A review of SAGD technology development and its possible application potential on thin-layer super-heavy oil reservoirs

Super-heavy oil is a significant unconventional energy source, and more than 30 years of research have shown that steam-assisted gravity drainage (SAGD) technology is suitable for thick super-heavy oil reservoirs. Recently, more and more thin-layer super-heavy oil reservoirs have been discovered in China, while their deep buried depth and serous heterogeneity make the existing SAGD technology difficult to apply, so it is urgent to improve the existing SAGD technology for the thin-layer super-heavy oil. To this end, this paper focuses on the enlightenment of field application in SAGD technology. Firstly, based on typical SAGD field projects, the development history of SAGD technology in the world was reviewed, and the influence of reservoir physical properties on the application of SAGD technology in thin-layer super-heavy oil reservoirs was analyzed. Secondly, the well pattern, wellbore structure, pre-heating, artificial lift, and monitor technique of SAGD were detailed described, and their adjustment direction was expounded for the development of thin-layer super-heavy oil reservoirs. Lastly, the gas- and solvent-assistant SAGD were comprehensively evaluated, and their application potential in thin-layer super-heavy oil reservoirs was studied. The research results can provide theoretical guidance for the application of SAGD technology in thin-layer super-heavy oil reservoirs.

Stories of space and subjectivity in planning the Multimedia Super Corridor

The Malaysian government has embarked on an ambitious refashioning of the nation called Vision 2020 in pursuit of its goal of becoming a ‘developed country’. A pivotal component of this ‘vision’ is the planning and provision of information technology (IT) infrastructure in a multi-billion dollar urban mega-project called the Multimedia Super Corridor (MSC). The purpose of my paper is twofold. First, I situate an official planning document for the MSC entitled Physical Design Guidelines for the Multimedia Super Corridor in the activity of transnational planning practice. Second, I argue that a thematic series of organizing planning concepts and practices can be identified in this document. These concepts and practices work in two ways: first, by representing highly positioned notions of sub-urban, middle-class urban design conventional in specific North American cities as universally applicable to, and desirable for, the broader national development goals the MSC is intended to lead; second, by creating a ‘total image’ for the MSC that suggests an apparently seamless relationship between the MSC and the proper citizens for it at every imaginable scale. One important effect of these plans is the material transformation of a rural landscape of and for production into an urban landscape of and for consumption. This transformation raises the question of who can belong to the ‘nation’ being (re)imagined via the MSC.
