The Surfactant Huff'n'Puff Method is a newly applied EOR method which yields higher efficiency of enhancing oil recovery than the conventional one by injecting surfactant to the producer well instead of injector well. The cycle consists of surfactant injection, temporary well shut-in while letting the surfactant soaks causing more oil extraction around the well, and eventually production with more oil rate than the natural one. Those sequences are performed until reaching its economic limits. <br /> <br /> Advantages are obvious, particularly on significant cost efficiency due to less-complicated surface facilities and no injector well needed. Moreover, surfactant could react directly to the reservoir rock near wellbore, reducing chemical degradation as fluid moves further. As we know, the main quality of surfactant fluid to displace more oil is its sustainability in time and temperature while flowing through reservoir rocks. If the surfactant fluid flows throughout long distance between injector and producer well, it will be adsorbed and the only fluid that will reach the producer well is water with no-surfactant at all. Therefore, in order to increase the effectiveness and economic value, surfactant Huff'n'Puff method is proposed. <br /> <br /> This study focuses on determining reservoir criteria in which this method can be optimally applied using CMG™ reservoir simulator. Besides, this final project also provides a predictive model to analyze the impact of surfactant Huff'n'Puff, method by performing further sensitivity studies. Subsequently, practitioners can forecast the additional Recovery Factor when this method is applied. The calculation result from proposed predictive model is verified with calculation result from simulator.
