• Examples of technical questions that call for new
  knowledge
• How many phases are present? Minimum miscibility
  pressure?
• What's the phase composition and density?
• How to account for the composition of reservoir
  fluids?
• How to account for asphaltene and wax
  precipitation?
• How to account for the molecular forces and
  their impact on recovery?
• How to account for CO2-induced effects?

Current technology crude Empirical, narrowly
specialized equations for composition, density,
viscosity, etc., need to be replaced by more and
more physically realistic and hence more
predictive models.
Deliverable Theoretical 'equation of state'
models of reservoir fluids, key to reservoir
simulation and recovery prediction and an
efficient mechanism for reducing molecular
science to practicesuch as SAFT.

UW Nano-membranes for CO2 Capture from Flue Gas
and Natural Gas
'Holy Grail' Capture the flue-gas CO2 that
causes global warming, use it to squeeze more oil
from the depleted reservoir, and seal the balance
underground after oil stops flowing.
In the process, improve the economy of CO2
separation from the gas and oil sources.

EORI Project CO2 Separation For Enhanced Oil
Recovery and Cleaner Environment
Current technology expensive Amine absorption
technology costs 40/ton CO2
Target -- 5/ton, but any gain will count.
Goal To develop novel separation materials for
energy and cost effective CO2-capture processes
specifically, to synthesize, characterize and
understand novel membranes and sorbents for
separating CO2 from flue gas, natural gas, and
other CO2 streams.
11
Key technical challenge efficient membrane
Synthesize CO2-hungry hairy 'nanoparticles'
and network them loosely in a thin film
Status Preliminary materials synthesized, patent
disclosures filed
