5. Company Background
Chinese Academy of Science
Chinese Academy of Sciences (CAS) was founded in Beijing in 1949, one month after the founding of the People’s Republic of China. As the nation’s highest academic institution in natural sciences and its supreme scientific and technological advisory body, and national comprehensive research and development center in natural sciences and technology. In 2008, CAS spin-off companies reached 30 billion dollars and through technology transfer to local enterprises, achieved sales of 16 billion dollars.

6. Company Background
ZL designs, develops and provides chemically enhanced oil recovery (CEOR) technologies that increase the effectiveness of oil field water flooding and improves oil recovery. ZL’s produces and technology had been successfully applied to over 1000 well groups in China, at the most critical oil field conditions. Established in 1995, ZL is now the largest privately owned EOR PAM producer in China.

8. Keynote speakers
Dr. Wu graduated from Beijing Normal University in 1985, where he majored in chemistry. In 2000, he obtained his Doctoral degree from University of Tokyo. After returning from Japan, he dedicated his research to EOR chemistries and has over 11 years of experience in the EOR industry with a strong focus on salinity and temperature resistant polymer technology and Nano polymer technology. He work has led to the successful commercialization of technology in over 400 well groups in Daqing, Changqing, Shengli, Henan, Xinjiang oil fields.

10. Nano-sphere technology
Purpose of the technology:
To make reservoir more homogenous and in doing so displace the oil in the relatively low perm regions of the reservoir.
The result is an increase in oil production and a decrease in the water cut over time
- Very high temperatures (up to~130°C)
- High salinities (up to ~300,000mg/L).
- Severe heterogeneity (0.1mD v.s. 8,000mD)
When to apply…
Nano-spheres are much less susceptible to geological conditions than other chemical technologies.

11. Nano-sphere technology
water
Oil
Roadblock of water flow
Nano-sphere chemistry will not permanently block the pore opening. It will continue to advance through the less permeable zones due to its elasticity.
Initial Pre-expansion
size nano meters
Post expansion <1 Micron

12. Nano-sphere technology
Typical example for oil water cut of injecting 6 months Nano

13. Nano-sphere technology
Injection system
injection Water: current water used in the field.
Injection equipment: storage tank (or totes) valves, metering pump, and static mixer (optional).
Easy to operate.
No large initial investment.
No produced fluid treatment.

14. Salinity and temperature resistant polymer technology
Why continue the research?
Fresh water usage restrictions;
Large reservoir of high temp high salinity.
Limitation of Current polymer technology;
Polymer is still a very effective CEOR tool
To completely dissolve in high salinity water;
To maintain high apparent viscosity at high temperatures and high salinity
To provide long term thermal stability.
Objectives
Introducing the Micro-block structure PAM
Template polymerization
