Company BackgroundChinese 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.

Keynote speakersDr. 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.

Dr. Feipeng Wu, Ph.D. Chem.

Ryan. Devlin, B.Sc. Chem.

Keynote speakersRyan has worked in the specialty chemical and engineering community for 16 years, specializing in polymer chemistry and technical business development. He graduated from the University of Alberta with a Bachelor of Science degree in Chemistry and Molecular Biology. Ryan is very active in the water resources community in Western Canada and more recently, the enhanced oil recovery industry. Ryan will be our keynote speaker on the Nano-sphere technology and polymers.

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

Nano-spheres are much less susceptible to geological conditions than other chemical technologies.

- 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-sphere technologyNano-sphere chemistry will not permanently block the pore opening. It will continue to advance through the less permeable zones due to its elasticity.

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.
