Comparison of three options for geologic sequestration of CO2 - a case study for California

PDF Version Also Available for Download.

Description

Options for sequestration of CO{sub 2} are best viewed in light of the regional distribution of CO{sub 2} sources and potential sequestration sites. This study examines the distribution of carbon emissions from fossil fuel power plants in California and their proximity to three types of reservoirs that may be suitable for sequestration: (1) active or depleted oil fields, (2) active or depleted gas fields, and (3) brine formations. This paper also presents a preliminary assessment of the feasibility of sequestering CO{sub 2} generated from large fossil-fuel fired power plants in California and discusses the comparative advantages of three different types ... continued below

Description

Options for sequestration of CO{sub 2} are best viewed in light of the regional distribution of CO{sub 2} sources and potential sequestration sites. This study examines the distribution of carbon emissions from fossil fuel power plants in California and their proximity to three types of reservoirs that may be suitable for sequestration: (1) active or depleted oil fields, (2) active or depleted gas fields, and (3) brine formations. This paper also presents a preliminary assessment of the feasibility of sequestering CO{sub 2} generated from large fossil-fuel fired power plants in California and discusses the comparative advantages of three different types of reservoirs for this purpose. Based on a volumetric analysis of sequestration capacity and current CO{sub 2} emission rates from oil/gas fired power plants, this analysis suggests that oil reservoirs, gas fields and brine formations can all contribute significantly to sequestration in California. Together they could offer the opportunity to meet both short and long term needs. In the near term, oil and gas reservoirs are the most promising because the trapping structures have already stood the test of time and opportunities for offsetting the cost of sequestration with revenues from enhanced oil and gas production. In the long term, if the trapping mechanisms are adequately understood and deemed adequate, brine formations may provide an even larger capacity for geologic sequestration over much of California.
