Senior Engineer

Safety, Environment, and Technology Supervision Research Institute of Petrochina Southwest Oil & Gasfield Company

Dr. Yang is currently a senior engineer at Safety, Environment, and Technology Supervision Research Institute of Petrochina Southwest Oil & Gasfield Company where he leads a team of professionals managing gas field industrial wastewater. He graduated from China University of Petroleum (Beijing) and University of Calgary (Canada) as a joint Ph.D in 2016 and graduated from Sichuan University (China) as a postdoctor majoring in environmental engineering in 2018.
For the last 15 years, Dr. Yang has been involved in shale gas flowback water management and treatment technology, and he undertook about 10 important science and technology projects of provincial and bureau levels. Based on the research, he published near 20 papers in Science Citation Index journals and obtained about 10 intellectual property rights like national invent patent, standard and software copyright. Specially, the adaptive processing technology of shale gas flowback water for reuse he researched has been identified by the Academician of Chinese Academy of Engineering to reach the international leading level.
The technologies, water treatment chemicals and equipments he researched has been broadly applied in water treatment in shale gas field of Sichuan basin of China and 1.7 million tons of shale gas flowback water was treated for reuse by these achievements during the last 5 years. Then he helpd his company to saved approximately 50 million US dollars which should be used to treat flowback water for discharge instead. His technologies, chemicals and equipments also thoroughly prevented flowback water becoming smelly and black during storage.
Dr. Yang has won more than 10 awards, including Technology Invention Awards of China National Petroleum Corporation (CNPC) and Awards of the Scientific and Technological Progress of China Petroleum and Chemical Automation Application Association. He also received honors from his company and government such as Advanced Worker, Advanced Person and so on. He was selected as a "Young Science and Technology Talent" by CNPC and as the reviewer of journals like Natural Gas Industry.

China has the largest technically recoverable shale gas resource in the world and Sichuan Basin is the China's largest storage of shale gas. During the last two years, the amount of shale gas flowback water was around 10 million cubic meters in Sichuan Basin. In the next five years, there will be over 30 million cubic meters of flowback water in Sichuan. Shale gas flowback fluid generally exists severe emulsification and has high content of suspended solids due to crude oil, formation water and various chemicals present in frac fluids such as surfactants，viscosifier，clay control additives，corrosion inhibitors. It is difficult to separate oil and water and remove fine suspended particles in produced liquid. In China，the emulsified flowback water is currently regarded as hazardous waste, therefore managed strictly and disposed costly. During the last two years, the cost of disposing emulsified flowback water in Sichuan was around 11 million US dollars. A novel low-cost and environmentally friendly treatment to solve this problem has been devised by developing the efficient demulsifier and water treatment agent. It has been found that the demulsification and dehydration treatment process were improved by using these efficient chemicals. Firstly, the treatment strategy is to separate oil and water, in order to reduce the amount of emulsified flowback fluid which is hazardous waste. After demulsification, the de-oiled water with high content of suspended solids and strong stability is treated to remove colloids and particles. Lastly, the treated water can meet the requirements of internal reuse standard and be recycled for another hydraulic fracking. It was the first time to apply these novel chemicals (demulsifier and water treatment agent) and technology in Sichuan shale gas field of China. The volume of emulsified flowback water was reduced by over 25% and the cost savings of disposing emulsified flowback fluid was more than 20%. The novel technique is a very promising treatment for emulsified shale gas flowback fluid. With this attractive technology, high economic benefits could be achieved and environmental pollution problem could be solved successfully when compared to conventional disposal of emulsified flowback fluid.
