Mesoscale Carbon Sequestration Site Screening and CCS Infrastructure Analysis

We explore carbon capture and sequestration (CCS) atthe mesoscale, a level of study between regional carbon accounting and highly detailed reservoir models for individual sites. We develop an approach to C0 2 sequestration site screening for industries or energy development policies that involves identification of appropriate sequestration basin, analysis of geologic formations, definition of surface sites, design of infrastructure, and analysis of CO 2 transport and storage costs. Our case study involves carbon management for potential oil shale development in the Piceance-Uinta Basin, CO and UT. This study uses new capabilities of the CO 2 -PENS model for site screening, including reservoir capacity, injectivity, and cost calculations for simple reservoirs at multiple sites. We couple this with a model of optimized source-sink-network infrastructure (SimCCS) to design pipeline networks and minimize CCS cost for a given industry or region. The CLEAR uff dynamical assessment model calculates the CO 2 source term for various oil production levels. Nine sites in a 13,300 km 2 area have the capacity to store 6.5 GtCO 2 corresponding to shale-oil production of 1.3 Mbbl/day for 50 years (about 1/4 of U.S. crude oil production). Our results highlightthe complex, nonlinear relationship between the spatial deployment of CCS infrastructure and the oil-shale production rate.
