Abstract

The Grosmont Formation in Canada is a fractured carbonate reservoir containing more than 400 billion barrels of bitumen. This study investigates the effect of matrix permeability, fracture permeability, and fracture spacing of carbonate rocks on the commercial feasibility of Steam Assisted Gravity Drainage (SAGD). A dual permeability model was used to conduct SAGD simulations and the commercial applicability of SAGD was analyzed using Simple Thermal Efficiency Parameter (STEP) as an economic indicator of SAGD projects. Our results confirm that the economic feasibility of SAGD implementation is influenced by matrix permeability, fracture permeability, and fracture spacing shape. In particular, increase in fracture spacing leads to decrease in economic feasibility.

캐나다 Grosmont 층은 탄산염 균열 저류층으로 4천억 배럴 이상의 비튜멘이 부존되어 있다. 이 연구에서는 탄산염암 및 균열의 특성이 SAGD(Steam-Assisted Gravity Drainage) 기법의 상업성에 미치는 영향을 파악하였다. 이를 위해 이원투과도모델을 적용한 SAGD 시뮬레이션을 수행하였으며, SAGD 프로젝트의 경제성 지표인 STEP(Simple Thermal Efficiency Parameter)을 사용해 SAGD 기법의 상업적 적용성을 분석하였다. 시뮬레이션 결과 SAGD의 경제성을 확보하기 위한 매질과 균열의 유체투과도의 관계를 파악하였으며, 균열간격이 증가할수록 SAGD 기법의 경제적 지표가 감소하는 것을 확인하였다.
