About Faculty of Science

Faculty of Science

The Faculty of Science is the core at the University of Tripoli, as it was the first that established in this prestigious university. It is also the first faculty of science in Libya. At the present, it includes ten scientific departments: Departments of Zoology, Mathematics, Physics, Chemistry, Botany, Geology, Computer Science and Statistics, Atmospheric science and geophysics. It currently works to create a new department of Archaeology in order to study the scientific and research side of the historical heritage of the Libyan people. Graduates of this college have worked in various governmental sectors, such as oil exploration, extraction and refining, chemical industries complexes in Abu Kamash and Ras Al-Anuf, as well as plastics companies in production and manufacturing, and in factories for soap, cleaning materials and others. They were also recruited by the education sector in different research and pedagogical areas.

 

The graduates of this faculty have led the scientific process for many years and still represent the first building block in all colleges of science, and some other colleges in all Libyan universities for the past five decades. The scope of work for graduates included Faculties of Medicine (in the field of basic sciences, biochemistry, anatomy, histology and microbiology), many departments in the Faculty of Agriculture, general engineering, chemical and geological engineering; in particular, medical technology and pharmacy, and the Faculty of Economics and Arts. The Faculty of Science provides teaching assistants to other faculties and universities in the Libyan state.

 

The Faculty of Science is the first to create graduate studies programs in Libya, despite the nature of graduate studies in basic sciences, which need capabilities other than competent professors. Teaching staff in this institution graduated from international universities in the West and the East (USA, UK, Australia, and other European countries). They graduated from universities that are well-known for their high academic standard.

 

Having obtained their first university degree or higher degrees of specialization from Libya or abroad, graduates of Faculty of Science worked for industrial and nuclear research centers, petroleum sector, marine life, biotechnology, plastics, and other specialized research centers.

 

The Faculty has also enriched the scientific research movement in the fields of basic sciences in the Libyan state through the issuance of refereed basic science journal.

Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field, Southeastern Sirt Basin, Libya

Abstract The Sarir Sandstone in Messla Oil Field are of Lower Cretaceous ageAptian Alpian and occur in the subsurface of the eastern part of the Messla high in the southeast Sirt Basin. The Sarir Sandstone interpret as fluvial and alluvial fan deposits whereas the Lower Sarir Sandstone were deposited in a braided system as inter-channel bars. The Upper Sarir Sandstone were deposited in the meandering belt of the fluvial system. The Sarir Sandstone is on-lapping Formation and wedge out against Rakb Group. The Sarir Sandstone is unconformable overlies the Pre-Cambrian Basement and unconformable overlain by the Upper-Cretaceous Rakb Group where it is pinching (wedging) out against the Bald Basement; Messla High)). Lithostratigraphic correlations of borehole logs ((well logs)) in concession 65 suggests that deposits gradually downed a fault controlled topographic surface increased in thickness on the down-thrown side of a fault controlled the topographic surface of Pre-Upper Cretaceous Unconformity. IV M. Sc. Hassin Haweel “Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field”, 2015 Core Samples record mainly sandstone units interbedded with sandstone and shale and minor streaks and the Red Shale Unit. Estimation of depositional environment has thus been made from grain size analyses using thin sections. Petrographic studies show that the Sarir Sandstone in composition from (subarkose to arkosic arenite). The Sandstones range from texturally immature to submature, however, much of the clay content is diagenetic in origin and not a function of the depositional regime. Diagenetic studies reveal a gnite complex paragenesis. During early diagenesis, the Sarir Sandstones were modified by Calcite, dolomite, and locally pyrite, diagenesis process; replacements of corroded silica by carbonates. Cementation fluvial sandstones Intrastratal dissolution and precipitation of kaolinite in the resulting pore space. Deformation of micas between more resistant grainy pre-dates one phase of quartz overgrowth, probably the carbonates.The purpose of this study was to investigate in detail the characteristics of the Sarir Sandstone in Messla Oil Field. Another aim was to find out the relation to the adjacent area. The method of this study was conducted with the review of the previousworks in Messla Oil Field; published papers, the open file of the Arabian Gulf Oil Company (AGOCO), well files for the data to be used in constructing maps, cross sections and profiles. Four cored wells (418 feet) V M. Sc. Hassin Haweel “Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field”, 2015 were used for the core descriptions and cut samples that represent the Sarir Sandstone and (130) thin sections were used for the Petrographic analysis with polarized and scanning electron microscopes (SEM). On the other hand, XRD and XRF were not available. The results of the study were: Subsurface investigations including cores (conventional and side walls), petrographic analysis, and wire-line logs suggested that this formation (Sarir Sandstone) can be divided in to three main units in Messla Oil Field; these units are: The Lower Sarir Sandstone, the Red Shale, and the Upper Sarir Sandstone. In the adjacent area Sarir Formation was divided in to five members; Pre-Upper Cretaceous Member-1 unconformably overlying Pre-Cambrian Basement, and upwards; Member 2, Member 3, Member 4, and Member 5 unconformably overlain by Rakb Group. The Lower Sarir Sandstone in Messla Oil Field is characterized by the presence of gravely sandstone, gradually changes in to the Red Shale. Also, from the core descriptions plotted sheets, and the well logs it is finning upwards. The quarzitic sandstones of (the Lower and the Upper Sarir Sandstones) are considered to be the main producing horizons where quartz grains have undergone a complex diagenetic history, including: Authigenesis, quartz and feldspar overgrowths, dissolution, carbonates cementation, and replacement. The principal conclusion was that: the gravelly sandstone unit at the Lower part of the Lower Sarir Sandstone was deposited, most likely in a braided system as inter-channel bars. The sandstone unit of the Upper Sarir VI M. Sc. Hassin Haweel “Sedimentological Aspects of the Sarir Sandstone in Messla Oil Field”, 2015 Sandstone was deposited in the meandering belt of the fluvial system. The shale facies of the Red Shale unit represents a well-developed break between the Lower Sarir Sandstone and Upper Sarir Sandstone units; it also provides a good seal for the underlying sandstone of the Lower Sarir Sandstone. The nature of the shale facies, (i.e. lack of organic content, and presence of oxidizing conditions indicated by iron oxides color, indicate that they are not a significant source of hydrocarbons. On the other hand, the Rakb Shale isthe only source rock in the studied and adjacent areas.

On Prime Near-rings with Generalized Derivations

خلال العقود القليلة الماضية بحوث كثيرة تم تقديمها في خاصية التبديل في الحلقات الأولية مع الاشتقاق، وكان من الطبيعي دراسة نتائج مماثلة في قرب الحلقات. وأول دراسة قدمت كانت في سنة 1987 من قبل الباحثان (H.E.Bell and G.Mason)، ومنذ ذلك الوقت الكثير من الباحثين أثروا هذا الموضوع في اتجاهات مختلفة. التشاكل الجمعي يقال عنه تعميم للاشتقاق إذا كان يوجد اشتقاق على حيث أن. For all الهدف الأساسي في هذا البحث هي نظري (9, Theorem 3). ولكن هنا يجب إن نشير إلى إن البرهان المعطي كان غير صحيح، وفي هذا البحث تم تصحيح البرهان وذالك العمل دفعنا إلى تعميم التمهيدية (Lemma 3.2.3) التي من خلاله استطعنا تصحيح البرهان Abstract Over the last few decades, a lot of work has been done on commutativity of prime rings with derivations. It is natural to look for comparable results on near-rings, here we should mention that the first investigation of derivation of near-rings was initiated by H.E.Bell and G.Mason in 1987.Recently, some results concerning commutativity in prime near-rings with derivation that have been generalized in several ways. An additive endomorphism is called a generalized derivation if there exist a derivation of such that for all in. The main object of this thesis is a result stated in [9, Theorem 3], here we should mention that the given proof was not correct. At this point it is interesting to continue our investigation by providing some technical result which enables us to establish the correct proof of this result.

Geological study of the Early and Late Cretaceous Clastic Reservoirs in C-structure, Block nc-98, Al hameimāt Trough, Sirt Basin-Libya

Abstract The area of study is located in the southeastern part of Block NC98 and is informally named C-Structure area, and it is completely situated in the center of Al Hameimāt Trough, South East Sirt Basin, Libya. The main reservoir rock in this structure is the Upper Nubian Sandstone Member, whereas the Reworked Sandstone Unit and Transitional Beds are considered as secondary reservoir rocks. These reservoirs are mainly composed of sandstone to argillaceous sandstone. The Upper Nubian Sandstone reservoir quality is adversely affected by volcanic rocks especially the thick intercalation of volcanoclastics within the Upper Nubian Sandstone. The Upper Nubian Sandstone Member was deposited during Early Albian times. The Reworked Sandstone Unit was possibly deposited in Cenomanian? to Turonian times and may be related to the overlying Transition Beds.Up to date, four wells have been drilled in this structure (C1-NC98, C2-NC98, C3-NC98 and C4-NC98) and were targeting the clastic reservoirs of the Upper Nubian Sandstone and/or overlying Upper Cretaceous Transitional beds and Reworked Sandstone unit. Only C1-NC98 and C2-NC98 wells have tested significant hydrocarbon in the Upper Nubian and Reworked Sandstone unit whereas C3-NC98 and C4-NC98 wells have tested no hydrocarbon in both reservoirs and are abandoned as dry wells. This study is aimed to validate the stratigraphical aspects, depositional environment and reservoir quality assessment in order to decipher the reasons of drilled dry holes. The obtained results are anticipated to provide valuable geological information for the current and future prospect evaluation in the area. All available wire line logs of C wells (C1-NC98, C2-NC98, C3-NC98 and C4-NC98) and adjacent wells have been used to correlate the stratigraphy of the Pre-Upper and Upper Cretaceous silisiclastic sediments in the area of study.Representative core samples across the reservoir rocks of the candidate wells have been laid down for core description. The acquired results have been integrated with conventional core analysis and petrographic results to investigate the lithofacies characterization and depositional environment in order to sub-divide them into different lithofacies.Different types of geological maps have been prepared in this research (e.g. stratigraphical/structural cross sections, subcrop maps, isobach maps, structure contour maps and etc.) to delineate the formation extension and correlation. Burial history diagrams across all depositional sequences in the candidate wells were also prepared to identify the depositional scenario and to estimate the time span of tectonic subsidence along the depositional sequences.The results of all available geological studies which recently have been carried out by Waha Oil Company in the area of study and adjacent areas have been reviewed, elaborated and integrated with the results of this study to assess the discussion and final conclusion. The final results of sedimentological study indicates that there is no major effect of diagenetic processes on the reservoir rocks during and after the deposition. As a consequence, C3-NC98 and C4-NC98 wells were drilled in an area of poor reservoir quality of Reworked Sandstone and Upper Nubian reservoirs due to the existence of thick sequences of clay and siltstone which were mostly deposited in levee and over bank sub-environments of likely combined braided and meandering river. Whereas, C1 and C2-NC98 oil wells were drilled in an area of good reservoir quality of Reworked Sandstone and Upper Nubian Sandstone reservoirs where the sand bars sub-environment are deposited as a thick sequence of clean sands carrying the genetic of good reservoir properties. Therefore, the reservoir rocks in this area have different properties due to different sub-environment of deposition. This new results will probably assess the prospect generation and evaluation for the future drilling activity in the area of study.The encountered volcanoclastic sediments in well C2-NC98 reveals that this sediment is likely transported by river from the area of volcanic eruption to the area of deposition rather than in situ eruption. This type of volcano is likely applied to cinder cone volcano type where the pyroclastic fragments are not cemented together and thus easy to erode. Therefore, the intercalation of volcanoclastic sediment in Upper Nubian Sandstone has no marked effect in the reservoir rocks.Burial history curves of wells C1-NC98, C2-NC98, C3-NC98 and C4NC98 indicate three major subsidence events took place during Early Cretaceous time (Early Aptian - Early Albian), Late Cretaceous time (Turonian - Maastrichitian) and the Palaeocene - Eocene subsidence. However, Plaeocene - Eocene subsidence shows the highest subsidence rate with comparison to the other two subsidence rates.
