Abstract

This paper presents a case study on well completion and hydraulic fracturing optimization strategy using an integrated engineering approach to a pair of horizontal wells in a tight gas condensate reservoir. Both of horizontal wells drilled parallel to each other have some differences in the fracture geometry and production even though they were completed and hydraulically fractured in a similar way as well as geographically close. The heterogeneous and anisotropic reservoir characteristics in lateral sections can be presumed as one of the critical factors causing the differences, but verification is needed. Therefore, the integrated engineering approach was applied not only to verify whether reservoir characteristics critically affects fracture and production performances but also to examine the feasibility of setting up the development optimization strategy.

본 논문은 치밀가스 콘덴세이트 저류층에 시추된 2공의 수평정을 대상으로 공학기반의 통합접근방식을 이용한 유정완결 및 수압파쇄공법 최적화 전략에 관한 사례연구를 제시하고 있다. 평행하게 시추된 두 유정은 지리적으로 인접할 뿐만 아니라 유정완결 및 수압파쇄공법이 유사하게 적용되었음에도 불구하고 균열 및 생산거동은 다소의 차이를 보이고 있다. 이는 불균질하며 이방적인 저류층 특성이 주요요인 중 하나일 것으로 추정되나 검증이 필요하다. 이에 따라 균열 및 생산거동에 영향을 끼치는 주요인자가 저류층 특성인지를 검증함은 물론 개발최적화 전략 수립의 가능성을 진단해 보고자 공학기반의 통합접근방식을 적용하였다.
