Abstract

In the demonstration-scale offshore CO₂ storage project, the monitoring team studies geophysical and geochemical monitoring of CO₂ injections in the Yeongil Bay, in which a CO₂ test injection (about 100t) was performed in January, 2017 and further injections in larger scales are planned for 2018 and 2019. In this study, the development status of the Korea-type Hydro-Geophone OBS (Ocean Bottom Sensor) and the geochemical baseline survey (focused on some anions of sediment pore water) are suggested as the preliminary results of the pre-injection test.

포항분지 해상 중규모 실증 모니터링 연구팀은 영일만의 해상 CO₂ 주입 실증 사이트에서 주입되는 CO₂를 모니터링하기 위하여 지구물리-지화학 복합 모니터링 연구를 수행하고 있다. 이 연구에서는 주입 전 모니터링 탐사의 1차 결과로서, 지구물리 탐사에서는 한국형 Hydro-Geophone OBS (Ocean Bottom Sensor) 탐사장비 개발 현황과 3D 탄성파 탐사의 결과를, 천부 지화학 탐사에서는 주입사이트의 주입 전 지화학 베이스라인 탐사(퇴적물 공극수의 음이온)에 대한 예비결과를 제시하였다.
