Facies Analysis and Reservoirs Characterization of the Ordovician Hawaz and Memouniyat Formations and the Devonian Awainat Wanin Formation, Area 176-4, Murzuq Basin, SW Libya
Conference paperAbstract: The Ordovician to Devonian succession in the in Murzuq Basin represents the most important part of the lower Paleozoic terrigenous Al Gargaf siliciclastic group, which consists of several formations such as the Ordovician Hawaz, Melaz Shuqran and Mamuniyat Formations and the Devonian Tadrart and Awainat Wanin Formations. Different integrated methods were used and implemented in order to understand lithology and sedimentary structures of the Ordovician, Silurian and Devonian formations. Firstly, intensive geological field trips were carried out and special attention was focused on Ordovician and Devonian reservoir sandstones and the Silurian source rocks. Secondly facies analysis and sequence stratigraphy methods were applied to figure out a simple sequence stratigraphic division of the Ordovician to Devonian succession based on outcrop sections, well logs and interpreted seismic sections. As a result of the petrographic field investigation and facies analysis based on seismic interpretation of the several seismic lines in the study area. Sequence boundaries of the Ordovician and Devonian succession on all seismic sections were identified by using specific reflection terminations such as onlap and erosional truncations features. 13 seismic facies were recognized, divided and classified for each of the examined stratigraphic formations (4 facies in Hawaz, 5 facies in Melaz Shuqran and Mamuniyat formations and 4 facies in the Tadrart and Awainat Wanin). A seismic facies classification chart was made on the basis of the classified seismic facies scheme, since depositional systems and types of seismic facies differ in each stratigraphic succession. Depositional sequences of sedimentary environments were identified from well logs and available 2D seismic sections and sequence stratigraphic frameworks were constructed for the Ordovician and Devonian formations. Based on the facies analysis and sequence stratigraphy interpretations, two different order sequences in the Ordovician to Devonian succession have been found and identified: The major sequences are possibly 2nd-order sequences in time duration. They are clearly traceable on all seismic sections. May be minor sequences are possibly 3rd-order sequences, and they are not traceable on all seismic sections clearly, but are recognized on well logs or outcrop sections. Eventually, all obtained information and that results were plotted on the different maps for each examined section to construct a depositional model and to estimate the maximum distributions of each formation separately on the basis of depositional system interpretations.

Computational Studies of the Active Metabolite of Triflusal Molecular Orbitals and Spectroscopic Features; The Basis for Triflusal Phototoxicity Mechanism
Journal ArticleTriflusal is a prodrug used as a platelet antiaggregant agent (a platelet aggregation inhibitor). It has efficacy similar to that of aspirin specially in patients with cerebral and myocardial infraction. Chemically, triflusal is nothing except a derivative of acetylsalicylic acid (2-acetyl-3-trifluoromethylsalicylic acid). It is bio-transformed under the effect of a deacetylation process into the active metabolite (known as HTB) which is 2-hydroxyl-3-trifluoromethylbenzoic acid. During the triflusal uses the cutaneous phototoxic/photoallergic side effect is noted including rash, itching or allergic reactions. In order to study this side effect, we use a very excellent tool to study such reactions which is DFT and TD-DFT. The active metabolite of triflusal HTB molecular orbitals and UV-VIS spectroscopic features have been investigated herein. The obtained results show that there is a difference in the molecular orbitals (MOs) pattern between the two forms of HTB (protonated and deprotonated) especially the HOMOs of the deprotonated species..

The cross-link between maternal HbA1c and neonatal outcome: A Clinical Case Report
Journal ArticleIntroduction: Diabetes is a common condition among pregnant women, and a high glycated haemoglobin (HbA1c) level can indicate poor outcomes for both the mother and the fetus. This report presents a case of an unknown diabetic primigravida with a significantly elevated HbA1c level, which resulted in severe complications during pregnancy and adverse fetal outcomes. Case Study: A 37-year-old primigravida was referred to the emergency obstetrics and gynaecology clinic, where she reported a notable decrease in fetal movements and feelings of lethargy. Laboratory tests revealed a significantly elevated blood sugar level. After assessing fetal well-being, the decision was made to terminate the pregnancy at 33 weeks and 2 days due to severe fetal distress. Immediate treatment was initiated to control the high blood sugar levels. The outcome was the delivery of a preterm boy who presented with multiple biochemical imbalances and required admission to the neonatal intensive care unit (NICU). Conclusion: Improving hyperglycemia and glycated haemoglobin levels to lower than the upper normal limits during both the preconception and post-conception phases can significantly reduce morbidity and mortality for mothers and their fetuses.

مخاطر الجماعات الإرهابية على الأمن الوطني الليبي _ المسؤلية وسبل المواجهة (2011-2022)
مقال في مجلة علميةالملخص
كما هو الحال في كل الدول التي شهدت ثورات شعبية خلال العام 2011، لم تأت الرياح بما تشتهي السفن، وتطور التظاهر السلمي في الكثير من المناطق إلى عنف من قبل أنظمة الحكم السائدة ، أو إلى تدخل دولي أو إقليمي، أو إلى صراع سياسي بين نُخب ما بعد الثورة، أو إلى حروب أهلية بين تشكيلات مُسلحة وقوى أخرى نظامية أو غير نظامية . لكن المهم إدراكه هو أن الوضع الراهن الذي آلت إليه ليبيا منذ أحداث فبراير 2011 في ظل غياب معايير واضحة، وتقلص سيادة الدولة وشرعيتها، وغياب الإستقلالية عن المؤسسات القضائية، وتهاوي دور القانون، وضعف المؤسسات الأمنية وإنتشار السلاح في كل مكان داخل ليبيا، أدى الى انتشار الجماعات الإرهابية التي وجدت في هذه الأوضاع فرصة مناسبة للتوطن والنمو.
تبلورة المشكلة البحثية على هيئة تساؤل رئيس على النحو التالى : ما تأثير الجماعات الإرهابية على الأمن الوطني الليبي عقب ثورة فبراير 2011 وما ابرز أطر الإستراتيجية المقترحة للتغلب على تلك الجماعات؟
وخلصت الدراسة للنتائج التالية
1-منذ بداية الثورة الليبية فرض على حركة التغيير والإحتجاج التحول السريع عن المسار السلمي إلى حمل السلاح لتدخل مباشرة إلى صراع مسلح مفتوح بين الطرفين (النظام والمعارضة).
2-إن طرفي الصراع قد عمدا إلى الإستعانة بأطراف خارجية (المرتزقة، الناتو) في سعي كل طرف لحسم الصراع لصالحه.
3-أنه على عكس الحالتين التونسية والمصرية التي أسفرت عن تداعي رموز النظام والدخول في مرحلة البحث عن صيغة جديدة لمرحلة ما بعد النظام، شهدت الحالة الليبية جموداً في أرض الواقع في ظل عجز كل طرف عن حسم الموقف لصالحه.
4-إفتقرت الثورة الليبية إلى مؤسسات مجتمع مدني تتبناها وتدعمها في ظل عدم وجود مثل تلك المؤسسات على الساحة الليبية وعدم مشروعيتها.
5-المشهد السياسي الليبي بعد الثورة شهد حراكاً غير مسبوق وتفاعلاً بين كافة التيارات من أجل الحصول على نصيب الكعكة في السلطة السياسية، سواء من قبل المجلس الوطني الإنتقالي أو الإسلاميين أو الشباب الذين فجروا ثورة 17 فبراير، ومختلف فئات الشعب الليبي التي أنضمت إليهم، خرجوا من أجل المطالبة بحقهم في الحرية والديمقراطية والمناداة بعدم الإقصاء .

التعدد الأثني في ليبيا و أثره على تجانس المجتمع و تمتين روابط الوحدة الوطنية
مقال في مجلة علميةالملخص
تناولت هذه الدراسة التعدد الاثني والتركيب القبلي في ليبيا ودوره في تأكيد الانتماء الوطني ، والذي يعد من المواضيع المهمة خاصة في ظل ما تمر به الدولة الليبية من تراجع في مقومات الوحدة الوطنية على حساب الانتماءات الفرعية الاخرى ، فقد تعايشت هذه المكونات بشكل سلمي في هذا المجال الجغرافي منذ عصور طويلة ، وتوافقت فيما بينها رغم صعوبة ظروف الاقليم الجغرافية وشح موارده ، لتكون ليبيا بذلك نموذجا للدولة التي استطاعت ان تتثبت ان التنوع العرقي والتركيب القبلي لا يشكل خطر على الدولة بل يمكن الاعتماد عليه في تقوية الاندماج الوطني للسكان ، وترابطهم ثقافياً وفكرياً يجمعهم في ذلك انتماؤهم الوطني الذي لا يتناقض مع الانتماء القومي أو القبلي والذي يظل محل احترام واعتزاز به وعدم تجاهله وتهميشه ، فهذه المكونات الثقافية رغم تباينها لكنها جسدت الهوية الليبية ، وإن ليبيا وطن تسكنه مجموعات بشرية تكون الأمة الليبية .

A Comparative Study of Water and Gas Injection Simulation in Libyan X Field Using Eclipse Software
Conference paperThe main goal of this study (which the comprehensive reservoir study for Libyan X Field plan of development) is to predict future performance of a reservoir and find ways and means of optimizing the recovery of some of the hydrocarbon under various operating conditions. The simulator results show the reservoir pressure history curve is matching to the stimulation curve, this gives a good indication of the input data that has been entered to the model. The driving mechanism for all those reservoirs it comes from three natural forces, which are fluid expansion, PV compressibility, and water influx. The best method to choose as secondary recovery for this oil field is water and gas Injection. Water and gas Injection have the largest Total Field Recovery. Water and gas Injection have the highest Reservoir Pressure at the end of the project. The highest percentage of oil recovery was when the water and gas were injected and it reached 58%, then when the water was injected and it reached 55%, and then when the gas was actually injected and it reached 54%. The field pressure rise was greater when water and gas were injected, and the pressure reached 792 psi, while it was less when only water was injected, reaching 435.5 psi, and when only gas was injected, it reached 412.9 psi. Finally, central objective of this master thesis with the help of reservoir simulation fulfilled to produce future prediction that will lead to optimize reservoir performance which meant reservoir developed in the manner that brings utmost benefit to the commercial business.

Evaluation the Primary Drive Mechanisms and PVT Analysis by using Material Balance Software (MBAL Software) for Intisar “D” Reef Reservoir
Conference paperIdentifying the driving mechanism and PVT analysis is important for optimizing reservoir development plans through primary, secondary, or tertiary recovery methods. Also, determining the size of an aquifer (based on its response to pressure support) provides a means of calibrating known physics against production data, which once calibrated can be used for prediction. In this paper, the types of natural drivers of the reservoir were estimated and compared using a program called MBAL after matching production history data with model results. The purpose of this paper is to evaluate the basic driving mechanisms and PVT analysis using MBAL software for Intisar D field. The final project results can be seen matching the real data of the reservoir with the program results using MBAL software. The simulation results show that the reservoir pressure history curve matches the stimulation curve, and this gives a good indication of the input data fed into the model. The driving mechanism for all these tanks comes from three natural forces, namely fluid expansion, compression, and water flow. It started with the expansion of the fluid from 0 to 0.60, with the compressibility from 0.60 to 0.89, and with the flow of water from 0.89 to 1 is the flow of water.
