Abstract

The world resource volume of gas hydrates is estimated about 300 trillion cubic meters excluding the gas hydrates of onshore permafrost. If half of this volume can be producible, it is close to the total reserve of natural gas worldwide. It is anticipated that the commercial production of gas hydrates is possible after 2030 due to the slow development of production technology and recent shale gas revolution. The test production planned in May 2015 was postponed during the preparation stage due to the estimated low production volume, insufficiencies of drill hole stability and flow assurance of produced gas. The test production will be rescheduled at the end of 2018. We have to prepare the gas hydrates era by developing a new breakthrough production technology in order not to kill the outcomes obtained during the gas hydrates development program of Korea last 10 years.

육상 동토층의 가스하이드레이트를 제외한 해양의 사질형 가스하이드레이트 부존량은 약 300조 입방미터로 추산되고 있다. 이중 50%를 생산할 수 있어도 현재의 천연가스 매장량에 육박한다. 막대한 부존량을 나타내는 해양 가스하이드레이트의 상업적 생산은 더딘 생산기술 확보와 최근의 셰일가스 붐으로 인해 2030년 이후가 될 전망이다. 2015년 5월로 예정되었던 국내 시험생산은 준비 과정에서 예측된 시험생산량의 부족, 시추공 안정성 확보 미흡, 가스하이드레이트 유동성 확보 미흡 등의 이유로 연기되었으나 2018년 재추진 여부를 결정할 예정이다. 이미 확보된 에너지원인 가스하이드레이트의 개발기술을 사장시키지 않기 위해서라도 새로운 획기적인 생산기술을 개발하여 향후 도래할 가스하이드레이트 시대를 대비해야 한다.
