... and Convection A final variation of electro-thermal heating introduces convective heat transfer by injecting water at the electrode [7]. Electro-thermal with Conduction and Convection is the third configuration shown in Figure 2. Again, heat is created in the reservoir as electrical current passes through...

... transfer phenomena at an injection well. Four thermal phenomena to construct numerical modeling were considered in order to predict CO2 temperature and pressure at the bottom hole. 1) Natural convection in annulus: Convection flow in the annulus filled with N2 or H2O increases heat transfer from tubing...

... beneath and a gravitationally unstable diffusive boundary layer is induced, which may lead to natural convection. In this paper, a mathematical model for the diffusive boundary layer in the CO2-oil contact region is developed; and, the possibility of convective mixing is examined using linear stability...

However, the pressure distribution exhibits an abnormally high pressure build-up resulting from the relative thermal expansion of in-situ bitumen in the region where the temperature is slightly higher than...

Calculating the rate and direction of steam chamber movement, the in situ thermal diffusivity and the role of conduction and convection in heat transfer provide a foundation for understanding the interaction between the SAGD recovery process and the reservoir...
