Well blowout rates in oil fields undergoing thermally enhanced recovery (via steam injection) in California Oil and Gas District 4 from 1991 to 2005 were on the order of 1 per 1,000 well construction operations, 1 per 10,000 active wells per year, and 1 per 100,000 shutin/idle and plugged/abandoned wells per year. This allows some initial inferences about leakage of CO2 via wells, which is cons...

Rock wetting behaviour and CO2/brine interfacial tension (IFT) have significant impacts on enhanced hydrocarbon recovery (EOR) carbon geo-sequestration (CGS) projects. Influence of nanoparticles/surfactant solutions (NPS) flooding EOR CGS in sandstone carbonate formation been examined recent studies. But the impact NPS dioxide (CO2) methane (CH4) wettabilities organic-rich shale IFT is presentl...

Surface and Subsurface Geochemical Monitoring of an EOR-CO2 Field: Buracica, Brazil — This paper presents a surface and subsurface geochemical survey of the Buracica EOR-CO2 field onshore Brazil. We adopted a methodology coupling the stable isotopes of carbon with noble gases to investigate the adequacy of geochemical monitoring to track deep fluid leakage at the surface. Three campaigns of CO2...

Underground injection of carbon dioxide for enhanced oil recovery (EOR) is a common practice in the oil and gas industry and has often been cited as a proven method of sequestering CO2 (US DOE, 1999). Of all sequestration methods, this is probably the best understood, as carbon dioxide has been used in the oil industry for many years. Additionally, most oil fields have been relatively well char...

Vietnam plans to develop dozens of new coal-fired power generation units over the next 20 years. In order to reduce emissions, it may appear necessary to dispose of these plants' CO2 by burying it in deep underground geological formations instead of releasing it into the atmosphere, using Carbon Capture and Storage (CCS) technology. We show that CCS has a technical potential in Vietnam. To disc...
