The Petrography,Mineralogy, and Hydrocarbon Potential of the Shales of the Duwi Formation,Abu Tartur,South Western Desert,Egypt

Abstract

Eight shale samples related to the Duwi Formation (Campanian-Maastrichtian) of the Abu Tartur mines of the southwestern desert of Egypt were petrographically, mineralogically, and geochemically studied. The study results indicate that the detrital material of these shales were derived mainly from mafic to ultramafic components of the basement rocks under intensive chemical weathering and deposited in an alkaline reducing marine environment of low energy and these shales do not attain the requirements of hydrocarbon production.

Mild Hydrocracking—A Review of the Process, Catalysts, Reactions, Kinetics, and Advantages

The demand for high quality middle distillates is increasing world wide while the demand for residue and fuel oil is decreasing. Hydrocracking is the major conversion process that meets the twin objectives of producing more middle distillates of very high quality. Since hydrocracking is a capital-intensive process, many refiners consider the option of converting their existing vacuum gas oil hydrotreating units into mild hydrocracking units. The use of mild hydrocracker bottom as FCC feedstock can improve the quality of FCC products. In view of the advantages of mild hydrocracking process, it is essential to understand the process, catalysts used, reactions, kinetics, and advantages. This article reviews recent literature on MHC process, various catalysts used, reactions involved and advantages of mild hydrocracking process in terms of improved product qualities and increased distillates. The kinetics of the mild hydrocracking process and kinetic challenges with respect to aromatic saturation have been summarized. The limitations of the process and future scope of work in this area are also discussed briefly.     

Characteristics and genesis of the Ordovician crude oil in the RePu area,Halahatang sag,Tarim Basin,China

The RePu area is located in the Tarim Basin, China. Based on the exploration and development, this paper analyzed the characteristics of the Ordovician crude oil and the source rocks by gas chromatography-mass spectrometry. The Ordovician carbonatite reservoir oil in this area exhibited light component, rich chain hydrocarbon and poor aromatic hydrocarbon. The composition of C7 compound showed the advantage of n-heptane, which belonged to type I generative kerogen, and it was deep buried highly mature crude oil. The crude oil biomarker compounds all exhibited high content of long-chain tricyclic terpanes and high Ts/Tm values. The large presence of alkane aromatization compounds indicated strong reducing environmental conditions during crude oil formation. By comprehensive judgment that the main oil source of the Ordovician reservoirs in the RePu area was the Cambrian source rock.     

Stratigraphy,Petrography, and Petrophysical Properties of the Subsurface Upper Cretaceous Sediments,Northwestern Desert,Egypt

Abstract

In this article, 33 core samples and 160 ditch samples of Upper Cretaceous age were studied at different depths from Horus well 1. Stratigraphic, petrographic, and petrophysical studies and well log analysis are used to study and evaluate the rock units. The studied core samples are dolomite (Abu Roash formation), shaly limestone, and argillaceous sandstone (Bahariya formation). The depositional environments of the studied rock units vary from deltaic to deltaic-marine. The effective porosity of the studied core samples is low and may be of secondary origin. The upper part of low Bahariya is considered a high category of reservoir. The stratigraphic significance of some benthonic foraminifera (Thomasinella, Nezzazata, and Nezzatine) furnishes new information on the age determination. Cenomanian-Santonian time is suggested for the studied interval (Bahariya and Abu Roash formations).     

Comparative study of imported food control systems of Taiwan,Japan, the United States,and the European Union

The growth of the global food trade has increased significantly over the last two decades. The purpose of this review paper is to compare imported food safety controls in Taiwan, Japan, the United States, and the European Union. Our key findings are: 1) imported food of animal and non-animal origin is by separate, competent authorities in Taiwan, Japan, and the US, whereas it is controlled by a single authority in the EU, 2) foreign facilities require registration in the US and Japan, 3) importing high-risk food in the EU, Taiwan and Japan requires the competent authority to inspect the food chain process and facilities in the third country, whereas a US FDA’s accredited third party auditor can do so in the US, 4) an advanced developed support systems for enabling the effectiveness and efficiency of imported food control can only be found in the EU and US. These findings may help the competent authorities responsible for imported food safety in Taiwan and the other countries to develop and enhance their own systems, not only to meet the international standards but importantly for the sake of public health protection.

Overview on the subsurface structure-tectonic controls in the northwest Bahariya,Western Desert,Egypt

A regional structural investigation was done on the northwestern part of Bahariya Oasis, using the potential field maps aided by geo-seismic sections and wells data. The gravity and magnetic maps were reinterpreted in context of geotectonic evolution of the north Western Desert to throw more light on the source of subsurface structures. Several processing methods and filtering techniques were applied to delineate locations, trends and depths of main source structures. Qualitatively, the study indicates that Bahariya horst is the highest in gravity, Sitra platform has the strongest magnetism, whereas Misawage graben is the largest in depth to the basement surface. The results were integrated to construct a tentative tectonic map, which exhibits an older folding in the NW direction intersected by a younger ENE trend, which seems to be crossed by a set of NW-trending faults. The map underlines regional folding in NE-SW trend (Syrian arc), forming four major structural features (Misawage graben, Sitra platform, Bahariya uplift and Dirrut basin), each has distinctive characteristics. The tectonic model suggests two different forces (NNW-compression and ENE-tension) affected the area, forming two main fold trends and five cycles of deformation. The models indicate a rough basement surface with a regional dip regime toward the north, overlain by a sedimentary cover ranges between 1 and 4.5 km in thickness. The basement is generally of acidic composition with some basic intrusions penetrate the boundary faults.
