Doğu Akdeniz’in gaz hidrat potansiyeli

Son on yılda gaz hidrat arama çalışmaları oldukça hızlanmıştır. Gaz hidrat rezervuarları yaygın olarakdenizel ortamlarda ve donmuş topraklarda bulunur. Amerika Birleşik Devletleri, Japonya, Hindistan,Çin ve Kore’de kıtasal alanlarda yapılan gaz hidrat çalışmalarına kıyasla, Akdeniz ile ilgili gazhidrat çalışması oldukça azdır. Bu çalışmada literatürde mevcut olan bilimsel sondajlar (ODP 160 veODP 161) sırasında elde edilen sediman verileri, jeotermal gradyan verileri, jeokimyasal veriler, gazsızıntı verileri, çamur volkan verileri vb. ile Akdeniz’in gaz hidrat potansiyelinin değerlendirilmesiyapılmıştır. Akdeniz’de yüksek miktarda üretilebilir gaz hidrat potansiyeli olduğu (~98,16 standarttrilyon metre küp) gösterilmiştir. Batı Akdeniz’e kıyasla Doğu Akdeniz’de yüksek kaynak gazpotansiyeli ve düşük jeotermal gradyanı olduğu için gaz hidrat potansiyeli daha yüksektir.

The Gas hydrate potential of the Eastern Mediterranean basin

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.
