Potentials and prospects of tar sands resources in China

Under the world situation of high crude oil price and increasing demands for energy, unconventional hydrocarbon resources such as tar sands are a big concern at present. This paper presents an overview on the reserves, resources and recovery technologies of widely distributed tar sands in China, which demonstrates a great potential. Through the analysis of the worldwide developing trend of recovery technologies of tar reservoirs, we conclude that in the near future more and more industrial scale production of tar sands will soon be achieved, the means of excavation and transportation will be better, the extraction temperature will be decreased for the sake of lowering heat losses, the in situ recovery processes will be much upgraded, and the environmental impacts will be reduced to the largest degree. Meanwhile, we analyze the prospects of tar sands in China and believe that (1)a relatively high profit will be made by oil sands recovery due to the high crude oil price, (2)many sophisticated oil sands recovery technologies such as water washing, dry distillation, the Vapex (vapor extraction), and the steam assisted gravity drainage (SAGD) processes will be developed rapidly during the period of the Eleventh Chinese National Five Year Plan, and (3)great progress made in the basic theoretical studies and in the recovery technologies will make it possible for tar sands to become one of the important unconventional hydrocarbon resources and a robust support for energy supply in China.
