“…Polymer flooding is considered as one of the efficient chemical enhanced oil recovery techniques especially in heavy oil reservoirs to improve sweep efficiency, however, it has specific limitations in actual oil fields operational performances. As a result, one of the chief aims of enhanced oil recovery (henceforth; EOR) techniques is to improve the sweep efficiency of the reservoirs after the polymer flooding processes, which is known as the conformance control [15][16][17][18][19][20][21][22][23].…”

Simultaneous utilization of surfactant and preformed particle gel (henceforth; PPG) flooding on the oil recovery enhancement has been widely investigated as a preferable enhanced oil recovery technique after the polymer flooding. In this paper, a numerical model is developed to simulate the profound impact of hybrid chemical enhanced oil recovery methods (PPG/polymer/surfactant) in sandstone reservoirs. Moreover, the gel particle conformance control is considered in the developed model after polymer flooding performances on the oil recovery enhancement. To validate the developed model, two sets of experimental field data from Daqing oil field (PPG conformance control after polymer flooding) and Shengli oil field (PPG-surfactant flooding after polymer flooding) are used to check the reliability of the model. Combination of preformed gel particles, polymers and surfactants due to the deformation, swelling, and physicochemical properties of gel particles can mobilize the trapped oil through the porous media to enhance oil recovery factor by blocking the high permeable channels. As a result, PPG conformance control plays an essential role in oil recovery enhancement. Furthermore, experimental data of PPG/polymer/surfactant flooding in the Shengli field and its comparison with the proposed model indicated that the model and experimental field data are in a good agreement. Consequently, the coupled model of surfactant and PPG flooding after polymer flooding performances has led to more recovery factor rather than the basic chemical recovery techniques.

“…As the swelling issue has reduced the permeability, shale micropores were blocked, and the channel was narrowed, which caused it to resist the movement of gas molecules . Another reason for this decrease might be related to the repulsive forces, which are happened between the adsorbed molecules and the surface coverages. , …”

“…One of the main challenges of petroleum industries is concerned about carbon dioxide emissions, which is produced from numerous operational performances from the atmosphere to reduce the pollution problem. − Carbon sequestration is widely utilized in production operations to reinject the produced gas in the reservoirs to enhance the oil recovery factor and virtually eliminate the vast expenditures of gas supply. Saline aquifers, depleted reservoirs, and gas hydrate reservoirs are considered as the potential reservoirs to carbon sequestration performances. − Gas transportation in shale layers is defined by the dual porosity or the triple porosity that needed to be numerically modeled to simulate the reservoir characteristics. ,− Although, previous models have considered the primary and secondary porosity in the dual porosity of the shale layers, which indicated that micropores had contained the primary porosity in the shale layers, macropores have consisted of natural fractures and cracks. − …”

Gas transportation is of significance, especially in carbon dioxide sequestration and successful performances of enhanced methane recovery from shale layers. Among the three primary transportation mechanisms for the gas phase in shale layers, diffusion is considered as the most important phenomenon. The main objective of this comprehensive study is to propose a mathematical model of unipore diffusion and modified unipore diffusion to consider the kinetic adsorption of methane and carbon dioxide for two different shale samples at different pressure ranges. To validate the accuracy of this model, experimental investigations such as methane kinetic adsorption at pressure ranges of 3.2−9.3 MPa and carbon dioxide kinetic adsorption at pressure ranges of 2.5−6.5 were performed to compare with the results of the proposed model. The kinetics adsorption analysis for methane indicated that the required time for the completion of fractional uptake process is about 4−13 min, whereas for the adsorption of carbon dioxide it takes approximately 5−17 min to reach 70% fractional uptake for both shale samples. Subsequently, the modified unipore diffusion model provides a good agreement for both carbon dioxide and methane kinetic adsorption from gas shale layers.

Electromagnetic wave is a viable means of introducing energy into reservoirs for the recovery of residual oil. However, previous studies have not considered the precise frequency of the electromagnetic (EM) wave. These studies focused on EM heating, not considering the efficiency dependence of EM transmitter and EM propagation on the EM properties of the medium. Thus, sandstone effective permittivity was experimentally measured, and electrical conductivity calculated for different saturation stages encountered in the nanofluid enhanced oil recovery process. The effective permittivity at the resonant frequency of the sandstone increased from 10.94 to 19.1 with a simultaneous frequency shift from 1.2 to 0.6 GHz due to the inclusion of magnetite nanofluid. This implies that the maximum transfer of EM energy for stimulation and activation of injected nanofluid can be achieved by irradiating the EM wave of this frequency within the reservoir for mobilization of the residual oil.
