Paper Number: SPE-214451-MS
... the driving force is the concentration gradient (see Equation 1 ) ( Ahmadi, et al., 2021 ). Thus, the diffusive flux occurs from the high-concentration zone towards the low concentration zone. Other driving forces which can be described similarly are pressure and temperature gradients, electrical potential...

... by adding bacterial growth and decay. GEM does not support the Monod kinetics which describes the microorganism's growth; thus, a tuning of the Arrhenius equation parameters was performed to match the Monod formula over the substrate(s) concentrations of interest. Finally, the Arrhenius formulation...

... on mass transfer. The increasing residual gas reduces the partial pressure and solubility of CO 2 . As a result, the concentration and density difference between saturated water and fresh water are mitigated, leading to the suppression of the driving force for CO 2 diffusion and convection. Accordingly...

Normally, the bulk rheology measurements only evaluate the viscosity versus shear rate at a specific reservoir temperature and limited polymer concentrations when evaluating a polymer product for EOR application. Hence, the database generated from polymer...
