Journal Article 2024 01 18 The economic evaluation of oil and gas projects aims to provide decision-makers with a comprehensive estimate of costs and benefits. This study examines the impact of macroeconomic variables, such as interest and inflation rates, on the economic assessment of drilling several gas wells in northeastern Iran. The theoretical framework includes Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP). The importance of accurately predicting these variables for economic decision-making by managers and policymakers is clearly established, with their analysis playing a key role in project evaluation. In this study, the planning of activities and analysis of the construction and operational phases of the project were first conducted. The inflation rate was forecasted using the ARIMA model, and an appropriate discount rate was determined. The pricing of gas and condensates, fixed and variable costs, and project revenues were also reviewed. The economic evaluation was performed using COMFAR software, with a sensitivity analysis to examine the impact of changes in key assumptions. The results indicate positive financial metrics for the project under different production rates, discount rates, inflation rates, and various energy prices, confirming the project's economic viability. https://pbr.put.ac.ir/article_208834_6cc06709b76a605dd4b21acccf111384.pdf
