Abstract

Geologic modeling is the art of constructing a structural and stratigraphic model of a reservoir from analyses and interpretations of seismic data, log data, core data, etc. ‎[1]. A static reservoir model typically involves four main stages, these stages are Structural modeling, Stratigraphic modeling, Lithological modeling and Petrophysical modeling ‎[2]. Ismail field is exploration structure, located in the north Iraq, about 55 km north-west of Kirkuk city, to the north-west of the Bai Hassan field, the distance between the Bai Hassan field and Ismael field is about one kilometer ‎[3]. Tertiary period reservoir sequences (Main Limestone), which comprise many economically important units particularly reservoir pay zone, in Ismail field are belong to middle Miocene age and Oligocene age, which includes six formations, Jeribe, Bajwan, Baba, Baba/palani and Palani formation. The information of Ismail field such as final well report, drill stem test, completion test and well logs data also previous studies and results of core data, indicated that hydrocarbons are accumulated in the Baba formation. The main purpose of this study is to make use of all the available sets of data acquired from Ismail field to build a static geological model for Baba formation in Ismail field to get full description for this reservoir. الموديل الجيولوجي هو بناء موديل تركيبي وطباقي للمكمن من خلال تحليل وتفسير المعلومات الزلزالية ومعلومات جس الابار ومعلومات تحاليل اللباب.. الخ. الموديل الجيولوجي الاستاتيكي نموذجيا يتضمن اربعة مراحل، وهذه المراحل هي الموديل التركيبي والموديل الطباقي والموديل السحني والموديل البتروفيزيائي. حقل اسماعيل عبارة عن تركيب استكشافي، يقع في شمال العراق، حوالي 55 كلم من شمال الغربي من مدينة كركوك، والى الشمال الغربي من حقل باي حسن، والمسافة بين حقل اسماعيل وحقل باي حسن حوالي واحد كلم. طباقية عصر المكمن الثلاثي (مكمن الكلس الرئيسي)، والتي تشمل تكوينات مهمة اقتصاديا خصوصا مناطق العطاء المكمني, في حقل اسماعيل تعود الى عصر الاوليجوسين وعصر الميوسين الاوسط وتتضمن ستة تكوينات هي جريبي , باجوان الصلد , باجوان المسامي , بابا , بابا/بالاني , بالاني. المعلومات حول حقل اسماعيل مثل التقارير النهائية للبئر والفحوصات الاكمالية ومعلومات جس الابار وكذلك الدراسات السابقة ومعلومات تحاليل اللباب، كلها تشير الى ان الهيدروكاربونات تجمعت في تكوين (بابا). الهدف الرئيسي من هذه الدراسة هي استخدام كل المعلومات المتوفرة والمستحصلة من حقل اسماعيل لبناء موديل جيولوجي لتكوين (بابا) في حقل اسماعيل لحصول على الوصف الكامل لهذه المكمن.

Abstract

Rock type identification is very important task in Reservoir characterization in order to constrict robust reservoir models. There are several approaches have been introduced to define the rock type in reservoirs and each approach should relate the geological and petrophysical properties, such that each rock type is proportional to a unique hydraulic flow unit. A hydraulic flow unit is a reservoir zone that is laterally and vertically has similar flow and bedding characteristics. According to effect of rock type in reservoir performance, many empirical and statistical approaches introduced. In this paper Cluster Analysis technique is used to identify the rock groups in tertiary reservoir for Khabaz oil field by analyses variation of petrophysical properties data that predicted by analysis of well log measurements. In tertiary reservoir four groups identified by cluster analysis technique, were each group was internally similar in petrophysical properties and different from others groups.

Abstract

This paper displays a survey about the laboratory routine core analysis study on ten sandstone core samples taken from Zubair Reservoir/West Quarna Oil Field. The Petrophysical properties of rock as porosity, permeability, grain's size, roundness and sorting, type of mineral and volumes of shales inside the samples were tested by many apparatus in the Petroleum Technology Department/ University of Technology such as OFITE BLP-530 Gas Porosimeter, PERG-200TM Gas Permeameter and liquid Permeameter, GeoSpec2 apparatus (NMR method), Scanning Electron Microscopy (SEM) and OFITE Spectral Gamma Ray Logger apparatus. By comparing all the results of porosity and permeability measured by these instruments, it is clear a significant variation in the values with the depth within same formation. The porosity by gas, liquid and NMR are varied (15.4 - 35.9) %, (4.6 - 22.3) % and (2.4- 13.5) % respectively, While the permeability by gas, liquid and NMR were altered (0 - 512) md, (0-139.6) md and (1.577 x10-6 – 492) md respectively.

Abstract

Nanotechnology has shown a lot of promise in the oil and gas sectors, including nanoparticle-based drilling fluids. This paper aims to explore and assess the influence of various nanoparticles on the performance of drilling fluids to make the drilling operation smooth, cost effective and efficient. In order to achieve this aim, we exam the effect of Multi Wall Carbon Nanotube and Silicon Oxide Nanoparticles as Nanomaterial to prepare drilling fluids samples. Anew method for mixing of drilling fluids samples using Ultra sonic path principle will be explained. Our result was drilling fluids with nano materials have high degree of stability. The results of using Multiwall Carbon Nanotube and Silicon Oxide show that MWCNT have an effect on rheological properties more than SiO2 and good thermal conductivity. Also, both nano particles have potential effect on filter loss and stability of mud. The change in density was insignificant which is beneficial for many drilling operations. أظهرت تقنية النانو مستقبل واعد في قطاع صناعة النفط و الغاز و التي تتمثل بموائع الحفر ذات الاساس النانوي. هذة الدراسة تهدف لشرح و توضيح تأثير مواد نانوية مختلفة على ادائية سوائل الحفر لجعل عمليات الحفر اكثر سهولة و مرنة و مجدية من الناحية الأقتصادية. و لكي يتم انجاز الدراسة, تم اختبار تاثير الكاربون متعدد الجدران النانوية و اوكسيد السيليكون النانوي لتحضر نماذج سوائل الحفر و فحص خواصها. تم استخدام طريقة لغرض خلط نماذج الحفر باستخدام الموجات فوق الصوتية قد قدمت في هذة الدراسة و ايضا طريقة جديدة لغرض اختبار استقرارية الطين قد تم شرحها في هذة الدراسة, النتائج اعطت استقرارية عالية لطين الحفر الذي يحتوي على مواد نانوية. تم استخدام طين Ferro chrome lignosulfonate لدراسة تاثير المواد النانوية. النتائج اظهرت بان الطين يسلك الموديل power law and Bingham models. تاثير المواد النانوية على الكثافة كان قليل نوعا ما حيث ارتفعت بمقدار 4% لل SiO2و 6% للMWCNT. مقدار التغير باللزوجة الظاهرية كان بمقدار 15 cp للMWCNT و بمقدار 6.5 cp لل SiO2. التغير باللزوجة البلاسيتيكية كان قليل جدا او غير محسوس مع نقصان قليل بالنسبة للSiO2 بسسب الشكل الكروي الذي يأدي الى تقليل الاحتكاك بين الجزيئات. الزيادة في نقطة الخضوع كانت بمقدار 30 Ib/100 ft2 بالنسبة للMWCNT و بقدار 15 Ib/100 ft2 للSiO2 و السبب يعود الى نسبة العالية للشد السطحي الى الحجم للمواد النانوية. مقدار التصلب لطين الحفر كان عالي بسبب قوى التماسك الكبيرة للمواد النانوية. التجارب اظهرت مقدار ترشيح قليل للاطيان التي تحتوي على مواد نانوية بسبب حجمها الصغير مما يؤدي الى غلق مسامات ورقة الترشيح بسرعة كبيرة. ان كعكة الطين المتكونة على ورقة الترشيح كانت رقيقة جدا و ذات خواص زيتية مما يعطي انطباع جيد لحل مشكلة استعصاء الانابيب. الاطيان التي تحتوي على مواد نانوية اظهرت درجة عالية من الاستقرارية و السبب يعود الى كمية الشد السطحي العالية الى الحجم.

Abstract

Nano-crystalline iron oxide nanoparticles (magnetite) was synthesized by open vessel ageing process. The iron chloride solution was prepared by mixing deionized water and iron chloride tetrahydrate. The product was characterized by X-Ray, Surface area and pore volume by Brunauer-Emmet-Teller, Atomic Force Microscope (AFM) and Fourier Transform Infrared Spectroscopy(FTIR) . The results showed that the XRD in compatibility of the prepared iron oxide (magnetite) with the general structure of standard iron oxide, and in Fourier Transform Infrared Spectroscopy, it is strong crests in 586 bands, because of the expansion vibration manner related to the metal oxygen absorption band (Fe–O bonds in the crystals of iron oxide). The results show that the prepared nano iron oxide is with average crystal size 75.92 nm, surface area was 85.97 m2/g and the pore volume was found equal to 0.1566 cm3/g.

In this work the production of activated carbon (AC) from Imperata is done by microwave assisted Potassium hydroxide (KOH) activation and using this activated carbon for the purpose of the uptake of amoxicillin (AMX) by adsorption process from aqueous solution. The effects for irradiation power (450-800W), irradiation time (6-12min) as well as impregnation ratio (0.5-1 g/g) on the AMX uptake and yield AMX uptake at an initial concentration of AMX (150 mg/g). The optimum conditions were 700 W irradiation power, 10 min time of irradiation, as well as 0.8 g/g impregnation ratio with 14.821% yield and 12.456 mg/g AMX uptake. Total volume of hole and the area of the surface (BET) are 0.3027 m³/g, and 552.7638 m²/g respectively. The properties for the activated carbon were examined via Scanning Electron Microscopy (SEM).
