Carbon dioxide has been used commercially to recover oil from reservoir by enhanced oil recovery technologies for over 40 years. Currently, the CO2 flood is the second most applied enhanced oil recovery (EOR) processes in the world behind steam flood. Water alternating gas (WAG) injection has been a popular method to control mobility and improve volumetric sweep efficiency for CO2 flooding. The...

Miscible gas injection is one of the most effective enhanced oil recovery techniques and minimum miscibility pressure (MMP) is an important parameter in miscible gas injection processes. The accurate determination of this parameter is critical for an adequate design of injection equipment investment prospect. The purpose of this paper is to develop a new universal artificial neural network (U-A...

Anthropogenic effects on climate can be mitigated through various measures, among them being CO2 sequestration in geological media. Geological sinks for CO2 do not need any major new technological development; the technology exists and has been applied for other uses. The challenge is rather to identify the most appropriate methods and sites for long-term sequestration. There are several potent...

Injection of CO2 in geological reservoirs or deep aquifers is nowadays studied to regulate the global warming by limiting the amount of greenhouse gases emitted by human activity into the atmosphere. CO2 is captured from exhaust gas in power plants or industrial units and then stored in underground geological reservoirs. The experience available in the oil industry concerning CO2 injection clea...

The potential for hypervelocity boundary layer stabilization was investigated using the concept of damping Mack’s second mode disturbances by vibrational relaxation of carbon dioxide (CO2) within the boundary layer. Experiments were carried out in the Caltech T5 hypervelocity shock tunnel and the Caltech Mach 4 Ludwieg tube. The tests used 5-degree half-angle cones (at zero angle of attack) equ...

In addition to efforts aimed at reducing anthropogenic production of greenhouse gases, geological storage of CO2 is being explored as a strategy to reduce atmospheric greenhouse gas emission and mitigate climate change. Previous studies of the deep subsurface in North America have not fully considered the potential negative effects of CO2 leakage into shallow drinking water aquifers, especially...

Glossary Carbon sequestration: capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere. Carbon sources: for this chapter, we are concerned with large stationary sources of CO2, e.g. fossil fueled power plants, cement manufacturing, ammonia production, iron and non-ferrous metal smelters, industrial boilers, refineries, natural gas wells. Carbon captur...

A pilot carbon dioxide (CO2) sequestration experiment was carried out in the Michigan Basin in which 10,000 tonnes of supercritical CO2was injected into the Bass Island Dolomite (BILD) at 1050 mdepth. A passive seismic monitoring (PSM) network was operated before, during and after the 17-day injection period. The seismic monitoring network consisted of two arrays of eight, three-component senso...
