Fractional Yield, Extract Composition and Variability from Jordanian Oil Shales  [PDF]
Hani M. Alnawafleh, Feras Y. Fraige, Khalid E. Tarawneh, Ibrahim A. Sarairahc, Laila A. Al-Khatib
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2016, DOI: 10.4236/jasmi.2016.63007
Abstract: Surface and subsurface oil shale (OS) rocks in Jordan have potential economic value for the country and still unutilized. This research paper focuses on central and southern OS deposits in Jordan. Brief characterization of four OS deposits is presented. Size distribution test and elemental analysis were performed. Shale oil was extracted via three solvation methods: Soxhlet extraction, extraction via mixing and stirring, and lastly super-critical fluid extraction. Major shale oil fractions were obtained from extract fractionation on chromatographic column. The nuclear magnetic resonance spectroscopy technique was used to study qualitatively the fractional composition of OS extract. Results show that all studied OS deposits have quite similar trend in their particle size distribution and their elemental composition. These OS deposits are found to be varying in their solvation behavior, fractional yield, and shale oil composition. Highest yield is obtained from polar solvents. The OS extraction via solvation processes is promising under certain extraction conditions such as super-critical conditions. The solvation variability of Jordanian OS indicates that different extraction techniques suit different OS deposits. Such variability should be considered in any future extraction options.

Hani M. Alnawafleh, Khalid E. Tarawneh, Hani N. Khoury, Nafeth A. Abdelhadi, Osama Y. Shakkoury, Reyad A. Dwairi, Mazen N. Amaireh
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.510061
Abstract: This work represents the first detailed study of an oil shale (OS) section from the Upper Campanian Amman Silicified Limestone (ASL) Formation in south-western part of Jordan. More than five meters of oil shale have been recorded. Using the petrography and geochemistry, this study aims to focus on such non-conventional types of oil shale rocks in Jordan and to shed some light on their composition and formational environment. Unlike oil shale from Maastrichtian to early Tertiary, this type of oil shale is highly dolomitized. The dolomite is diagenetic in origin. This oil shale type contains considerable amount of OM and remarkably enriched in some trace elements and shows quite low sulfur content. Results suggest that the formation of dolomite appears to be limited by the rate of organic matter oxidation.
Geologic and economic potentials of minerals and industrial rocks in Jordan  [PDF]
Hani Alnawafleh, Khalid Tarawneh, Rami Alrawashdeh
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.56092
Abstract:

This work discusses status of the geologic and economic potentials of minerals and industrial rocks in Jordan. The major mineral resources are presented in details and the paper is designed to cover the lack of published data in this field. Geologically, the structural framework of Jordan is controlled largely by Arabian Nubian Shield in the south, block—faulted areas in the east, upwarping in north and east, and Wadi Araba-Dead Sea Transform Fault in the western part. The geologic environments include Precambrian crystalline basement (Late Proterozoic) of Arabian Nubian Shield (ANS) that is composed of igneous and metamorphic rocks at south-western part. Paleozoic rocks at southern and southeastern part consist of clastic minerals which are dominated by sandstone, whereas Mesozoic sedimentary rocks are widespread throughout southwestern, northern to southeastern parts of the country. They mainly consist of major industrial rocks and minerals such as phosphate, oil shale, limestone, dolomite, chalk, marble, gypsum, diatomite and tripoli. Cenozoic Era is composed of sedimentary and volcanic rocks in different parts of Jordan. There are more than twenty nonmetallic minerals and four main metallic deposits within the various geologic environments. This paper summarizes their distribution, chemical and mineralogical characteristics, in addition to their production statistics.

Abstract: Jordan has huge limestone reserves which are used to produce aggregates for construction purposes. These reserves are very important economic sectors in Jordan, but many of these reserves belong to quarries that are located near urban territories. The mining operation type is mainly open cast and this activity has fugitive dust sources that contribute to increasing air quality levels in the urban areas around the quarries. Many of the biggest quarries in Jordan surrounded with urban territories are located in the north of Jordan district Irbid (Sammad area). Due to the quarrying activities, especially those from limestone quarrying (e.g. drilling and blasting, excavation, and transportation) in North Irbid, it is noticed that there is a primary source of an increased level of particulate matter (PM10), which leads to a potential representing pollution to the surrounding areas. PM consists of very small liquid and solid particles floating in the air with a diameter less than 10 microns that are subject to be inhaled into the deepest parts of the lung, and subsequently cause harmful health problems for population. PM10 dust re-suspension factors of the surrounding areas near the limestone quarries close to Sammad area/Irbid province were measured for different seasons at two station areas: Shatana and Rahma. To obtain data and assessment of the impact from this source, measurements included PM10 mass, particle size distributions, wind speed, and wind direction. The results showed that PM10 concentrations could be as high as 130 μg/m3, and that most of the airborne PM was in the coarse fraction. The results revealed that in winter season during the workday, the concentration of PM10 was equal to or below the Jordanian standard, while in summer season during workday the concentration of PM10 was over the Jordanian standard. However, forward trajectories showed that pollutants were attributed to the mining activities inside the quarries and distributed outside the mining area surrounding with urban territories.
Geochemistry and Organic Petrography of Jordanian Sultani Oil Shale  [PDF]

Open Journal of Geology (OJG) , 2016, DOI: 10.4236/ojg.2016.610089
Abstract: The Sultani oil shale (OS) deposit is considered as a major fossil fuel source in Jordan. Applying various petrographic and geochemical techniques, this paper aims to study the Sultani OS geochemical and organic petrographic features. Results show that Sultani OS is a bituminous limestone consisting of very fine-grained matrix with rippled micro-laminated texture and muddy material of cryptocrystalline micrite. The rock is rich in Cretaceous microfossil shells filled in organic matter (OM). The fillingOMis bitumen of the migrabitumen type. TheOMcontent reaches up to 17 wt.% with high oil-yielding capacity (up to 12 wt.%). High TOC values suggest that the Sultani OS has a very good source rock potential. Organic petrography shows lowOMmaturity level and reveals two varieties of vitrinite, namely primary and oxidized vitrinite. The latter is derived from terrestrial plant tissues. Additionally, liptinite macerals including alginite and to a lesser extent cutinite, also participate. Various diagenetic features such as pyrite replacement and bitumen thermal alteration have been recorded. Results suggest that Sultani OS is a marinite formed under marine conditions with limited contribution of terrestrialOMinput.

Hroon Tarawneh
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.411076
Abstract: Current literature on software project management indicates that the majority of software projects either are considered a failure or challenged. These projects are characterized by exceeding budget, exceeding time, and failing to meet customer expectations. The fact that most projects fail highlights the need for research regarding the factors that lead to software project success or failure. This paper presents a theoretical framework for software project success. Based on deep analysis of current literature on software success factors, a theoretical framework is formulating. The suggested framework shows factors that have to be carefully considered in order to achieve software project success. The factors included in the framework are dividing into four categories: organizational factors, technical factors, people factors, and culture factors. The suggested framework is new in the sense that it includes many factors that are not founding together in any of the previous similar frameworks.

Abstract: Jordan’s mining sector is considered the cornerstone to the Jordanian economy. It plays a vital role in growth of many other important sectors in the economy and contributes to the Jordan’s standard of living. The mining industry in Jordan is dominated by the production of phosphate, potash, building and decoration stones, glass sand and other nonmetallic resources. Recently, Jordan has been ranked as the sixth largest producer and the second largest exporter of phosphate, the fourth largest producer and the second largest exporter of potash, and has the 5th largest oil-shale reserves in the world. Also, Jordan has sustainable amounts of uranium around 3% of the world resources. The main objective of this research is to focus on the present status of mining industry in Jordan with the aim to emphasis the most important industries, and its effect on the economy of Jordan in order to generate new wealth depends on its mineral endowment. A literature review has been carried out by reviewing the most published articles and the publicly available reports published by various Jordanian Institutions as well as from the private sector. The author reveals that there are many positive outlooks which are looming with an increasing domestic added value along with investing in other areas, such as feldspar, clays, travertine, gypsum, zirconium, uranium, copper and rare earth elements (REE). This requires activating the exploitation of many other untapped mineral resources in the country to achieve a progress that works for meeting the global great demands worldwide. In this context, successive governments have put effort into policies that promote and facilitate investment in the mining sector in Jordan. A comprehensive outlook of the mining sector in Jordan has been discussed in this article. The author also highlighted the opportunities and threats in this sector and more important dilemmas focused on what needs to be carried out by the Jordanian government, including important recommendations to encourage investment in this field and inspire
