Water injection has proven to be one of the most successful, efficient and cost-effective reservoir management strategies. By reinjecting treated and filtered water into tanks, this approach can help maintain tank pressure, increase hydrocarbon production, and reduce environmental impact. The goal of this project is to create a water injection model using Eclipse tank simulation software to better understand water injection methods to maintain tank pressure. A basic reservoir model is utilized in this investigation. The simulation was performed about 52 years using ECLIPSE Reservoir simulator. In all cases, result shows that oil production with water injection is higher compared with the base case. With this, it would be preferred to apply waterflooding for oil recovery in depleted reservoirs to the use of primary methods. It is also observed that water breakthrough is earlier and water production increases gently with water injection rates. Sensitivity on the injection rate using the 3D model showed that the injection rate has impact on the process. The pressure increases with high injection water rate in all cases. Despite higher reservoir pressure and early in water breakthrough, water flooding accounts for less oil recovery due to rapid water production. Generally, based on the results and discussions, it can be concluded that the water injection option can be used to increase the reservoir pressure to a good extent. 

The aim of the study was to investigate the mediating roles of resilience, posttraumatic growth (PTG) and religiosity between the impact of hurricane trauma and psychological distress. Using a cross-sectional design, the study involved 101 Libyan participants with an average age of 30.43 years (SD = 9.59), of whom 72% were women. Participants completed validated tests, including the Impact of Event Scale (IES), Brief Resilience Scale, Muslim Religiosity Scale and Patient Health Questionnaire (PHQ). The results indicated that posttraumatic stress symptoms (PTSS) were not associated with PTG (r = 0.04, p > 0.05) or religiosity (r = 0.02, p > 0.05) but were negatively associated with resilience (r = −0.39, p < 0.001) and positively associated with psychological distress including anxiety (r = 0.72, p < 0.001) and depression (r = 0.69, p < 0.001). Structural equation modelling (SEM) revealed that only resilience positively mediated the association between PTSS and anxiety (indirect effect = 0.04, p = 0.031), while PTSS positively predicted psychological distress (β = 0.037, p < 0.001). Network analysis identified parent loss is strongly connected with intrusion (r = 0.121), as most central node, while partner loss was associated with hyperarousal (r = 0.063), irritability (r = 0.036) and both share the same connection with numbing, while interestingly partner and friends loss share connection with resilience (r = 0.177). The study concludes that urgent clinical interventions, such as trauma-focused cognitive behavioural therapy, are required for the affected individuals, with a focus on enhancing resilience as a protective factor against PTSS.

Introduction: 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.

Large outbreaks of skin lesions in cattle have been observed recently throughout the governorate. The LSDV was

shown to be the causative factor. The local strain of LSDV was sequenced and deposited into GenBank, where it

was assigned the accession number MK552139 and designated as LSDV/Egy-BSU/2018. The discovered strain

resources were connected and to other LSDVs, however the phylogenetic tree clustered viruses of sheep pox, goat

pox, and LSD viruses independently.

Abstract: Eighty-five rock samples corresponding to the Palaeozoic formations were taken from two wells in the NC 200 Block of the Murzuq Basin. The study aimed to find out geochemical characteristics of Silurian Bir Tlacsin/Tanezzuft Formations, the Devonian Awaynat Wanin/BDS II Formations, and the Carboniferous Marar/Lower Marar Formations. Rock-Eval analysis, Total organic carbon (TOC) parameters and specific Gas Chromatography-Mass Spectrometry (GC-MS) biomarkers were applied to determine the potential hydrocarbon generation.

Abstract: 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.
