A simple parameter to optimize SAGD operating conditions

신현돈 한국자원공학회 2012 Geosystem engineering Vol.15 No.2

The steam-assisted gravity drainage (SAGD) process simulations described in this study have been optimized to have the lowest cumulative steam:oil ratio (CSOR), highest recovery factor (RF) and highest calendar day oil rate (CDOR) in order to obtain optimal operation conditions. In addition, net present value (NPV) calculations were performed for each simulation case to take the time factor into account. A simple thermal efficiency parameter (STEP), based on CSOR, CDOR and RF for the time corresponding to SOR ¼ 4, was developed to evaluate the performance of a SAGD project under optimized conditions. A linear relationship was found to exist between STEP and NPV, with a correlation coefficient in excess of 0.96for most of the cases studied. For each simulation case, highest values of NPV and STEP indicated optimum SAGD operating conditions.

Tashkent Seoul Park was completed in June, 2014, following the signing of a sisterhood relationship between Seoul City and Tashkent, the capital of Uzbekistan in July, 2010. An open competition for the design of the park was held and, based on the design, the park was completed in June and open to the public in September, 2014. Tashkent Seoul Park is more than a public park in Tashkent. The focus was on making it a starting point for offering a new model for traditional parks of Korea built abroad. Korean gardens and parks built in overseas cities are not only a landscape space but also serve as an ambassador that promotes the culture of Korea to foreigners who are unfamiliar with Korean culture. Therefore, Tashkent Seoul Park was designed to reflect the beauty and uniqueness of Korean traditional landscaping to promote the image of Korea and Seoul. As such, the design and plan was focused on the best measures to make known Korean culture through a design that sets itself apart from the landscape of Uzbekistan. To date, Korean parks or Seoul parks that have been built overseas have focused on the re-enactment of gardens and parks during the Josun Dynasty era. But with the Tashkent Park, the process of the 170,000 people from Goryeo was also reflected onto the design so that the culture and sensibilities of old Goryeo could be felt as well. Korean traditional garden design elements for the representation of the Korean identity are taken from the pilot study. This design element includes not only that of Goryeo, but also the Josun Dynasty era to allow local people to experience a general Korean traditional garden. The traditional beauty and lyricism of Korea was presented to Central Asia through the park in Tashkent so that the citizens could feel the simple yet down-to-earth beauty of Korean aesthetics. As such, the spatial experience of story-telling in Seoul Park evolves from two points of view. First, it is a spatial experience from the perspective of the Goryeo period and of foreigners. It is a continuum of a landscape experience where one can trace the sentiments of Korea and a hometown in Korea by passing through lyrical and multi-faceted spatial structures. Second, it is an experience that evolves from the viewpoint of an outsider, including the Tashkent citizens. It allows visitors to read the various methods and attitudes in an unfamiliar landscape and terrain. Through a story-telling that is reminiscent of the Silk Road through which trade with East Asia took place, visitors can interact with Korean culture in the Korean Garden and throughout the process they can feel the very Korean sentiments. This park presents the latest example of a 'Korean Garden' formed overseas and thus presents a clue to understanding the representation pattern of the Korean aspects of Korean Gardens through a study on the design strategies.

This study aims to investigate the complex planning processes and design ideas of the Gwanghwamun Plaza which was opened in 2009. The opening of the plaza was significant as it was built in order to restore the symbolic meaning of axis in the historical Joseon Dynasty that was distorted during the Japanese Imperialism. The plaza itself attracts many citizens and tourists by providing the empty ground carrying historical ambiences around. In this paper, the story of the Gwanghwamun plaza will be summarized. Particularly, the background of promoting the project will be discussed and the whole planning process will be dealt with. The plaza was realized through several stages. First, the planning stage will be reviewed. The planning stage had been a quite long process since the initial idea was discussed. Since the early 90s, the political decision of making the plaza was made through the change of people's understanding toward public space. At this stage, the city government worked together with diverse citizens and professionals to share the vision and to realize the right decision in making the plaza. Second, the design stage will be elaborated in detail. This is the second design stage. The former was the idea competition and the latter was the turn-key base. The final design scheme emphasized the restoration of symbolic axis and the forgotten Yukjo Street. The scheme consists of four zones such as history restoration zone, prospect and history representation zone, culture zone, and the urban zone. Through the whole design process, the original idea remained as it was. The design concept was "a place of memory and prospect." It emphasizes the history representation, view corridor, cultural activities platform as well as the emptiness and flexibility of the basic premise of the plaza. Finally, the construction stage will be discussed. There were some additions and omissions in the construction process. The design chances in the construction stage will be reviewed in detail. After the opening of the plaza, there were some changes in the detail design. We will discuss how and why these modifications were made. In the end, the social and cultural implication of the plaza will be discussed. The storytelling of the Gwanghwamun Plaza will contribute to the clear understanding of planning and design process of pubic places. Based on this reflection, we are able to think about some suggestions of public projects for the future.

서울 청계광장 설계 연구

청계천 주변지역은 과거부터 많은 인파가 몰리는 서울의 주요한 공간이었으며, 시민의 희로애락과 삶이 담긴 장소다. 많은 역사적 사건을 겪으며 서울의 중심을 흘러온 청계천은 생활오수에 따른 하천오염과 범람을 이유로 근대화 과정에서 역사속으로 완전히 사라지게 되었다. 그러나 2002년, 회색도시를 살리고 도시경관의 질을 향상시키려는 대규모 도시운동 프로젝트의 일환으로 서울시는 노후화된 청계천 고가도로를 철거하고, 하천을 복개하기 이전의 모습으로 되돌리기로 결정하였다. 청계천은 구도심권을 활성화시켜 다양한 문화 공간을 창출했으며, 하천을 따라 형성되는 문화적, 자연적 파동에 의하여 거대도시의 어메니티를 향상시켰다. 또한 역사성을 재생하여 시민들에게 교훈적인 기회를 제공하였다. 그 중에서도 청계 광장은 디자인과 문화적인 가치를 되찾고, 현 시대가 요구하는 도시의 환경을 만들었다. 강북과 강남지역으로 나뉘어 불균형적으로 발전되어 온 서울에서, 균형적인 발전을 제고한 청계광장은 도시공간을 디자인하는 조경가의 입장에서 매우 중요한 가치가 있으며, 이러한 사회적 촉매의 노력으로 도심 문화공간으로 재탄생된 것에 의미가 있다.
