“…The results of this study are comparable with those reported by Shaker et al (2014), using different sampling strategies, stratigraphic horizons, and locations for these oil shale deposits. However, the study oil shale has a relatively loweryield of shale oil and gas, compared to other deposits in Jordan and the Dead Sea area, US Green River, and the Estonia (up to 250 l/ton shale oil yield), (e.g., Shirav (Schwartz) and Ginzburg, 1983;Jaber et al, 2011;Speight, 2012;Alnawafleh and Fraige, 2015).…”

“…The average content of spent shale in the analyzed samples ranges between 81.7% and 92.2% by weight with an average of 89.8%, as shown in Table 1. Spent shale is the residual ash of the pyrolysis process, which is considered here mainly as a high carbonate-base spent shale (e.g., Jaber et al, 2011). The spent shale content is inversely related to the oil (Fig.…”

“…Oil yield is a crucial parameter to determine the feasibility of an oil shale deposit to be exploited as a source of synthetic oil production via a retorting process (Jaber et al, 2011). Several sedimentological, bio-stratigraphic, organic geochemical, and mineralogical studies have been carried out on the Egyptian oil shale (e.g., Tröger, 1984;Ganz et al, 1987;Hendriks et al, 1987;Glenn and Arthur, 1990;El-Kammar 1993;Tantawy et al, 2001;Baioumy and Ismaeil, 2010;El-Shafeiy, 2012;and others).…”

Oil shales are source rocks of low to moderate maturity, which are considered as a potential deposit for future hydrocarbon generation. In Egypt, the epicontinental Cretaceous-Paleogene sequence is a part of a Middle East belt of oil shale deposits. The belt, in the Egyptian territories, is trending east-west and extending from the Quseir-Safaga district along the Red Sea to the Kharga-Dakhla oases in the Western Desert, passing through the Nile Valley between Idfu and Qena. These oil shales are constrained to the Duwi-Dakhla formations in ascending order. In this study, the Fischer assay technique is used to get oil yield for 37 selected oil shale core samples from seven localities along the Red Sea to come up with an evaluation. The average oil yield values of Abu Shegela, M. Rabah, Sodmine, and Um El-Huweitat areas are acceptable from the economic and processing points of view for the exploitation step. Raw-mix designs are necessary for high-yield and low-medium-yield strata for future exploitation of these shales. We propose the In-Capsule Retorting method to extract oil from the study oil shales, because of its inexpensive and environment-friendly characters.

“…However, there are vast proven reserves of oil shale of more than 70 billion tons, within an average content of shale oil, i.e. liquid fuel, yield between 5-8 billion ton [1,2]. In addition, Jordan has abundant supplies of RE sources: high average daily solar radiation of between 5-7 kWh m -2 day, and acceptable wind speed (6-8 m/s) to generate electricity [3].…”

This paper aims to present energy supply, demand and policy reforms, in Jordan, that had helped in transforming renewable energy schemes into bankable projects. The current study focuses on implemented and planned renewable projects and its investment as a case study aiming to identify impacts on economy and environment, with emphasis on the power sector. In order to attract private sector participation in the development of such projects, the government developed and enacted a new system of direct proposals as well as needed regulations. This resulted in the construction of more than 1000 MWe of renewable energy and awarding about 1500 MWe to be completed until end of 2024. According to the adopted methodology, in this study, the calculated avoided GHG emissions resulting from the completion of these projects, during the study period from 2016 and up to 2025, are significant. The net anticipated accumulated reduction of GHG emission over this period exceeded 16 million ton of CO2 eq. The solar PV sharing ratio being the highest, i.e. 45% of total accumulated reduction, followed by wind, about 24%, and direct applications of renewables by 28%. Such figure may increase in the future depending on the completed capacity and would touch 20 million ton by 2025, when all planned projects are completed.

Jordan's energy sector faces significant challenges due to rising fuel prices, making the exploration of local energy resources crucial. The abundant oil shale deposits in Wadi Thamad present a promising opportunity. Since Wadi Thamad oil shale has never been studied before, this research focuses on the Wadi Thamad basin near Madaba, Jordan, aiming to comprehensively characterize its oil shale using advanced analytical techniques. Using X‐ray diffraction, Fourier transform infrared spectroscopy, X‐ray fluorescence, scanning electron microscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry, this study assesses the mineralogical, chemical, and thermal properties of Wadi Thamad oil shale. The findings reveal calcite and quartz as the primary minerals, with significant aliphatic, CO2, hydroxyl, and carboxyl groups. Elemental analysis highlights essential oxides, such as CaO and SiO2. Fischer assay results indicate an oil content of 5.3–10.1 wt%, a gross‐calorific value of 4.56–7.69 MJ/kg, and a sulfur content of 1.77–2.10 wt%. The peak pyrolysis temperature is 432.4°C from TGA. This research's novelty lies in its comprehensive approach to characterizing the underexplored Wadi Thamad oil shale basin. The findings enhance the understanding of Wadi Thamad's geological composition and underscore its potential as a local energy resource, contributing valuable data to Jordan's energy portfolio and offering economic benefits.
