AN EXPERIMENTAL INVESTIGATION OF POSSIBLE PRODUCTION MECHANISMS OF HYDRATE FORMATION Engüçlü, Hasan Hüseyin; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2021-9-10) In this study, temperature, pressure and mole values of methane hydrate formation and dissociation are analyzed using different production methods under laboratory conditions. During the experiments, a cylindrical high-pre...
MODELING AND SIMULATION OF THE FLUID FLOW IN ARTIFICIALLY FRACTURED AND GEL TREATED CORE PLUGS Kaya, Onur Alp; Durgut, İsmail; Department of Petroleum and Natural Gas Engineering (2021-9) The dynamics of fluid flow in the matrix and in the fractures are significantly different from each other. Fractures are highly permeable flow pathways and are generally considered as the main flow unit. On the other hand,...
Carbon dioxide sequestration and enhanced oil recovery co-optimization Akhundov, Nuri; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2021-9) The worldwide growth of industry leads to continuous rise of anthropogenic emission amount into the atmosphere, which causes greenhouse effect all over the world, that is heating up the atmosphere and changing the global c...
Geochemical modeling of NCG injection in a geothermal well using doublet well model İlgin, Buğrahan; Akın, Serhat; Erol, Selçuk; Department of Petroleum and Natural Gas Engineering (2021-7-29) Geothermal energy is regarded as an environmentally friendly source of energy. However, the amount of non-condensable gases (NCG), which are co-produced with brine, are significantly high in the geothermal fields of Turkey...
COMPARISON OF HOST GOVERNMENT PETROLEUM CONTRACTS AND APPLICABILITY FOR TURKEY DEEPWATER OFFSHORE LICENCES Vural, Fatih; Durgut, İsmail; Peker, Hülya; Department of Petroleum and Natural Gas Engineering (2021-5-31) In the boundaries of sovereign nations, which has a legal dominion over of its geographical area, including natural resources, the vast majority of the World’s energy sources are developed. If a country opens the resources...
Oil spill surface fate model through random walk method with drifted particles in voronoi diagram Erdoğan, Metehan; Durgut, İsmail; Department of Petroleum and Natural Gas Engineering (2021-1-11) Oil spilling isahazardous case to the marine environment by increasingthe risk of the destruction continually by flowing on the sea, expanding into sea and mixing into the air. Its potential threats can be prevented after ...
Survey calculation procedures on aegean part of turkey geothermal wells Büyükkağnıcı, Burak; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2020-10-14) Productive sections of geothermal wells generally exceed hundreds of meters which is substantially longer than that of the oil and gas reservoirs. This brings a flexibility and cost-effective solutions in the application...
Comprehensive approach to torque and lost circulation problems in geothermal wells in terms of drilling fluid Sönmez, Ahmet; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2020-7) Drilling in a lost circulation zone has long been a challenge in geothermal wells due to its strong potential for high torque and wellbore instability. Excessive torque and friction values cause overpull, pipe stuck and se...
Modeling transient flow in fractured shale reservoirs Kılıçaslan, Ufuk; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2020-7) Oil and gas production from shale reservoirs has been popular in North America for more than two decades. Commercial production from these extremely low permeability reservoirs is only achieved by multi-stage fractured hor...
The effect of experimental conditions on natural gas hydrate formation Longinos, Sotirios; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2020) Natural gas hydrates (NGH) are proposed as gas storage and transportation media owing to their high gas content and long-term stability of hydrate crystal structure at common refrigeration temperatures and atmospheric pres...
Effects of the formation to the orientation of the directional wells in the Adıyaman region Ünlü, Ahmet; Mehmetoğlu, Mustafa Tanju; Department of Petroleum and Natural Gas Engineering (2020) Directional drilling is controlling the inclination and azimuth of a wellbore to reach a predetermined underground target and is a method used widely nowadays. There are various methods for directional drilling operations ...
Matrix-fracture transfer in non-isothermal conditions Tavakkoli Osgouei , Yashar; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2020) A numerical and experimental study was carried out to investigate matrix-fracture transfer in fractured porous media. Film type heat flux sensors were installed in four different synthetically fractured core plugs to measu...
Mathematical modelling of geothermal carbon dioxide production in a specific field in Turkey. Kumsal, Beril; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2020) Turkey’s non-condensable gases production from geothermal fields is very high when compared to other countries’ average production values. A big predominance of these gases is generally carbon dioxide (CO2) and the origin ...
A new approach to reduce the formation fluid invasion during well control operations Tekdal, Gazel; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2019) Well control technique is particularly important in oil and gas operations such as drilling, well work over, and well completions because of higher drilling costs, waste of natural resources, and the possible loss of lives...
Design and evaluation of wellbore strengthening materials for fractured reservoirs Gargılı, Uğur; Durgut, İsmail; Department of Petroleum and Natural Gas Engineering (2019) The lost circulation is a primary consideration while drilling through fractured carbonate formations. Uncontrolled lost circulation may result in high nonproductive drilling time and cost, stuck pipe, side-tracks, blowout...
Assessment of the effects of carbon dioxide injection on the reservoir formation, caprock and wellbore integrity Omar, Abdirizak Ali; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2019) Climate change is currently one of the most serious issues affecting the planet earth and its population. The continuously increasing concentration of carbon dioxide (CO2) in the atmosphere is a major culprit. In efforts t...
Prediction of dog-leg severity by using artificial neural network Kaymak, Sinem; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2019) As technology growth, complexity of the drilling wells has been increasing. Directional wells have been drilling in order to deviate the well through planned targets which are at distant location from wellhead. One of the ...
A Technical approach to Saudi Arabia crude oil supply forecast and potential substitutes Aslanoğlu, Volkan; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2019) In this master thesis, crude oil production forecast of Saudi Arabia and its potential substitutes are investigated. Reservoir and production behavior of 12 giant fields and the other fields' production as a function of to...
Nanoparticle-stabilized CO2 foams to improve conventional CO2 EOR process at Batı Raman field Safran, Saibe Esra; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2019) Because of the natural fractured characteristic of the B. Raman field which is the largest field of Turkey, already existing CO2 injection system does not work at desired efficiency. Thus, the main purpose of this project ...
