Thermal Field in the Sedimentary Complex of the Eastern Black Sea Region and Gas Hydrates Content in the Guria Deflection Sakvarelidze E., Kutelia G. Abstract Key words: Gas Hydrates, Thermal Field, Methane, Heat Flow, Black Sea, Guria Deflection The investigation of natural gas emission sites and gas hydrates within sediment deposits has great scientific and practical interest. Methane is 20 times less efficient as a greenhouse gas than CO2. The study showed, that gas hydrates are concentrated in the Black sea for various reasons. It is the largest anoxic basin with much higher methane concentrations than in any other marginal sea. Sediments of 10- 19 km thickness reveal a potential reservoir for methane generation and hundreds of methane emission site are known there. There are certain oil and gaseous reservoirs in this area, mainly along the eastern Black Sea shelf and Guria Deflection. It should be noted that zones of gas emissions in the Guria deflection coincide with zones of high heat flow and high temperatures in the sedimentary complex.
