“…In the case of injection of biosurfactants and biopolymers for oil recovery or in the application of MEOR, VFAs are generated during various biotic and abiotic degradation processes. According to Vale et al [40], the mixture of biosurfactant and oil increased or decreased SRB activity depending on the surfactant concentration (high/low, respectively). Given that such organic carbon compounds are also incorporated into the cells as biomass, the dissolved organic carbon (DOC) content in the water is another useful parameter to assess the concentration of potentially bioavailable carbon [41].…”

The formation of hydrogen sulfide (H2S) in petroleum reservoirs by anaerobic microbial activity (through sulfate-reducing microorganisms, SRMs) is called biogenic souring of reservoirs and poses a risk in the petroleum industry as the compound is extremely toxic, flammable, and corrosive, causing devastating damage to reservoirs and associated surface facilities. In this paper, we present a workflow and the tools to assess biogenic souring from a pragmatic engineering perspective. The retention of H2S in the reservoir due to the reactions with iron-bearing rock minerals (e.g., siderite) is shown in a theoretical approach here and supported with literature data. Cases are provided for two fields under secondary (waterflooding) and tertiary flooding with microbial enhanced oil recovery (MEOR). The use of the Monte Carlo method as a numerical modeling tool to incorporate uncertainties in the measured physical/chemical/biochemical data is demonstrated as well. A list of studies conducted with different chemicals alone or in combination with various biocides to mitigate biogenic souring provides an overview of potential inhibitors as well as possible applications. Furthermore, the results of static and dynamic inhibition tests using molybdate are presented in more detail due to its promising mitigation ability. Finally, a three-step workflow for the risk assessment of biogenic souring and its possible mitigation is presented and discussed.

“…The amphiphilic property of surfactants enables their distribution at the oil-water interface. Moreover, the synergistic effect of MOA15 and SS-2306 promotes the adsorption of surfactants at the oil-water interface, which significantly reduces the critical micelle concentration (CMC) [32]. The lower CMC value favors the formation of micelles, increasing their number while reducing their size.…”

This work focuses on the development of a novel high-temperature microemulsion for enhanced oil recovery in tight oil reservoirs. Microemulsions are a type of mixture that has properties of both liquids and solids; they have shown significant potential for improving oil recovery through spontaneous imbibition. Herein, a high-temperature-tolerant lower-phase microemulsion using a microemulsion dilution method was developed. The properties and morphological characteristics of the microemulsion were evaluated and proposed a mechanism for enhanced spontaneous imbibition oil recovery using imbibition tests and CT scanning technology. The results of the study showed that the optimum concentration of the microemulsion was 0.2 wt% and that it had good thermal stability, small droplet size, lower interfacial tension, good wettability alteration ability, and minimum adsorption loss. The imbibition and CT experiments demonstrated that the reduction in oil/solid adhesion was due to the synergistic effect of IFT reduction and wettability alteration and the ability to increase the imbibition distance through a larger self-driving force. The study concludes that the solubilization coefficient and self-driving force were defined and calculated to quantitatively analyze the imbibition mechanisms and the results showed that the reduction in oil/solid adhesion was due to the synergistic effect of IFT reduction and wettability alteration and the ability to increase the imbibition distance through a larger self-driving force.

“…As a proven technology, water flooding is normally used after depletion of the natural reservoir driving forces. However, this method usually suffers from unfavorable sweep efficiency and displacement efficiency, which results in massive residual oil trapped in the formation. − Therefore, chemical enhanced oil recovery (EOR) techniques, which involve the use of polymers, surfactants, and alkalis, have been extensively applied after water flooding in mature oilfields. − …”

Two-dimensional nanosheets have attracted considerable attention as oil displacement agents due to their unique interfacial properties. However, the high cost limits the extensive application of conventional nanosheets in oilfields. In this study, an amphiphilic magnesium hydroxide (AMH) nanosheet was prepared through the surface modification of low-cost magnesium hydroxide nanosheets under mild conditions. The AMH demonstrates a twodimensional structure with 50−200 nm of plane size and 3.23−4.12 nm of thickness size. Scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared spectrometry (FTIR), and thermogravimetric analysis (TGA) were used to characterize the AMH. Due to the amphiphilic groups on the surface, AMH exhibited favorable interfacial activity and the oil−water interfacial tension (IFT) could be reduced by approximately two-thirds at a very low AMH concentration (100 mg/L). Meanwhile, an elastic film could be formed by the AMH at the oil−water interface. Furthermore, emulsions could be formed by AMH at an ultralow concentration (10 mg/L) and the oil-wet solid surface was transformed into intermediate-wet under the wettability alteration effect of AMH. Due to its amphiphilicity, 17.11% of additional oil could be recovered by AMH in a heterogeneous core with the permeability of 50/250/1000 mD. Considering the favorable ability in enhancing oil recovery and relatively low cost compared to conventional nanosheets, AMH has great potential in large-scale applications in oilfields as an oil displacement agent.
