... Abstract Carbon capture and storage (CCS) is an attractive alternative to reduce the concentration of greenhouse gases in the atmosphere with the objective of preventing further increases in global temperature. Accurate estimation of Petrophysical properties and detection of rock types...

..., CaCl 2 , and MgCl 2 . It was intended to simulate different types of produced water, for instance, the salinity of produced water typically found in the North Sea is around 3.5% w. and this salinity level was used for the low-salinity brine. More specifically, the exact salt concentrations for each...

... liquid film using a VOF method. They assumed concentration of different phases is at equilibrium at the interface using Henry's law. They used harmonic averaging diffusion coefficient along with a smoothing procedure to reduce spurious currents. It was shown later by Deising et al. (2016...

... Abstract Alkali Polymer (AP) flooding is a promising Enhanced Oil Recovery (EOR) method to increase oil recovery from reactive oils. It is essential to carefully select the alkali and polymer type and concentration to optimize incremental oil recovery. In addition to the conventional laboratory...
