In recent years, it has been determined to exist mature petroleum hydrocarbons in the Karakaya complex units which broadly spread over Northern Turkey and some of the Upper Paleozoic and Triassic sediments in the Karaburun Peninsula have shown similarity with the sandstones of the Karakaya complex. Besides, there are mercury deposits that were operated in the Karaburun Peninsula in the past and the surface and subsurface waters in the regions where mercury deposits are located contain high concentrations of mercury. It is known that the formation waters of gasfields contain high concentrations of mercury as well. For these reasons, in this study, it is aimed to investigate the oil and gas potential of the Karaburun Peninsula by conducting Total Petroleum Hydrocarbons (TPH) analysis on the samples taken from the water resources. As a result of the analyses conducted, the hydrocarbons have been detected in all the water samples. The organic geochemical methods have been used to determine the source of hydrocarbons detected in the water resources. The detected n-alkane hydrocarbons are the mature petroleum hydrocarbons and the presence of these hydrocarbons is evidence for the existence of a working petroleum system in the study area. The main structure in the maximum depth of 220 m determined in the study area has a very high potential to become an oil and/or gas reservoir according to gravity and magnetic data and because of the presence of waters containing mature petroleum hydrocarbons. Keywords: reservoir-targeted oil and gas exploration, TPH in water analysis, hydrocarbon-rich water, mercury deposit, mercury mineralization.
