Enhanced oil recovery (EOR) methods are adopted when the reservoir is not auto-sufficient energetically or even after secondary oil recovery and the reservoir is not producing satisfactorily. This article aims to perform a literature review of EOR methods, starting from the applied techniques worldwide in onshore fields and proposing implementation in Brazilian onshore scenarios. This initial work studied polymer flooding combustion in situ and cyclic steam in onshore fields. The most promising studied method was combustion in situ due to its higher recovery factor. However, further studies are necessary to understand better more cases of EOR methods applied in onshore scenarios.

This article aims to carry out a literature review of the different experimental methods for determining MMP, presenting a comparative analysis between slimtube, rising-bubble (RBA) and coreflood. Each experimental method was evaluated and understood. A critical analysis was performed from design, operation and application to the parameters in each method. Because it is visual, the RBA allows more precision and repeatability than the slim tube and coreflood, because it has fewer differences between their experimental designs. In addition, when dealing with the experiment time factor, the RBA is also superior to the other methods, taking hours to determine the MMP.
