Depleting oil reserves and increased costs of the oil and gas recoveries have created the need to drill in challenging formations. When drilled through, shale formations in particular always generated a wide variety of problems if conventional water-based muds are used. Furthermore, the complexity and variations in shales have compounded the task of developing suitable drilling fluids. In light of these problems, the study of shale properties and their interactions with fluids will continue to be a muchneeded source of information in drilling industry. In this study a low molecular weight quaternary amine compound, which is provided by KarKim Drilling Fluids Inc., and its mixtures with sodium and potassium chloride is investigated in the aspects of capillary suction times, hot rolling recoveries, methylene blue capacities and one-dimensional free swelling properties in order to compare performances of salts and amine compound. For all test methods quaternary amine concentration from 1% to 6% by volume were studied and seen that less amount of quaternary amine compound is needed in order to obtain close shale recoveries and shale volume change potential if compared with sodium and potassium chloride. This prevents the usage of high concentration of chlorides and hence provides environmental sensitiveness. Furthermore, it was concluded that combining an amount of salt with quaternary amine compound gives the system enhanced shale inhibition properties.

Shale Gas: Current Perspectives and Future Prospects in Turkey and the World Kök, Mustafa Verşan (2014-11-17) With the increased natural gas prices and advancement in the horizontal drilling and hydraulic fracturing technology, there is a high interest in shale gas reservoirs in the world and in Turkey. However, gas production from shale gas reservoirs is quite different than conventional gas reservoirs because permeability in shale gas reservoirs is very low and production mechanism is different due to adsorbed gas and free gas together in these reservoirs. The aim of study is to clarify shale gas reservoirs in te...
Production peformance analysis of coal bed methane, shale gas, and tight gas reservoirs with different well trajectories and completion techniques Erturk, Mehmet Cihan; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2013) The large amount of produced oil and gas come from conventional resources all over the world and these resources are being depleted rapidly. This fact and the increasing oil and gas prices force the producing countries to find and search for new methods to recover more oil and gas. In order to meet the demand, the oil and gas industry has been turning towards to unconventional oil and gas reservoirs which become more popular every passing day. In recent years, they are seriously considered as supplementary ...
Quantification of the uncertainties in shale gas reservoirs, a case study for Dadas shale formation Topçu, Görkem Yusuf; Akın, Serkan; Department of Petroleum and Natural Gas Engineering (2013) In the world of a decreasing conventional oil and gas resources and high energy prices, the unconventional gas resources has become a new focus of interest of the oil and gas industry. Especially, after the American shale gas revolution, both the industry and the economies are trying to explore and exploit their potential resources. Also, Turkey is one of the lucky countries that are known to have important shale gas resources at subsurface. Up to date, Dadas shale formation in the Southeastern Anatolian ba...
Assessing uncertainties and managing risks in shale gas projects Tuğan, Murat Fatih; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2017) New millennium’s oil industry met the production from shale oil and shale gas formations as a revolution, a game changer which certainly have taken attention of most investors. However, shale oil and shale gas projects generally have marginal economics, hence should be carefully analyzed from the economic standpoint. To analyze the economics of a shale oil or shale gas play, generating an economically recoverable resource (ERR) probability function showing the full uncertainty range is highly important. Fur...
An Experimental study of enhanced oil recovery application in limestone medium using NaOH solutions Ay, Cansu; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2014) An interest in enhanced oil recovery is increasing due to rising oil prices, rising energy consumption and insufficient oil production from conventional techniques. As an EOR technique, alkaline injection is widely used to recover the trapped oil in pore spaces. In this study,the use of sodium hydroxide (NaOH) solutions as an enhanced oil recovery technique for limestone formations in South East Turkey was investigated. Routine core analyses (porosity, permeability and grain density) and spontaneous imbibit...
