Abstract

This paper developed the simulation model of a site for a CCS project in Williston, Canada and investigated the optimal injection scenario of CO₂. Geological model was developed using two well data and 3D seismic data. It was indicated from the geological model that the properties of the aquifer were very poor with the average porosity of 4.4% and the average permeability of 0.94 md. The simulation study identified the optimal injection rate of CO₂ less than the initial target due to the poor quality of the formation. In addition, this paper provided the information for the optimal injection rate and cumulative injection amount of CO₂ according to the aquifer sizes and injection periods for the particular CCS site.

이 연구에서는 캐나다 윌리스톤 분지 내에 있는 CCS 프로젝트 사이트에 대한 시뮬레이션 모델을 구축하고 CO₂의 최적 주입시나리오를 분석하였다. 두 개의 시추공 자료와 3D 탄성파 자료를 사용하여 지질학적 대수층 모델을 구축한 결과 평균공극률 4.4% 및 평균유체투과도 0.94 md로 낮은 품질의 대수층이 확인되었다. 저품질의 대수층으로 인해 초기 계획되었던 CO₂ 주입유량보다 작은 적정 유량을 시뮬레이션을 통해 산정하였다. 향후 해당 대수층에 CO₂의 최적주입 설계를 위해 대수층의 규모와 주입기간에 따른 CO₂의 적정 유량 및 누적 주입량에 대한 자료를 구축하였다.
