Diplomarbeiten Agentur Systems for collecting and preparation of oil and gas and criteria for their selection

The production of oil is a complex technological procedure consisting of several equally important segments. One of the most important phases is the collection and preparation of oil, which affects the process of production from technical as well as from economical aspects. The choice and method of designing systems for oil collection and preparation is a very complex task that depends on the number of concrete parameters; this carries with it, above all, the difficulty in finding technology that will enable optimal work of wells as well as finding the continually and quality functioning of the entire production process. It is important to mention that each well is a case in itself; there are no broad or typical solutions for oil collection and preparation. Each production project on a field is involves individual solutions dependent upon situation-specific conditions. The most important factors in finding the best solutions are experience and knowledge of problem-solving methods in similar fields worldwide. As this is the case, this thesis is based on analysis of a selection of different fields from around the worlds that, combined, represent one system of oil collection and preparation and should satisfy even the strictest criteria. The task is: At oil-gas field (X), 27 wells are drilled and prepared in the development phase for oil and gas production. The average production of peripheral wells involves around 20 m3/24h of oil, 10 m3/24h water, 800 m3 s/24h gas; while central wells involve the production of 35 m3/24h oil 1000 m3 s/24h of gas. Pressure at the well head of the well is 30 [bar], and the temperature is 30° C. The shape of the field and layout of wells are shown in diagram (1). The following are needed to define the design: 1) optimal scheme for collection of production fluids, 2) optimal technological scheme for collective station with basic elements, 3) basic parameters of all elements for collective station. When defining the collection scheme, it About the Author Dr. Muhammed A. Mazeel Al-Aboudi has worked for many years in the international sector of the oil and gas industry in several countries. He studied at the Mines and Geology Faculty - Department of Petroleum Engineering of the University of Belgrade (Diploma in Engineering), the Escuela Superior de Minas in Madrid, Spain (Credit in Applied Geophysics Engineering) and the University of Clausthal-Zellerfeld in Germany. He was awarded a PhD in Petroleum Engineering by the Technical University Clausthal. Dr. Mazeel has been employed in European oil companies. He has also worked as Director General of the Iraqi Drilling Company (IDC) and Director General for the Oil Products Distribution Company (OPDC). At the same time, he was the oil industry adviser to the Iraqi Prime Minister Dr Ibrahim Al-Jaafari. Dr Mazeel introduces the IDC in the international Association of Drilling Contractors (IADC) and was formerly the head of the steering committee with GALP ENERGY. He is the Author of many papers on petroleum engineering for the Society of Petroleum Engineers (SPE), the Canadian Institute of Mining (CIM), Middle East Economy Survey (MEES) and the German Oil, Gas and Coal Magazine (EEZ). His next books, on Formation Damage, Reservoir Management, Exploration Strategy of own State companies and Iraq Constitution-Petroleum Resources Legislation and International Policy are in editing and will be published soon. Dr. Mazeel founded the oilgasline.com website; Iraq Research and Development Centre; and Iraqi Institutes for Petroleum industry, Infrastructure, Economics and Environmental Reforms. He lectures at the University of Baghdad for Master Students and also lectures for international courses in Gas Production Engineering, Reservoir Management, Cost Estimation and Petroleum Economics. He is the initiator of a co-operation agreement between the University of Baghdad and the University of Clausthal.
