Heavy crude oil is one of types of the biggest reserves in the world. Heavy oil is a kind of oil that has high viscosity and may causes adversity in naturally oil production. Steam injection emerges towards becoming the most common method used to enhance oil recovery in heavy oil reservoir. This study investigates steam injection with huff and puff method, which is a process of high temperature reservoir zone generation so that the viscosity can be lowered <br /> <br /> <br /> Firstly, model was made by using reservoir simulation. Then, the results of the simulation were tested for sensitivity analysis by using statistic program. This study applies sensitivity study to analyze all parameters that affect injection process and gives an understanding of the impacts that would have been observed with certain viscosity, permeability, porosity, injection duration, soaking time, and injection rate. Based on this study, viscosity is the most impactful parameter due to cumulative oil produced escalation. The viscosity was multiplied 4 times therefore incremental cumulative production went up as 3000 bbl. It is shown in Design of Experiment (DOE), the impact of viscosity is a half of permeability and two times more than injection duration <br /> <br /> <br /> This study is successfully confirmed by final cumulative oil produced and economic evaluation in accordance with oil price per barrel and steam injection prices. Through the calculation of the first reservoir, the project is not beneficially continued. However, the amend of the reservoir characteristic which are permeability that was raised from 200 md to 600 md and porosity from 0.2 to 0.35 may be considered to resume the project and results US$ 76.074.
