based on the Likert spectrum and the extracted indices were measured using a single t-test. After confirming these indicators, the second questionnaire was developed based on the pair of pairwise comparisons with 14 questions (criteria) in the form of 4 options to examine the importance of criteria and options. The statistical population includes a number of oil project managers, numbering 250 people. In this study, the Morgan table was based on a sample size of 148 people who were measured by sending a questionnaire virtually to a statistical sample in Tehran and Khark to determine their importance. The sampling method is also simple random. In order to determine the reliability, the incompatibility rate has been used, considering that this rate is less than 1 /. Is indicative of its reliability. Then, the questions were examined through Vicker's method for weighting and prioritizing the criteria. The results showed that in this study, in relation to investment methods in oil projects, financing through financial markets (.838), financing through the capital market (.5914), and co-financing (1159. respectively), respectively. .) And financing in terms of possibility of referral (0855 /.) Ranked first to fourth. Next to present a hypothesis with 4 independent variables discovered (4 options) with the variable of investment in oil projects from the perspective of return on investment (ROA) through autocorrelation test, variance heterogeneity test and regression from the perspective of return on investment (ROA) among Five oil companies were paid. The results showed that there is a significant relationship between 4 independent variables (co-financing, financing through capital market, financing through financial markets, financing in terms of return) and investment in oil projects in terms of return on investment (ROA). has it.
