Heat Dissipation Modeling of <i>In-Situ</i> Conversion Process of Oil Shale

Abstract

In-situ conversion of process of oil shale has been technically proven as a pilot field project. Gradually heating the reservoir by using subsurface electric heaters converts the oil shale reservoir kerogen into oil, gas and other producible components. This process also enhances the internal energy of the porous media as well as the subsurface fluid. Heat is transmitted in the reservoir within each fluid by different processes i.e., due to the flow of fluid called advective process, and due to molecular diffusion where dispersive and diffusive processes take place. Heat transfer through conduction and convection mechanisms in the porous media are modeled mathematically and numerically incorporating the advective, dispersive and diffusive processes in the reservoir. The results show the production of oil and gas as a result of conversion of kerogen due to modeled heat dissipation.

Application of 3D Reservoir Geological Model on Es1 Formation, Block Nv32, Shenvsi Oilfield, China

“…Also, when the reservoir model of Es1 formation was completed, the structure model and property model were used to calculate oil reserve in term of Stock Tank Oil Initial in Place (STOIIP). The Es1 formation was estimated by applying the equation [9]- [17]. Table 3 shows the volumetric outcome result after modeling has been done.…”
