B.Tech IV Year II Semester (R16)
The objective of this course is to introduce the basic theory and
computational techniques for modeling multiphase flow in sub-surface porous media, especially applied to petroleum reservoir simulation. The students will also study conceptual and mathematical models that represent simplified scenario of petroleum reservoir.
The students would gain knowledge on core sample characterization and
properties measurement. They would get a feeling for time-scales of porous media flow, fluid pressure and chemical diffusion. They would understand the natural variability of porous media and the scale-dependence of flow properties. They know about pattern formation in porous media flow and about key coarsening instabilities like thermal or chemical convection etc.
Introduction: Phases and porous media: Grain and pore size distribution- the concept of saturation – the concept of pressure – surface tension considerations – concept of concentration.
Mass conservation Equation: Micro scale mass conservation – Integral form of mass conservation – Integral Theorems- point form of mass conservation – The macro scale perspective – The averaging theorem – Macro Scale mass Conservation – Applications
Flow Equations: Darcy’s Experiments, fluid properties – Equation of state for fluids- Hydraulic potential – single phase fluid flow- Two phase immiscible flow- The Buckley- Livertt Analysis.
Mass Transport Equations: Velocity in the species transport equations – Closure relations for the dispersion vector– Chemical Reaction Rate - Initial and boundary conditions.
Simulation:1-D simulation of Air-Water Flow- 1-D Simulation of DNAPL water flow – 2-D simulation of DNAPL Water flow – Simulation of multi phase flow and transport – 2-D single phase flow and transport – 3-D single phase flow and Transport– 2-D Three phase flow
