“…In this case, low residual oil saturation is always expected. Moreno et al (2011) reported that gas flooding promoted lower residual oil saturation than water flooding based on coreflood experiments. Lazreg et al (2017) has demonstrated the benefits of two-phase and three-phase hysteresis in reducing the water and gas mobilities, increasing oil mobility, and reducing the residual oil saturation as compared to water or gas flood.…”

Water alternating gas (WAG) injection process is a proven EOR technology that has been successfully deployed in many fields around the globe. The performance of WAG process is measured by its incremental recovery factor over secondary recovery. The application of this technology remains limited due to the complexity of the WAG injection process which requires time-consuming in-depth technical studies. This research was performed for a purpose of developing a predictive model for WAG incremental recovery factor based on integrated approach that involves reservoir simulation and data mining. A thousand reservoir simulation models were developed to evaluate WAG injection performance over waterflooding. Reservoir model parameters assessed in this research study were horizontal and vertical permeabilities, fluids properties, WAG injection scheme, fluids mobility, trapped gas saturation, reservoir pressure, residual oil saturation to gas, and injected gas volume. The outcome of the WAG simulation models was fed to the two selected data mining techniques, regression and group method of data handling (GMDH), to build WAG incremental recovery factor predictive model. Input data to the machine learning technique were split into two sets: 70% for training the model and 30% for model validation. Predictive models that calculate WAG incremental recovery factor as a function of the input parameters were developed. The predictive models correlation coefficient of 0.766 and 0.853 and root mean square error of 3.571 and 2.893 were achieved from regression and GMDH methods, respectively. GMDH technique demonstrated its strength and ability in selecting effective predictors, optimizing network structure, and achieving more accurate predictive model. The achieved WAG incremental recovery factor predictive models are expected to help reservoir engineers perform quick evaluation of WAG performance and assess a WAG project risk prior launching detailed time-consuming and costly technical studies.

“…In addition to physical experiments, many component models used for CO 2 flooding have been established, and numerical simulation technology has also been widely used in the evaluation and prediction of the effects of CO 2 flooding. By establishing the two-dimensional plane model and three-dimensional model and using computers to simulate the displacement process, the efficiency of CO 2 flooding and its influencing factors under different conditions can be evaluated, which can provide reasonable guidance for the implementation of carbon dioxide flooding [34][35][36][37] . The heterogeneity has a great influence on the EOR (Enhanced oil recovery) effect of CO 2 flooding, the fluid distribution in the process of oil displacement has a good correlation with the permeability of rocks.…”

Latin America possesses expansive natural resources, which has attracted scientists from several areas to study means of improving the use of these resources. Supercritical fluids have been used for such purposes in many technological applications. Therefore, this paper provides an overview of Latin America scientific findings on supercritical technologies. Web of Science and Scopus were used as reference databases to search for information dated from 2004-2013. The Latin-American studies were classified into 6 main areas: extraction & mathematical modeling (57%), emerging applications (15%), thermodynamics & fundamentals (9%), reviews & perspectives (8%), reactions in supercritical media (7%) and analytical applications (4%). A compilation of scientific documents from 1994-2003 indicates that supercritical technology has progress greatly over the last 10 years in the major scientific countries in Latin America, such as Brazil, Argentina, Chile, Mexico and Colombia. These advances are associated with the development of new research subjects. Emerging applications, such as micronization and the encapsulation of nanoparticles, adsorption processes, gas sensors development, power generation and bioresidue hydrolyzation, are reported.
