Production from heavy oil reservoirs is a challenging task and needs special design. In this study, oil well production was maximized using nodal analysis for a field of study. The optimum tubing and flow line sizes are selected by means of pressure traverse. The wellhead pressures and choke sizes were computed by finding the inflow and outflow of the flow line. Several reservoir parameters for the purpose of observing the effects of pressure depletion were investigated. Initially, fluid description, flow type, type of artificial lift, well type whether offshore or onshore, and well completion is selected. PVT data are entered, and the matching process requires some parameters such as reservoir temperature, with the corresponding pressure to be produced. Then, IPR is selected and found depending on the reservoir data. The calculated data should be matched with measured data using VLP/IPR quality check to make sure that the models emulate the actual well data. If there is no matching, entered PVT data should be checked until matching is found. If performance is accepted, the operating point is found at the intersection of IPR and VLP and that is before optimization. The optimal values are entered into the design and computing the operating point after modification if results are not as expected, the modification process is checked again until reaching satisfactory outcomes and this project's goals are met. The results of the study revealed that there was no fluid flow before the gas lift or ESP operation. All the methods studied revived well-X. The significant result was the ability of GL which was 1509 2708 STB/ day, and ESP has achieved the highest oil production of 2708 STB/ day. The economic range was found to be [(2-4.2), (2- 3.6), and (1-2.7)] MMSCF/D for CH4, N2, and CO2 respectively. That led to an economic injection rate of 3, 3.4, and 2.4 MMSCF/D for CH4, N2, and CO2 correspondingly, and for ESP is 180,229.4$ which is the highest revenue compared with the GL method. Finally, the findings contribute to oil and gas by considering greenhouse gasses. Also, it recommends the possibility of using another gas injection type and another artificial method, then compared with these results to find the best method for heavy oil.
