“…It is noted that this research did not consider changes in the thermal conductivity of the rock with temperature. In reality, the thermal conductivity of the rock can change because of the heating process, which can affect the rate of kerogen decomposition [41].…”

In situ heat injection is a suitable technique for extracting shale oil from reservoirs with high organic matter content but insufficient thermal maturation. To optimize the stimulation process and to avoid unnecessary energy consumption, understanding the thermal process and the effects of thermal parameters is crucial. This research employs a self-developed simulator to build a 2D numerical model of the in situ conversion process of kerogen with electric heaters. A benchmark model is first established to determine the effects of heat injection on crude oil production and kerogen decomposition. Subsequently, this study analyzes the evolution of shale oil within the reservoir, identifying the role of thermal and physical properties in crude oil production and kerogen decomposition during the stimulation treatment. A sensitivity analysis of the thermal properties of the reservoir is also carried out, which allows for defining the role of the thermal conductivity of the rock during the stimulation process. Finally, it is observed that, when using the injection at a constant power, the injection time to achieve a suitable large rate of decomposition is shorter than at a constant temperature—consequently, it has a higher economic advantage.

“…The thermal properties of most rocks are known to be dependent on the bulk density, porosity, grain (crystal) size and shape, cementation, formation pressure, temperature, anisotropy, mineral composition, and the nature of saturating fluids [13][14][15][16][17][18][19][20]. The thermal conductivity of consolidated rocks is known to be predominantly controlled by the composition of rock solids and saturating fluid, and porosity [18].…”

“…Usually, the SRM method's application through β-SiC foam bed improves the heat transfer and mass transfer due to high porosity and surface area of the β-SiC foam (Vanhaecke et al, 2012). Mass, energy and momentum balance's equations for the gas phase as well as mass, energy and momentum balance's equations to the solid phase are described through mathematical models (Ma et al, 2016;Hussain et al, 2006). Here, a Non-isothermal Pseudo-Homogeneous Mathematical (NIPHM) model is used to model the SRM method in the TPB reformer.…”

Thermochemical Packed-Bed (TPB) reformer has been substantially studiedin the past years as a promising equipment to investigate thethermochemical conversion of methane (CH4). This work has as mainobjective a theoretical modelling to describe the process variables of SteamReforming of Methane (SRM) method in the TPB reformer. The TPBreformer is filled with β-SiC open-cell foam where the thermochemicalconversion of CH4 is carried out. The model variables describe the specificaims of work and these objectives can be identified from each equation ofthe developed mathematical model. This work has been proposed to studytwo specific aims as (i) the effective thermal conductivity's effect of thesolid phase (λs,eff.) and (ii) molar flows of chemical components. Theendothermic reaction temperature's profiles are notably increased as thenumeral value of λs,eff. is raised. The Steam Reforming of Methane (SRM)method is suggested to improve the Production Rate (PR) of H2 regardingthe PR of CO. As results, the PR of H2 is of 29.48% while the PR of CO isof 2.76%.
