Abstract: Recent advances in enhanced oil recovery (EOR) technology create new opportunities for CO2 sequestration. This paper proposes a technical-economic model for underground storage Of CO2 emitted by a fertilizer industry in the Northeast of Brazil, in a hypothetical mature oil reservoir through EOR operation. Simulations based on mass, energy and entropy balances. as well as economic analysis, were assessed for the process of CO2 sequestration combined with EOR. This model takes into account the energy requirements for the whole CO2 sequestration process. as well as the emissions inherent to the process. Additionally. a breakdown cost methodology is proposed to estimate the main financial determinants of the integrated EOR with CO2 sequestration (Costs Of CO2 purchase, compression, transportation and storage). Project evaluation is derived from a cash flow model, regarding reservoir production profile, price and costs, capital expenditures (CAPEX), operating expenditures (OPEX), carbon credits, depreciation time, fiscal assumptions etc. A sensitivity analysis study is carried out to identify the most critical variables. Project feasibility. as expected, is found to be very sensitive to oil price, oil production, and CAPEX Moreover. there is the contribution from the mitigation of the greenhouse gas (GHG) by storing a significant amount of CO2 in the reservoir where it can remain for thousands of years.
