“…In order to investigate the effectiveness of noninogenic surfactants, five samples of each surfactant were prepared in 0.05, 0.1, 0.25, 0.5 and 1 wt% concentrations. Next, the study was carried out on a tensiometer, the principle of which is schematically shown in Figure 2 [17]. First, the effect of surfactant on wettability was evaluated, the study was conducted as follows:…”

The growing need of the population for energy and hydrocarbon fuel, leads to an accelerated pace of development of the oil industry. In this regard, there is a need to develop new or renew the development of old oil fields. Among a range of existing EOR methods, the use of surfactants is considered as one of the main options aimed for both raising oil production and improving oil recovery. In this work, a study was carried out to define the characteristics and criteria for selection of an effective surfactants which are used in the tertiary scheme of recovery (IOR or EOR) from reservoir formations and especually during Enhanced Oil Recovery (EOR) flooding system. Three cationic surfactants with specific trade names were used in this study. It has been revealed that addition of surfactants positively affects inhibition of clay issues even in a more efficient manner than potassium chloride as one of the most widespread used clay inhibitors. At the end, a comprehensive discussion and suggestions are provided on the importance of temperature, concentration and bottom-hole conditions that affect selection of an optimum surfactant.

Flue gas injection into subsurface formations has emerged as a promising approach for enhanced oil and gas recovery, as well as geological carbon sequestration. Extensive numerical and experimental studies have been conducted to explore the effectiveness of flue gas injection. In this comprehensive review, we organize an overview of the main sources of flue gas and their compositions across various industries. We examine different flue gas injection types coupled with enhanced oil and gas recovery methods. Additionally, we summarize the evaluation methods for gas storage capacity found in the literature, which can guide the development of advanced theoretical models and simulation tools. The impact of flue gas injection patterns on recovery factor is analyzed, encompassing both continuous and cyclic flue gas injection strategies. Furthermore, we investigate the effects of fracture and matrix permeability during flue gas injection, as well as the impact of flue gas composition on oil recovery. Moreover, we discuss the intricate geochemical reactions that occur between flue gas compositions, formation brine, and rock. These reactions can lead to significant changes in the chemical equilibrium, affecting the overall process. Recent advancements in numeric modeling techniques are reviewed, including the application of various simulators such as Eclipse, CMG, Petrel, TOUGH2 V2, PHREEQC, and COMSOL to simulate flue gas injection scenarios. These models offer valuable insights by considering the main factors and mechanisms involved. Finally, we address the existing knowledge gaps and provide recommendations for future studies in this field. By further investigating these areas, we can enhance our understanding of flue gas injection processes and optimize their implementation for enhanced gas and oil recovery and carbon sequestration.

Cryogenic LN2 fracturing is one of the environmentally friendly waterless fracturing technologies that promote the fracture complexity of shale gas reservoir. The water-ice phase transition under freezing condition causes frost heave in saturated shale. The effect of moisture in shale should be taken into account during cryogenic damage process. Therefore, the differences of cracking characteristics between dry and saturated shales were studied in this paper. A laboratory triaxial and high temperature fracturing system was developed for nitrogen fracturing dry and saturated shale after LN2 injection. The influence of moisture on breakdown pressure was studied under different confining pressures (3 MPa, 6 MPa, 9 MPa, and 12 MPa) and bedding directions (parallel bedding and vertical bedding). The experimental results demonstrated that when the confining pressure increased from 3 MPa to 12 MPa, the breakdown pressure of dry parallel bedding after LN2 preconditioning decreased 7.12 MPa, 6.06 MPa, 4.58 MPa, and 3.11 MPa, respectively. Therefore, LN2 preconditioning could damage shale resulting in a lower breakdown pressure, but the effect of cryogenic damage decreased with the confining pressure increasing. The moisture in shale had little impact on nitrogen fracturing without LN2 injection because the breakdown pressure difference between dry and saturated shales was small. However, the breakdown pressure of saturated shale after LN2 preconditioning was always lower than that of dry shale. The breakdown pressure of saturated parallel bedding shale after LN2 injection decreased 8.62 MPa, 7.67 MPa, 6.08 MPa, and 4.63 MPa, respectively, with the confining pressure increasing from 3 MPa to 12 MPa. The breakdown pressure difference between dry and saturated shales was impacted by the migration of unfrozen water and frost heave. In addition, the extent of cryogenic damage varied substantially between different bedding directions. When the confining pressure was 3 MPa, the breakdown pressure of saturated parallel bedding shale reduced by 69.18% after LN2 preconditioning, but that of saturated vertical bedding shale only decreased by 22.49%. The tensile strength of shale had a greater influence on the breakdown pressure. According to the Brazilian disc test results, the tensile strength of matrix was much higher than that of bedding planes. As a result, it is useful to wet the shale in order to reduce the breakdown pressure. The fracturing direction of horizontal drilling should be consistent with the bedding direction for better cryogenic fracturing effect.
