... where μ o and μ w are the oil and water viscosities respectively, μ is the oil-water viscosity ratio, and k ro is the oil relative permeability. We can express the fractional flow at the wellbore in terms of the relative permeability functions, which allows including the effects...

... Abstract Geological storage of carbon dioxide (CO 2 ) in the brine aquifer is a dual-benefit strategy for mitigating greenhouse gases and advancing carbon capture and storage (CCS). Meanwhile, the gas-water relative permeability (RP) of CO 2 and brine provides fundamental insights into flow...

... Abstract The three-phase relative permeability of oil, gas, and water place a significant practical emphasis in the study and evolution of compact sandstone condensate gas traps. However, most investigations on itare relied on forecast patterns that make an effort to appraise it from...

... thermodynamic equilibrium. To account for both, reservoir water with CO 2 is put in the tank until the thermodynamic equilibrium is established. Objectives Steady-state coreflood test is a widely accepted industrial method to determine relative permeability (K r ), but the capillary pressure (P c ) must...

... continuously. We conducted high rate tests for selected wells to monitor well productivity impairment from the condensate banking. This production data was history-matched with a compositional sector model by applying Local Grid Refinement (LGR) and Velocity-Dependent Relative Permeability (VDRP) to account...

... Abstract Artificial intelligence (AI) has proven to be the smartest predicting tool in the oil and gas industry. In this paper, Artificial Neural Network (ANN) algorithm was applied to build two new empirical correlations to predict relative permeability profiles of oil-water two phase flow...

... with in a compositional simulation. In this paper, considerable research has been conducted on compositional models, especially miscible gas flooding models, by identifying the near-miscible/miscible state and its influence on relative permeability. This paper describes a multi-component, three-phase, compositional...

Abstract A detailed comparison is made of the more recently developed phenomenological 2-phase Modified Carman-Kozeny (2pMCK) relative permeability formulation with that of the industry standard, the Modified Brooks-Corey (MBC) formulation. The purpose is to show the strengths and weaknesses...
