A SYSTEMATIC APPROACH TO SOURCE-SINK MATCHING FOR CO2 EOR AND SEQUESTRATION

Abstract

Carbon dioxide for enhanced oil recovery (CO2 EOR) can magnify oil production substantially while a
consistent amount of the CO2 injected remains sequestrated in the reservoir, which is benefi cial for reducing
the greenhouse gas (GHG) emission. The success of CO2 EOR sequestration depends on the proper sourcessinks
integration. This paper presents a systematic approach to pairing the CO2 captured from industrial
activities with oil reservoirs in South Sumatra basin for pilot project. Inventories of CO2 sources and oil
reservoirs were done through survey and data questionnaires. The process of sources-sinks matching was
preceded by scoring and ranking of sources and sinks using criteria specifi cally developed for CO2 EOR
and sequestration. The top candidate of CO2 sources are matched to several best sinks that correspond to
added value, timing, injectivity, containment, and proximity. Two possible scenarios emerge for the initial
pilot where the CO2 will be supplied from the gas gathering station (GGS) while the H3 and F21 oil fi elds
as the sinks. The pilot is intended to facilitate further commercial deployment of CO2 EOR sequestration
in the South Sumatera basin that was confi rmed has abundant EOR and storage sinks as well as industrial
CO2 sources.
