Seminar title: A Multiscale Approach for Modeling CO2 Enhanced Oil 
Recovery and Risk Analysis

When and Where: Carraway 104, 1:30pm, Friday, 12/8/2017

Abstract:

Using CO_2  in enhanced oil recovery (CO_2 -EOR) is a promising 
technology for emissions management because CO_2 -EOR can dramatically 
reduce sequestration costs in the absence of emissions policies that 
include incentives for carbon capture and storage. This study develops a 
multiscale statistical framework to perform CO_2  accounting and risk 
analysis in an EOR environment. A set of geostatistical-based Monte 
Carlo simulations of CO_2 –oil/gas–water flow and transport in the 
Morrow formation are conducted for global sensitivity and statistical 
analysis of the major risk metrics: CO_2 /water injection/production 
rates, cumulative net CO_2  storage, cumulative oil/gas productions, and 
CO_2  breakthrough time. The median and confidence intervals are 
estimated for quantifying uncertainty ranges of the risk metrics. A 
response-surface-based economic model has been derived to calculate the 
CO_2 -EOR profitability with a current oil price, which suggests that 
approximately 31% of the 1000 realizations can be profitable. If 
government carbon-tax credits are available, or the oil price goes up or 
CO_2  capture and operating expenses reduce, more realizations would be 
profitable. The results from this study provide valuable insights for 
understanding CO_2  storage potential and the corresponding 
environmental and economic risks of commercial-scale CO_2 -sequestration 
in the potential EOR sites.
