Company Background

• Chinese Academy of Sciences (CAS) was founded in
  Beijing in 1949, one month after the founding of
  the Peoples Republic of China. As the nations
  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.

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. ZLs 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.

Company Background

• Juan Carlos Trombetta (JCT Consultores) has been
  a coach and consultant to local and foreign
  companies since 2002.  Previously, Mr. Trombetta
  was the country manager for a multinational
  polymer manufacturer.  He has extensive
  experience in the development and application of
  liquid-solid separation processes, specializing
  in oilfield water treatment.  In addition, Mr.
  Trombetta has developed expertise in chemical
  enhanced oil recovery (EOR), including product
  selection 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 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.

Keynote speakers

• Ryan 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

- Very high temperatures (up to130C) - 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
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 50 -100 nano meters
Post expansion Size _at_ lt1 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.

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.
