Gas hydrate exploration studies have increased substantially since last decade. Gas hydrate reservoirs are commonly found in the marine environment and permafrost. Studies related to natural gas hydrates in the Mediterranean Basin are rare compared to those released on the continental margins of the United States of America, Japan, India, China and Korea. This study provides an evaluation of the gas hydrate potential of the Mediterranean Basin using available literature data such as scientific drilling data (Ocean Drilling Program Leg 160 and Leg 161), sediment data, geothermal data, geochemical data, gas seepage data, mud volcano data etc., It is shown that there is a high producible gas hydrate potential (~ 98.16 standard trillion cubic meter) in the Mediterranean Basin. The Eastern Mediterranean basins have the highest gas hydrate potential due to its high amount of source gas potential and lower geothermal gradient compared to those in the Western Mediterranean.

The effect of gas production from deeper conventional gas reservoirs on shallower gas hydrate layer stability: A case study in the conditions of the Sakarya gas field, Western Black Sea
Aydın, Hakkı; Merey, Şükrü (Elsevier BV, 2021-6)
Gas hydrate deposits are generally found in the shallow deepwater regions where continuous permafrost exists. The presence of water, methane and thermodynamic conditions (low temperature and high pressure) is critical for gas hydrate accumulation. Disturbing thermodynamic conditions such as depressurizing and thermal treatment are the primary processes for gas hydrate dissociation. In this study, we investigate the stability of a shallow depth gas hydrate layer in the conditions of conventional gas producti...
Natural gas hydrate potential of the Black Sea
Parlaktuna, Mahmut (2001-04-01)
The Black Sea is among the regions that have been cited in the literature as having conditions suitable for natural gas hydrate reserves. Russian scientists confirmed by seismic studies that there are five regions in the Black Sea which are highly promising for hydrate formation. In this study, conventional petroleum engineering methods are utilized to estimate the possible amount of gas available in one of the Black Sea Basins.
Investigation of gas seepages in Thessaloniki mud volcano in the Mediterranean Sea
MEREY, ŞÜKRÜ; Longinos, Sotirios Nik (2018-09-01)
Gas seepages are commonly observed in marine environment. Especially, gas seepages due to anthropogenic gas hydrate dissociation are big concerns recently. In the Eastern Mediterranean Sea, Thessaloniki mud volcano was detected. Gas hydrate stability conditions in this mud volcano is very fragile. For this reason, in this study, gas seepages were predicted by using HydrateResSim at different seafloor temperature increments varying from 1 to 5 degrees C and different sediment permeability values varying from...
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 pressure. Technically feasible, cost efficient hydrate production is one of the crucial items of the whole chain of storage and transportation of gas by means of NGH technology. This study investigated the effects of types of impellers and baffles, and the use of promoters on natural gas hydra...
Investigation of gas hydrate potential of the Black Sea and modelling of gas production from a hypothetical Class 1 methane hydrate reservoir in the Black Sea conditions
Merey, Sukru; Sınayuç, Çağlar (2016-02-01)
Gas hydrate deposits which are found in deep ocean sediments and in permafrost regions are supposed to be a fossil fuel reserve for the future. The Black Sea is also considered rich in terms of gas hydrates. It abundantly contains gas hydrates as methane (CH4 similar to 80-99.9%) source. In this study, by using the literature seismic and other data of the Black Sea such as salinity, porosity of the sediments, common gas type, temperature distribution and pressure gradient, it was estimated that up to 71.8 (...
