TAILIEUCHUNG - Pore size distribution in simulation of mass transport in porous media: A case study in reservoir analysis

The modeling and numerical simulation of mass transport in porous media is discussed in this work by using the so-called pore size distribution for computing transport properties. The pore-size distribution is a property of the pore structure of a porous medium. This can be used to estimate the different transport properties, amongst other, the permeability. | Vietnam Journal of Science and Technology 56 (2A) (2018) 24-30 PORE SIZE DISTRIBUTION IN SIMULATION OF MASS TRANSPORT IN POROUS MEDIA: A CASE STUDY IN RESERVOIR ANALYSIS Vu Hong Thai*, Vu Dinh Tien School of Chemical Technology, HUST, 1 Dai Co Viet Road, Ha Noi Department of Chemical Process Equipment, HUST, 1 Dai Co Viet Road, Ha Noi * Email: Received: 2 April, 2018; Accepted for publication: 13 May 2018 ABSTRACT The modeling and numerical simulation of mass transport in porous media is discussed in this work by using the so-called pore size distribution for computing transport properties. The pore-size distribution is a property of the pore structure of a porous medium. This can be used to estimate the different transport properties, amongst other, the permeability. By starting with a formula for the absolute permeability, the simulation of water and oil transport in reservoirs is considered by solving mass conservation equations with the help of the control volume method. The influence of the pore size distribution on the transport behavior is discussed to demonstrate the adequacy of the use of pore size distribution in studying the behavior of reservoirs. Keywords: pore size distribution, mass transfer, reservoir, control volume method, numerical simulation. 1. INTRODUCTION The modeling and numerical simulation of mass transport in porous media is a topic of great interest in different fields of engineering and have attracted the attention of research institutions for decades. The mass transport of liquids in general and of water and oil in particular finds its application not only in civil engineering, chemical engineering, food processing and pharmaceuticals but also in cutting edge technologies like in electronic packaging [1-9]. Many works were realized to study the behavior of porous media under various transport conditions and for different fluids. Amongst these, a huge amount of effort was put on the modelling and simulation of
