Abstract

This paper discusses important environmental issues that must be considered during shale gas development. Shale gas has been attracting many attention as the next key energy resource with its large abundance through easily accessible production fields, and its lower carbon dioxide & sulfur dioxide emission profile upon combustion when compared to the conventional oil and natural gas resources. Successful development of a shale gas field requires the use of hydraulic fracturing to recover hydrocarbon through the very tight shale formation, which has been frequently associated with environmental contamination issue of water, soil, and atmosphere. Therefore, environmental issues and their solution to minimize environmental impact should be considered for successful development of shale play in a future.

본 연구에서는 최근 전 세계적으로 이슈가 되고 있는 셰일가스 개발 과정 중 발생 가능한 환경문제에 대해 고찰하고자 하였다. 셰일가스는 개발 가능한 자원량 측면에서 매우 우수하며, 기존의 석유 및 석탄에 비해 이산화탄소 및 아황산가스 배출량도 적은 친환경적인 연료이다. 셰일가스가 부존하는 지층의 특성상 개발 과정 중 유체투과도를 높이는 수압파쇄공법 적용이 필수적이나, 이러한 기술 적용에 따라 수질, 토양, 대기 오염 등 다양한 환경문제의 발생이 예상된다. 셰일가스 개발에 따른 오염은 지상 및 함수층 주변에서 발생 가능하며, 따라서 셰일가스 개발은 환경적으로 위험 요소가 될 수 있다. 그러므로 셰일가스 개발 시 발생 가능한 환경문제에 대한 이해가 필요하며, 본 연구에서는 향후 수압파쇄공법에 의한 셰일가스 개발 시 발생할 수 있는 주요 환경 문제들을 정리하고, 이에 대한 해결 방안들을 제시하고자 하였다.
