“…To provide sustainable oil demand in numerous industries, it is important to increase the recoverable oil from the oil reserves. Drilling the new exploration wells or enhanced oil recovery methods considered as the preferable ways to produce more oil volume [1][2][3][4][5][6][7]. Chemical recovery techniques revolutionize the way petroleum industries operate the full range of reservoir management and how to optimize each method to eliminate unnecessary expenditures virtually [8][9][10][11][12][13][14].…”

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.

A liquid droplet can hover over a solid surface that is heated above the Leidenfrost point (LFP), at which an insulating vapor layer is formed that acts as a heat transfer barrier. Recent studies have reported that hierarchical micro- and nanoscale textures provide high wettability and significant LFP enhancement. However, such textures are often difficult and expensive to fabricate. Therefore, this study aimed to experimentally demonstrate LFP enhancement through the use of low-cost hierarchical textures. Surface textures were fabricated by coating SiO2 nanoparticles on stainless steel wire meshes. The droplet lifetime method was used to determine the LFP in a temperature range of 200 °C–490 °C. High-speed imaging (4000–23,000 fps) was performed for visualizing the impact behavior of a droplet. The LFP value of the nanocoated mesh surface was found to be greater than 490 °C. This enhanced LFP was 178 °C higher than that of a stainless steel surface and 38 °C higher than that of a single-layer textured surface. Furthermore, with respect to the LFP enhancement, the explosive impact behavior of a droplet can be observed on nanocoated mesh surfaces.

“…Synthetic polymers such as polyacrylamide (PAM), hydrolyzed polyacrylamide (HPAM), xanthan, biologic polysaccharide and some of the natural polymers like hydroxyl ethyl cellulose (HEC), sodium carboxyl-methyl cellulose and guar gum that are modified in specific processes are the most ubiquitous polymers in petroleum industries. The advantages of these polymers are as follows: PAM (polyacrylamide): Due to its high value of molecular weight (approximately more than 10 6 gr./mole) that usually performed as a thickening agent for the aqueous solutions. Moreover, PAM has its stable properties at the temperature of 90 • C at the normal salinity and at the salinity of seawater; the temperature is set up at 62 • C Hence, it is worthwhile that this type of polymer would be restricted on the on-shore performances [19].…”

“…Among a wide range of chemical EOR techniques, polymer flooding has been considered to be an efficient recovery technique, especially for heavy oil reservoirs. In this technique, polymer molecules are added to water for the purpose of mobility reduction to increase water viscosity than oil in place [ 4 , 5 , 6 , 7 , 8 ]. Therefore, oil could mobilize easier than water, which caused to enhance oil production rate.…”

Among a wide range of enhanced oil-recovery techniques, polymer flooding has been selected by petroleum industries due to the simplicity and lower cost of operational performances. The reason for this selection is due to the mobility-reduction of the water phase, facilitating the forward-movement of oil. The objective of this comprehensive study is to develop a mathematical model for simultaneous injection of polymer-assisted nanoparticles migration to calculate an oil-recovery factor. Then, a sensitivity analysis is provided to consider the significant influence of formation rheological characteristics as type curves. To achieve this, we concentrated on the driving mathematical equations for the recovery factor and compare each parameter significantly to nurture the differences explicitly. Consequently, due to the results of this extensive study, it is evident that a higher value of mobility ratio, higher polymer concentration and higher formation-damage coefficient leads to a higher recovery factor. The reason for this is that the external filter cake is being made in this period and the subsequent injection of polymer solution administered a higher sweep efficiency and higher recovery factor.
