Evaluation of Al Hawaz Reservoir using Core Sample Analysis and Petrophysices Study in )O), Oil Field, Concision NC 115, Morzuq Basin.

The O field which belongs to Akakus Oil Operation which is located in north north west (NNW) of Murzuq basin , NC 115 Concession, It is 30 km west of Awbari. The main objectives of this study were to provide for the reservoir model of the Hawaz Formation: A detailed sedimentological and fracture description with the identification of significant stratal boundaries, maximum flooding surfaces, discontinuities and other internal structures of the supplied core, The description included determination of the lithology, grain-size, sorting, color, sedimentary structures, bed contacts, abundance of clay, degree of bioturbation and the presence of fossils. To describe and characterise the vertical distribution of sedimentary facies and provide an interpretation of the depositional environments in terms of sequence analysis. Construct a depositional model, based on regional knowledge and relevant data integration. A petrographic description on selected samples, including SEM and XRD analysis, to characterise detrital and authigenic mineral composition, internal fabric and diagenetic processes of identified facies, in relation to porosity and permeability. The reservoir is sealed by Tanezzuft shale, which is as a source rock also The porosity of this reservoir sandstone ranges between 11 to 15 % ,The water saturation is from 11 to 15 %. also based on petrophysices method, I have selected one well study to support the results that obtained from petrography study to get more results such as lithology identification, porosity ,permeability and mineral composition also to calculate the reservoir properties such as volume of shale, water and oil saturation, oil water contact and reservoir reserves, the initial oil in place is 804 MMSTB and the recoverable reserve is 178.5MMSTB.

دراسة الأهمية الاقتصادية لبعض الأحجار الرملية بشمال غرب ليبيا

أجريت الدراسة على رمال السليكا الواقعة بمنطقة الدراسة جنوب شرق نالوت لغرض تقيمها اقتصاديا لصناعة الزجاج . حيث كان اجمالى العينات المأخوذة من منطقة الدراسة 30 عينة أخذت من خمس مناطق شملتها الدراسة الحقلية بالموقع المذكور. وشملت الدراسة المعملية الوصف الصخري ، التحليل المنخلي للعينات المدروسة ،ودراسة التركيب المعدني لشرائح صخرية بواسطة المجهر المستقطب لغرض الدراسة البتروجرافية ولعينات رملية بواسطة حيود الأشعة السنية (XRD). هذا وشملت الدراسة التحاليل الكيميائية للعينات الرملية المدروسة لمعرفة تراكيز العناصر الاساسيةبواسطة جهاز بالبث الطيفي البلازمي ICP) ) كما تم فصل المعادن الثقيلة. وبينت نتائج التحليل المنخلي بأن الشكل الحبيبي لمعظم العينات مستدير إلى شبه مستدير وتصنيفها جيد. وأثبتت نتائج التحليل المعدني بجهاز حيود الأشعة السنية تواجد معدن الكوارتز مع كمية قليلة من اكاسيد الحديد ،وكان متوسط المعادن الثقيلة في العينات 0.3% .هذا و أظهرت دراسة الشرائح الصخرية، عدد من المعادن الثقيلة من ضمنها التورمالين والزركون وبينت نتائج البث الطيفي البلازمي نسبة مجموعة اكاسيد منها : اكاسيد الصوديوم (Na2O3) وأكسيد الالومنيوم((Al2O3 واكاسيد الحديد((Fe2O3 . وبيت التحاليل الكيميائية إن نسبة السليكا عالية في العينات تصل ( 97.70 % ) ونسبة الرطوبة منخفضةلاتتجاوز 2%، وبالتالي تعطى هذه النتائج قيمة اقتصادية جيدة لهذه الرمال . وخلصت كل هذه النتائج على إمكانية قيام صناعات على هذه الرمال مثل صناعة الزجاج الزجاج وصناعات مواد البناء المختلفة والطلاء وورق الصنفرة.

Petrophysical Study of the Nubian Sandstones in Concession 59D, E. Sirt Basin, Libya

Abstract The Nubian Sandstone Formation is a significant hydrocarbon reservoir in the Concession 59D, Eastern Sirt Basin, Libya. This formation is underlain uncomfortably by granitic basement and/or by the Hercynian unconformity and overlain uncomfortably by Pre-Upper Cretaceous followed by an Early Upper Cretaceous Transition beds. The Nubian formation is a thick sequence comprises mainly of sandstone, siltstone and shale.The Nubian Formation in this area has been subdivided into three stratigraphic members; namely Lower Sandstone, Middle Shale and Upper Sandstone (main reservoir well be focus of this study).The Upper Sandstone is the upper most subdivision of the Nubian Sandstone sequence consists mainly of white, grey to brown sandstones, ranging from fine to medium, locally coarse grained, moderately cemented with straight to concavo convex or slightly sutured grain contacts. This reservoir is a complex of fluvial sands deposited in Braided and Meandering streams.The reservoir fluids are very rich retrograde condensate gas and waxy oil with pressure at slightly above the saturation pressure. Most of this hydrocarbon in this reservoir has been sourced from the Nubian Middle Shale Member, but the Upper Cretaceous shale and Evaporates belonging to the Transition beds sequence have a significant potential source. The trapping mechanism in the field is a combined structural and stratigraphic trap for the Nubian Sandstone with the southern closure against the tight Nubian facies and basement of the Gialo High. Reservoir properties across the North Gialo Study Area vary in terms of porosity, permeability fluid saturation. These variations are indicated through the porosity, permeability and saturation maps and charts based on well log analysis and lab core sample measurements. These properties are discussed in the reservoir characterization part of this thesis.
