Chapter 4 - Heat and mass transfer behavior between wellbores and reservoirs

Abstract

Abstract This chapter concerns the heat and mass transfer behavior of wellbores and heavy oil reservoirs. The non-Newtonian flow behavior of heavy crude oil in porous media is an important factor that affects heat and mass transfer. Through an experimental investigation into non-Newtonian flow behavior, a model for well productivity is developed and the productivities of vertical and horizontal wells in heavy oil reservoirs are discussed. Then, to predict the performance of thermal wells accurately, in the remaining parts of this chapter, the heat and mass transfer behavior of wellbores and reservoirs are experimentally and numerically studied. Furthermore, both pure steam injection processes and hybrid enhanced oil recovery processes are included. A mathematical model is also developed to match experimental data history.
