As oil spells, it is important to act as quickly as possible in order to minimize damages that can affect people and natural life. Thus, for the necessary operations to be done on time following an accident, numerical simulation of oil spell is an essential tool. The purpose of this paper is to develop a 2-D numerical model for the main operations that control and affect the trajectory and fate of an oil spill. Two additional operations had been considered, those are evaporation and dissolution which lead to lose some of the spilled oil even in air or water column. Afterwards, oil spill scenarios had been created and spreading of an oil spill, whose density and initial position are known, had been examined. Using MATLAB, flow simulations had been made and results had been discussed.

Critical review
دراسة نقدية: يعتبر هذا البحث خطوة هامة في مجال نمذجة انتشار الانسكابات النفطية، حيث يقدم نموذجاً رقمياً يمكن استخدامه لتتبع مسار البقعة النفطية وتحديد تأثيراتها البيئية. ومع ذلك، يمكن انتقاد البحث من عدة جوانب. أولاً، النموذج يعتمد بشكل كبير على البيانات المدخلة والتي قد تكون غير دقيقة أو غير متوفرة في بعض الحالات. ثانياً، النموذج لا يأخذ في الاعتبار تأثير التيارات البحرية بشكل كافٍ، مما قد يؤثر على دقة التنبؤات. أخيراً، البحث يوصي بإنشاء مركز آخر لمكافحة التلوث في مصب طرطوس، وهو توصية جيدة ولكنها تتطلب موارد مالية وبشرية كبيرة لتنفيذها. بشكل عام، البحث يقدم إضافة قيمة ولكنه يحتاج إلى تحسينات وتوسعات ليكون أكثر شمولية ودقة.

The study of the phenomenon of ship squat in vessels can be considered as one of the most important topics in ships hydrodynamic science, because it is related to the marine secure, especially now after the rapid increase in size of vessels and ope ration speeds. In literatures there are methods that are used to predict ship squat. This research aims to develop a 3D Numerical Modeling to analyze the phenomenon of ship squat of the ship in Canals using computational numerical method and proper software, to extract the velocity and pressure fields of the flow around ship hull. The last one affect directly this phenomenon. To build a 3D model and to represent ship squat for viscous flow, simulation has been developed using Gambit and Ansys Fluent programs. ship squat has been integrating the motion of water level drop. The effect of vessel speed and blockage factor Cb have been taken into account. Results confirm the efficiency of the CFD for simulating ship squat. The comparison with other experimental and computational methods show good accuracy.
Stereoscopic broadcast Tv systems,That is,Those capable of reproducing a Three-dimensional picture,give a better idea about The televised scene,enhance artistic impression,and make The reproduction more realistic so That The observer has The sensatio n of being actually present at The scene of action. For a compatible 2-d/3-d colour Tv system The channel bandwidth should be twice That of The standard broadcast Tv channel. The search for ways and means of reducing The required bandwidth without an impairment in The quality of The colour 3-d picture is a major direction in work or such systems.
The oil reservoirs exploitation processes are one of very important steps of petroleum industry. The rentability of investor reservoir is related to correct planning and accurate understanding of rock properties and liquids flow in porous media. T he complexity of porous media contains hydrocarbon materials, with phases changes related to thermo-physiochemical phenomena, make the classical methods used to study the reservoir recovery are inaccurate and insufficient to predict the performance and behavior of reservoir. Recently, simulation and modeling are used to decrease the risks in the decision of the optimal recovery method, and achieve the best possible rentability. This method provides predictive capacity help us to better understanding of reservoir. By the suitable input data, we can solve the calibrated mathematical model analytically or numerically. We present in this research the formulation of mathematical model of isotropic-one dimension reservoir with single phase fluid flow. The numerical solution, the application of this model, and the mechanism of pressure diffusivity along productive formation, will be presented to simulate a reservoir with injection and production wells.
The aim of this study is to highlight the potential use of marine algae as well as polypropylene for the removal of crude oil from surface seawater. The determination of optimal sorption time and sorption capacity of the materials in oil/water bath and oil bath without water in presence of three oils of different viscosity were investigated. The capacity of oil removal from seawater was related to structure and surface properties as well as oil amount and oil properties especially, its viscosity. The results revealed that the extension of absorption time does not influence absorption capacity of the examined sorbents in presence of both oils of low and middle viscosity (LV and MV). Nevertheless, the sorption capacity was increased by extending the absorption time to 30 min. For high viscose oil (HV). The sorption capabilities of Enteromorpha exceeded those observed for all of the other algae, while polypropylene fiber showed the highest capacity. Overall, the sorption capacity of the studied sorbents increased with increasing oil viscosity. The absorption capacities of studied materials in the oil bath and oil/water bath were comparable. The results suggested that substitution of synthetic oil sorbents used in Syria by marine algae is possible in oil removal, which have relatively high sorption capacity.
We have provided in this paper an attempt to study the deformation of oil wellbore using modeling because of its capability to analyze the different hypotheses which give us a vision of what is happening or could happen . We have built a model of the phenomenon being studied are expressed in a horizontal section of the oil well on the geological layer , after loading forces and stresses, we analyzed the results ( deformations ) for the sandstone ( elastic rock ) and clay (plastic rock ), where it is shown- by making a hypothesis fit with abnormalities in the state of the stresses in the oil fields - that the anomalies in the state of stresses of principles geological stresses plays an important role in the deformation of oil wellbore.
