A hierarchical sequential Gaussian cosimulation method is applied in this study for modeling the variables with an inequality constraint in the bivariate relationship. An algorithm is improved by embedding an inverse ...
Low salinity waterflooding (LSWF) and its variants also known as smart water or ion tuned water injection have
emerged as promising enhanced oil recovery (EOR) methods. LSWF is a complex process controlled by several ...
To date, the accurate prediction of tunnel boring machine (TBM) performance remains a considerable challenge owing to the complex
interactions between the TBM and ground. Using evolutionary polynomial regression (EPR) and ...
Miscible carbon dioxide (CO2) flooding is a well-established and promising enhanced oil recovery (EOR)
technique whereby residual oil is recovered by mixing with injected CO2 gas. However, CO2, being very
light and less ...
