“…Assessing the environmental impact especially in green projects is a necessary to build a common ground for competition with other alternatives in a growing sustainable green economy offering a plethora of alternatives and options. Due to ammonia being one of the most produced chemicals worldwide with already established facilities, [41][42][43] assessing the direct impacts like the resources consumption from water, energy and materials is already acknowledged. Although the process is green, analyzing the potential of any indirect pollutants and greenhouse gases (GHG) [44][45][46].…”

This study investigated the viability of green hydrogen as an essential component in the global energy transition. Despite intensified efforts prompted by the ongoing global energy crisis, impediments have arisen, notably in the area of green hydrogen storage techniques. The inherently hazardous nature of hydrogen gas, resembling an explosion when stored conventionally, presents a significant challenge. In response, this study proposed an environmentally friendly, carbon-neutral, and secure storage technique. The focus is on utilizing green hydrogen in the production of ammonia, serving as both a hydrogen carrier and energy storage medium on an industrial scale. The versatile application of green ammonia extended beyond storage, encompassing fertilizer production, refrigeration, and chemical manufacturing, all aligned with principles of sustainable development, green energy transition, and achieving net-zero carbon emissions. The comprehensive study involved the plant design, process flow diagrams, Aspen HYSYS simulation, plant layout, HAZOP study, and an in-depth economic analysis to evaluate feasibility and profitability. The Haber-Bosch simulated process encompassed the entire production line, starting from sustainably sourced hydrogen to the separation unit ensuring a green nitrogen source. Further optimization was achieved through a heat exchanger network utilizing Aspen Energy Analyzer. The study yielded a substantial ammonia production rate of 7058 kg/hr with an impressive conversion rate of nearly 85%, minimizing waste through the recycling of excess hydrogen within the process. The resultant liquid form of stored ammonia in the refrigeration loop facilitates convenient and safe storage of hydrogen.

Over time, oil consumption has increased along with a continuous demand for petroleum products that require finding ways to increase hydrocarbon production more economically and effectively. So, enhanced oil recovery technologies are believed to be very promising and will serve as a key to meeting the future energy demand. This paper aims to introduce an innovative method to boost the EOR by using two novel types of surfactants synthesized from sulfonamide derivatives. Types I and II surfactants were analyzed using Fourier transform infrared spectroscopy, and their characterization was further performed using 1H NMR and 13C NMR spectroscopy. Additionally, the evaluation of these surfactants included interfacial tension measurements at concentrations up to 0.9 wt %. The combination of types I and II surfactants with alkaline (NaOH) was also investigated by the measurements of interfacial tension. A series of coreflood and sandpack tests under high-salinity conditions were carried out to assess the effects of a surfactant alone and alkaline–surfactant as a combination on improving oil recovery. The rock wettability was evaluated using relative permeability saturation curves, and the oil displacement efficiency was determined using fractional flow curves. The coreflood results demonstrated that alkaline–surfactant flooding with the chemical formula 0.2 wt % surfactant type II plus 0.5 wt % NaOH achieved a higher oil recovery of 74% OOIP compared to surfactant flooding with the chemical formula 0.5 wt % surfactant type II (64% OOIP) and waterflooding (saline solution with a 35,000 ppm salinity: 48% OOIP). Moreover, the experimental results showed that under both core and sandpack flood conditions, there was a noticeable reduction in oil–water interfacial tension, a change in rock wettability to more water-wet, and higher efficiency of oil displacement when alkaline was added to the surfactant. Based on current research, the alkaline–surfactant formulation is strongly recommended for chemical flooding because of its high efficacy and relatively low cost.

“…In the Venezuelan Eocene, permeability was accurately predicted, and the hydraulic flow unit (HFU) was determined on sandstone reservoir rock. Attia et al 36 demonstrated that reservoir characterization is critical for secondary and enhanced oil recovery projects. The main goal of the research was to use reservoir characterization to identify productive zones and the barriers of the reservoir.…”

Electrical Tortuosity Index: A New Approach for Identifying Rock Typing to Enhance Reservoir Characterization Using Well-Log Data of Uncored Wells

et al. 2023

The world is gradually moving toward a severe energy crisis, with an ever-increasing demand for energy overstepping its supply. Therefore, the energy crisis in the world has shed important light on the need for enhanced oil recovery to provide an affordable energy supply. Inaccurate reservoir characterization may lead to the failure of enhanced oil recovery projects. Thus, the accurate establishment of reservoir characterization techniques is required to successfully plan and execute the enhanced oil recovery projects. The main objective of this research is to obtain an accurate approach that can be used to estimate rock types, flow zone indicators, permeability, tortuosity, and irreducible water saturation for uncored wells based on electrical rock properties that were obtained from only logging tools. The new technique is obtained by modifying the Resistivity Zone Index (RZI) equation that was presented by Shahat et al. by taking the tortuosity factor into consideration. When true formation resistivity (R t) and inverse porosity (1/Φ) are correlated on a log–log scale, unit slope parallel straight lines are produced, where each line represents a distinct electrical flow unit (EFU). Each line’s intercept with the y-axis at 1/Φ = 1 yields a unique parameter specified as the Electrical Tortuosity Index (ETI). The proposed approach was validated successfully by testing it on log data from 21 logged wells and comparing it to the Amaefule technique, which was applied to 1135 core samples taken from the same reservoir. Electrical Tortuosity Index (ETI) values show marked accuracy for representing reservoir compared with Flow Zone Indicator (FZI) values obtained by the Amaefule technique and Resistivity Zone Index (RZI) values obtained by the Shahat et al. technique, with correlation coefficients of determination (R 2) values equal to 0.98 and 0.99, respectively. Hence, by using the new technique, the Flow Zone Indicator, permeability, tortuosity, and irreducible water saturation were estimated and then compared with the obtained results from the core analysis, which showed a great match with the R 2-values of 0.98, 0.96, 0.98, and 0.99, respectively.
