Carbon Accounting for Carbon Dioxide Enhanced Oil Recovery

Research output: Book/ReportCommissioned report

Abstract

CO2EOR is an available technology that can be used to produce incremental oil from depleted fields whilst permanently storing large volumes of the injected CO2. Although this technology has been used successfully in North America for a number of decades there are currently no CO2EOR projects in the UKCS.

In this study two theoretical CO2EOR cases were modelled to allow a medium to high level life cycle analyses of greenhouse gases involved in the process to be studied. The study focused on the operational phase of a development where +99% of greenhouse gases are thought to be associated. Although the two modelled scenarios share much of the same design structure, the period of continuous CO2 import was varied from 10 years (case1) to 20 years (case 2) between the two cases. Some of the key findings of the study are presented below.
