“…37 Slug volume for Sandstone-1 drops from 2.45 PV (CW) to 1.71 PV (SCW) and for Sandstone-2 from 1.87 PV (CW) to 0.71 PV (SCW) because of in situ foam formation and IFT reduction. 35,64 Improved sweep efficiency is the consequence of the interaction of decreased interfacial tension, emulsification, 78 Introducing nanoparticles with different surface energies modifies a material's overall surface energy possible. Hydrophilic nanoparticles (ZnO nanoparticles) increase the surface energy and make the material more wettable toward water.…”

“…To address these challenges, alternative foam stabilizing agents, such as nanoparticles and polymers, are being explored to ameliorate the stability and foam effectiveness for enhanced oil recovery applications. Chen 35 and Mosavat 45 have researched how carbonated water affects oil recovery efficiency. It was determined that the oil recovery from the sandstone cores improved once CO 2 was added to the solution.…”

“…Carbonated water injection is an alternate method to address issues in prior studies, such as high mobility ratio, channeling, gravity segregation, and viscous fingering. Carbonated water injection (CWI) involves absorbing CO 2 in water under precise pressure settings and injecting the mixture into a reservoir. − This process can be reverted and decomposed into carbon dioxide and water as the pressure subsides. Furthermore, carbonic acid produced during the generation of carbonated water will produce both reversible carbonate and bicarbonate ions, resulting in water and CO 2 . H 2 normalO + CO 2 ↔ H 2 CO 3 H 2 CO 3 ↔ H + + HCO 3 − HCO 3 − ↔ H + + HCO 3 2 − When CaCO 3 , MgCO 3 , and FeCO 3 are present in the rock, they make water-soluble bicarbonates, followed by reaction .…”

The enhanced oil recovery techniques are everevolving to cater to the need for increased oil demand. To improve the EOR efficiency, the new approach combines chemical additives such as nanoparticles and surfactants with carbonated water to address the issues of reduced mobility control, gravity segregation, and early breakout encountered in CO 2 flooding. The in situgenerated CO 2 foams are unstable structures depending upon additional additives to strengthen their lamella and improve their stability, which ZnO nanoparticles (NPs) provide in the current study. This research investigates the synergistic impact of sodium dodecyl sulfate (SDS) and ZnO NPs on the CO 2 foam generated from carbonated water. The carbonated water flooding tests were conducted using optimal SDS and ZnO concentrations of 2500 ppm and 0.01 wt %, respectively. The processes underlying the synergistic action of SDS and ZnO are altering nanoparticle adsorption sites on the CO 2 and liquid interface, enhancing the CO 2 foam's interfacial characteristics, and lowering its liquid discharge and coarsening. Further, four flooding procedures were utilized on two sandstone cores with contrasting petrophysical characteristics to study the effect of foam-assisted carbonated water flooding. The oil recovery was influenced and increased by SDS and ZnO NPs. The outcomes show that CO 2 foam flooding (nanoparticles included) generated using carbonated slug illustrates effective conformance control and enhances oil recovery from sandstone. It has been observed that nanosurfactant-added carbonated slug flooding gives a 50.00% and 194.72% recovery enhancement compared to regular carbonated water flooding for sandstone-1 and sandstone-2, respectively.

Modeling Results for the Real Horizontal Heavy-Oil-Production Well of Mechanical Solids

Recently, more and more new oil fields entering commercial production are complicated by the content of high-viscosity products, which are located at relatively shallow depths. For the rational development of such fields, a network of horizontal wells is used. A special feature of these objects is a weakly cemented reservoir, which leads to significant sand occurrence during well operation. At the same time, the removal of mechanical impurities cannot be avoided even when using complex measures, including the use of various filters. There are quite a few methods describing the behavior of mechanical impurities in gas–liquid flows. The purpose of the work was to analyze the removal of mechanical impurity particles from horizontal wells with high-viscosity oil. A model of a typical well in the OLGA software was created, and data on the types of particle removal were obtained. As a result of calculations, the quality of removal for different diameters of mechanical impurities was determined, and the dependence of the critical diameter on the well flow rate was constructed.

“…It is possible to increase the oil displacement rate while maintaining profitable production rates, both by exposing the rock matrix to acid compositions [10], and by treating highly permeable fractured channels with water shut-off compositions [11]. However, despite the fact that there are many technologies and chemicals to combat well water flooding [12][13][14][15], most of them are designed for pore reservoir conditions [16][17][18] and their use is not always effective in environments with double porosity, in which the water shut-off material must penetrate water-saturated fractures without plugging the low-permeability matrix of the productive formation [19][20][21].…”

Technology for Improving the Efficiency of Fractured Reservoir Development Using Gel-Forming Compositions

Increasing the field development efficiency of fractured reservoirs is a contemporary issue. This paper presents fundamental and exploratory research results in this field using modern high-tech experimental equipment from the “Arctic” Scientific Centre at the Saint Petersburg Mining University. Oil reserves in fractured reservoirs are enormous; however, they are classified as hard-to-recover. The before-mentioned reservoirs require a specific approach when selecting technologies to improve the efficiency of their development. In this paper, as a solution to the problem under discussion, we propose the use of a physicochemical method of developing fractured reservoirs based on the injection of a water shut-off agent to exclude highly permeable water-conducting fractures from the drainage process. This technology makes it possible to effectively include and develop previously undrained reservoir areas by directly controlling their filtration properties with the use of new highly efficient and ecologically safe chemical reagents and process fluids.
