Based on the tests, this technology could increase the recovery rate of crude oil by more than 20% for most of China's oilfields. The increase in crude oil would be equivalent to half of the total output in these oilfields in the past fifty years. The accepted oil sulfonate demonstration project is a high-tech industrialization project which was handed over to Sinopec by the National Development and Reform Commission. The Shengli Oilfield Administration Bureau, which oversees China's second largest oilfield that is located in Shandong's Dongying, was responsible for the concrete tasks of tackling the critical scientific and technological issues and developing the project. The project was officially put into operation on March 10, 2004, with an annual production capacity of 20,000 tons. According to test simulation results from the laboratory, this unique technology allows the production of crude oil from a ton of oil sulfonate to be increased by more than 130 tons and the recovery rate of high-permeability oilfields to be increased by 20% to 30%. Based on industrial tests at the Shengli Oilfield, the daily output of each of its ten oil wells is increased by an average of 15 tons. The current output is four times the output prior to the use of this technology. Experts who attended the project acceptance meeting believed that the technology is mature and reliable, while the techniques are reasonable and easy to use. It complies with the most advanced international standards. Through using this technology, the recovery rates of most of China's oilfields, such as Daqing, Shengli, Liaohe and Huabei, will increase by huge margins.
