Abstract

Harvest Operations Corp (HOC) has drilled total of 15 producer and injector well pairs of SAGD (Steam Assisted Gravity Drainage) wells in north eastern Alberta, Canada, targeting McMurray oilsand formation. Operators in heavy oil reservoir including SAGD drilling operation often have troubles maintaining a good well integrity throughout the production. One of the most common problem operators have is steam leaking, either to a different formation or to surface, which is mostly caused from a bad cement bond quality. To improve the cement bond, HOC incorporated the unique well design, by lowering the surface casing setting depth, by using a special thermal cement blend, and by optimized cementing practice such as centralizer and stop collar design and squeezing Calcium Carbonate and Potassium Chloride solution.

Harvest Operations Corp.(HOC) 는 캐나다 알버타(Alberta) 주 북동부 McMurray 오일샌드(Oil Sand) 층을 대상으로 SAGD(Steam Assisted Gravity Drainage) 생산정과 증기 주입정 15쌍을 시추한 바 있다. 동 지역에서는 SAGD 생산시추를 비롯한 중질유 개발 회사들이 시추공 안정성 유지에 큰 어려움을 겪고 있으며, 특히 오일샌드 생산 시 낮은 시멘트 점착력으로 인해 주입된 증기가 누출되고 생산량이 감소하는 문제가 발생하고 있다. HOC는 시추공 디자인 상의 케이싱 심도변경, 특수 시멘트 적용, 최적의 시멘팅 기법 적용, 탄산칼슘 및 염화칼륨 이수 사용 등을 통해 동 문제를 해결하였다.
