Abstract

Oil sands are sands containing bitumen similar to crude petroleum. Oil sands had not received enough interest because of the high production cost. However, in the current record-high oil price situation, oil sands are considered as new sources for unconventional oil. In this study, patents analysis was performed for the technologies of production of synthetic crude oil from oil sands. The patents covered were open patents applied in Korea, US, Canada, Japan, Europe, and China. The patents were divided into five detailed technologies; mining and in-situ, extraction, upgrading, fuelling, and other technologies. For oil sands technologies, there have been steady patent applications, since the first patent was applied in 1969. The number of patents applied appeared to be affected by the variation of world oil price. The portion of patents applied in US and Canada was about 90% of the overall patents and it means 05 and Canada have led oil sands technologies. Mining and in-situ technologies, and extraction have been developed actively and occupied more than 77% of the overall patents. However, the number of patents applied for mining and in-situ technologies, and extraction has been constant or started to decrease since 2000. The number of patents applied for upgrading technologies increases recently and it shows the development of upgrading technologies is active now.

오일샌드는 원유성분이 함유되어 있는 모래로 종전에는 높은 생산비용으로 인하여 큰 관심을 받지 못했지만, 최근 초고유가 시대를 맞아 새로운 대체 원유로서 세계적으로 주목받고 있다. 본 연구에서는 오일샌드로부터 합성원유 생산과 관련되어 한국을 포함하여 미국, 캐나다, 일본, 유럽, 중국에서 공개된 출원특허를 대상으로 분석하였고, 전체기술을 채굴, 추출, 개질, 연료화, 기타 기술로 나누어 세부기술 분석을 실시하였다. 오일샌드로부터 합성원유 생산 기술에 관한 특허는 1969년에 첫 출원이 이루어진 후, 꾸준히 출원건수를 보이고 있으며 특히 국제유가변동 추이에 출원건수가 영향을 받는 것으로 나타나고 있다. 미국과 캐나다 특허의 점유율이 전체의 약 90%로 오일샌드 기술을 주도하고 있음을 알 수 있다. 전체 기술 특허 중 추출 기술과 채굴 기술이 77% 이상을 차지하여 가장 활발한 활동을 보였지만, 2000년대 이후에는 출원건수가 감소하거나 일정한 양상을 보이고 있다. 반면, 개질 기술은 출원건수가 최근 들어 증가하고 있는데. 이는 근래에 관련 기술 중 개질 기술에 대한 연구가 활발함을 나타내고 있다.
