Real-time gas monitoring at the Tekke Hamam geothermal field (Western Anatolia, Turkey): an assessment in relation to local seismicity
Süer, Selin; Wiersberg, Thomas; Güleç, Nilgün Türkan; Erzinger, Joerg; Parlaktuna, Mahmut (Springer Science and Business Media LLC, 2020-08-01)
This study presents the results of a real-time gas monitoring experiment conducted, via the use of a quadrupole mass spectrometer, in a mofette field within the Tekke Hamam geothermal site in western Anatolia (Turkey), a t...
Polymer gel conformance on oil recovery in fractured medium: Visualization and verification
Canbolat, Serhat; Parlaktuna, Mahmut (Elsevier BV, 2019-11-01)
Due to complexity and heterogeneity of the geological patterns of fractured reservoirs recovery estimations are considered to be extremely challenging. These fractures form complicated paths for reservoir characterization ...
Analytical and visual assessment of fluid flow in fractured medium
Canbolat, Serhat; Parlaktuna, Mahmut (Elsevier BV, 2019-02-01)
Most reservoirs consist of natural and artificial fractures, including isolated microscopic fissures. These fractures form complicated paths for reservoir characterization and fluid movement that ultimately impacts product...
Effects of minerals on steam distillation during thermal heavy-oil recovery: An experimental investigation
Osgouei, Yashar Tavakkoli; Parlaktuna, Mahmut (Informa UK Limited, 2018-01-01)
An experimental study was carried out to investigate the role of various clay and non-clay minerals present in reservoir formations on steam distillation process. Dead oil samples (100 g) of two heavy oil reservoirs with 3...
A study on the effect of the chemical composition of brine to improve oil recovery from carbonates
Polat, Can; Parlaktuna, Mahmut (2017-01-01)
Nowadays, brines are not simply regarded as tools for pressure support in reservoirs. Their chemical properties have also been taken into consideration. Chemicals in the brines can alter the rock brine and oil interactions...
Experimental investigation of solids transport in horizontal concentric annuli using water and drag reducing polymer-based fluids
Allahvirdizadeh, Payam; Kuru, Ergun; Parlaktuna, Mahmut (2016-09-01)
When drilling long horizontal wells, drilled solids tend to settle down on the low side of the welibore and form a stationary bed. Presence of stationary cuttings bed causes operational difficulties such as pack-off, exces...
Experimental investigation of carbon dioxide injection effects on methane-propane-carbon dioxide mixture hydrates
Abbasov, Abbas; Merey, Sukru; Parlaktuna, Mahmut (2016-08-01)
In this research, first, hydrate with high saturation in porous media (sand sediments) was formed in fully filled high pressure cell by using a mixture of the following gases at 4 degrees C: methane (CH4), propane (C3H8) a...
Black Sea Hydrate Formation Conditions of Methane Hydrogen Sulfide Mixtures
Bulbul, S.; Parlaktuna, Mahmut; Mehmetoglu, T.; Karabakal, U. (Informa UK Limited, 2014-01-01)
The objective of the study is to examine hydrate formation conditions of methane-hydrogen sulfide mixtures providing the Black Sea conditions. An experimental work is carried out by using a system that contains a high-pres...
Hydrate Inhibition with PEO (Poly 2-ethyl-2-oxazoline)
Bulbul, S.; Kadoura, A. S.; Merey, S.; Parlaktuna, Mahmut (2014-01-01)
This study is aimed at investigating the effects of a poly 2-ethyl-2-oxazoline-type polymer on the prevention of methane hydrate formation. During the study, seven experiments with low concentrations of poly 2-ethyl-2-oxaz...
Hydrate Formation Conditions of Methane Hydrogen Sulfide Mixtures
Bulbul, S.; Parlaktuna, Mahmut; Mehmetoglu, T.; Karabakal, U. (2014-01-01)
The objective of the study is to determine hydrate formation conditions of methane-hydrogen sulfide mixtures. An experimental work is carried out with different H2S concentrations and both brine and distilled water. The Bl...
