Shell Oil Corporation has developed an in-situ process for shale oil recovery that uses electric heaters to heat oil shale deposits and produce chemical reactions within the shale that can liberate the shale-oil. The major production expense is electrical power used to heat the shale. Significantly, small mobile nuclear reactors are now under development and testing that could provide high-temperature working fluids (both gaseous and liquid) at lower unit energy cost to replace current electrical heating. Nuclear generated steam is particularly cost effective and technically attractive for oil shale recovery. Estimates are that US oil shale deposits could be made to produce about 2 million barrels of oil per acre ($200 million/acre of oil at $100/barrel) if properly processed using high temperature steam. Furthermore, a these small nuclear reactors could be delivered by heavy haul truck, carefully buried for adequate shielding and safety, remotely operated, and moved as needed to process large oil shale fields.

The single model of oil shale development, which is, burning in boiler for power generation and distillation for shale oil, may cause enormous waste of oil-gas resources and semi-coke. For energy conservation and efficiency improvement, it is necessary to realize the comprehensive utilization of oil shale. The development of experimental system is foundation of further studying. In the paper, an experimental system for comprehensive utilization of oil shale is designed and realized. These includes: spouted bed combustor and shale ash collection system, oil shale retort with solid heat carrier and shale oil recovery system. With the system, the realistic simulation under different condition such as different kinds of oil shale, operation condition can be studied. This work lays an experimental foundation for the further study of comprehensive utilization of oil shale.

The massive use of fossil fuel has caused huge carbon emission and serious air pollution in China. Now all kinds of alternative energy technology are developing rapidly to solve such problem in China. Electricity produced by non-fossil fuel energy is continued to increase sharply in China. But it’s hard for regular alternative energy, such as wind power, solar power, hydroelectricity power, nuclear power and so on, to easily provide process heat for industry, especially high temperature steam. High temperature Gas-cooled Reactor (HTGR, sometimes also called HTR) is a kind of nuclear reactor, which are demonstrated very high efficiencies, safety and availability features by American and German power plant. HTR differs from water nuclear reactors by offering a high thermal efficiency for electricity generation and a high level of passive safety features. Now HTR-PM project is built in Shidao Bay of China. Moreover, HTR is the only nuclear reactor, which can provide high temperature steam comparing with other water nuclear reactors. So HTR can provide a versatile cogeneration solution for industry. In this paper, a case was studied, how to provide heat for a refinery and petro-chemical plant with HTR. Firstly, the energy need of a typical large chemical plant in china was investigated. Steam supply diagram of an oil refinery plant, which produced 10 million tons oil products and 1 million tons ethylene in China, was calculated. Secondly, technical feasibility of energy providing by HTR cogeneration plant was discussed. Extraction steam from HTR system was designed for the chemical plant. It would meet the requirement of steam supply for chemical plant and would replace the captive power plant, where coal was burning. The balance of steam, enthalpy and temperature was calculated. At last, economic evaluation for such cogeneration plants was carried out. The steam supply cost from captive coal power plant and HTR cogeneration plant was compared. Some economical conclusion was made from the discussion.

Summary In this study, the effects of viscosity-reducer (VR) concentration, salinity, water/oil ratio (WOR), and temperature on the performance of emulsions are examined on the basis of the selected VR. Different VR-injection scenarios, including single-VR injection and coinjection of steam and VR, are conducted after steamflooding by use of single-sandpack models. The results show that high VR concentration, high WOR, and low salinity are beneficial to form stable oil/water emulsions. The oil recoveries of steamflooding for bitumen and heavy oil are approximately 31 and 52%, respectively. The subsequent VR flooding gives an incremental oil recovery of 5.2 and 6.4% for bitumen and heavy oil, respectively. Flooding by steam/VR induces an additional oil recovery of 8.4–11.0% for bitumen and 12.1% for heavy oil. High-temperature steam favors the peeling off of oil and improving its fluidity, as well as the in-situ emulsions. VR solution is beneficial for the oil dispersion and further viscosity reduction. The coinjection of high-temperature steam and VR is much more effective for additional oil production in viscous-oil reservoirs.

The oil-shale-dreg is the wastes after refining the oil shale to obtain the shale oil. But in the oil-shale-dreg, there are the massive mineral component, like the quartz, the feldspar, the clay ingredient and so on. After calcined, its structure becomes loose, owning the very low density and much ignition loss. In our study, we use different rate of oil-shale-dreg, bauxite and flux for granulation by using disk granulator. After high temperature we get low density Petroleum Proppant. The proppants have the high strength and the high flow conductivity. That is satisfied the national standards by adding 30% wt solid waste oil-shale-dregs residue to the bauxite.
