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

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.

and application of alkaline-surfactant-polymer
(ASP), surfactant-polymer (SP) and polymer
flood (PF) projects as well as design of EOR
injection facilities
Keynote speakers
Dr. Wu graduated from Beijing Normal
Dr. Feipeng Wu, Ph.D. Chem. 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
Ryan. Devlin, B.Sc. Chem.
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.
Keynote speakers
Ryan has worked in the specialty chemical
Dr. Feipeng Wu, Ph.D. Chem. 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
Ryan. Devlin, B.Sc. Chem.
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
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
When to apply…
- Very high temperatures (up to~130°C)
- High salinities (up to ~300,000mg/L).
- Severe heterogeneity (0.1mD v.s. 8,000mD)
Nano-spheres are much less susceptible to geological conditions
than other chemical technologies.
Nano-sphere technology
Nano-sphere chemistry will not permanently
block the pore opening. It will continue to
advance through the less permeable zones due
to its elasticity.
Roadblock of water
Initial Pre-expansion
size 50 -100 nano meters
Post expansion Size @ <1 Micron
Nano-sphere technology
Typical example for oil water cut of injecting 6 months Nano
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
No produced fluid
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.
