CO2-PENS: A CO2 Sequestration Systems Model Supporting Risk-Based Decisions
XVI International Conference on Computational Methods in Water Resources
2006
2006
The Zero Emissions Research and Technology (ZERT) project at the Los Alamos National
Laboratory is studying the injection of
CO2 into geologic repositories. We are formulating the problem as science based
decision framework that can address issues
of risk, cost, and technical requirements at all stages of the sequestration process.
The framework is implemented in a sys
tem model that is capable of performing stochastic simulations to address uncertainty
in different geologic sequestration sc
enarios, including injection into poorly characterized brine aquifers.
Processes level laboratory experiments, field experiments, modeling, economic data,
and risk theory are used to support the
system level model that will be the basis for decision making. The current system
model, CO2-PENS, is already proving to b
e useful in showing complex interactions between the different components of the
framework. The system model also provides a
consistent platform to document decisions made during the site selection,
implementation, and closure periods.
