Abstract
Geophysical exploration is basically subjected to explore natural resources. However it is applied to various areas from environmental and engineering geophysics to forensic science with the development of the exploring devices and the techniques for interpretation. Today overflowing the resource nationalism starts again to attract the attention to the exploration for natural resources including oil. And the techniques suitable for developing new energy resources such as gas hydrate and shale gas are needed. Besides, new frontier oil fields are located at deep sea or polar regions. We need high-precision data acquisition system and high-resolution imaging technique for interpretation in order to solve this problem. Therefore we have to develope the new convergence technique among not only geophysical methods but also other related scientific studies. Also it will be necessary to have 4-D exploration system for the time-lapse measurement of physical properties and to have the remote/unmanned or robotic exploration system for exploring inaccessible areas. This paper shows the state of the art and vision of potential method(gravity and magnetic), electric and EM method, and seismic method.

물리탐사는 근본적으로 자원탐사에 목적을 두고 있지만, 지금은 탐사기기 및 해석 기술의 발달로 자원탐사 외에도 환경/토목 분야에서부터 법과학 분야에 이르기까지 여러 방면에 걸쳐 적용되고 있다. 그러나 최근에 이르러 자원 민족주의가 팽배해지면서 석유를 비롯한 자원개발을 위한 탐사가 다시 주목을 받기 시작했으며, 석유의 대체 에너지자원으로서 가스 하이드레이트나 셰일 가스와 같은 새로운 에너지자원 개발에 적합한 탐사 기술이 요구되고 있다. 게다가 새로운 유전 개발은 점점 심해저나 극한지와 같은 접근이 어려운 지역을 개척할 수밖에 없는 실정이다. 이는 곧 고정밀도의 자료획득 기술과 고해상도의 자료해석 영상 기술을 요구하게 되며, 따라서 앞으로는 각종 물리탐사법뿐만 아니라 관련 학문을 아우르는 새로운 융복합화 기술을 개발하여 이에 대처하여야 할 것이다. 또한 물성의 변화를 시간별로 관측하는 모니터링 시스템인 4차원 탐사 기술과 접근이 어려운 지역 조사를 위한 원격/무인 또는 로봇탐사 시스템이 필요할 것으로 예상된다. 여기서는 크게 퍼텐셜탐사(중력과 자력탐사), 전기와 전자탐사, 탄성파탐사로 나누어, 각 물리탐사법들의 최근의 흐름과 앞으로의 비전을 살펴보고자 한다.
