Carbon dioxide flooding is generating interest as a promising enhanced oil recovery method. Several major oil companies have carbon dioxide injection pilot projects currently underway. The results have been good, and the potential for full-scale field injection operations is good. One of the major requirements of full-scale projects will be the development of equipment - particularly down-hole equipment - suited to carbon dioxide environments. Equipment design and materials selection must focus on the problem of equipment damage by carbon dioxide and other fluids present in the well bore. In a typical carbon dioxide flood, CO/sub 2/ is injected down the well bore of the injection well into the producing zone. The carbon dioxide is forced through the zone under pressure and mixes with the oil in the zone. Miscible displacement between oil and carbon dioxide results from hydrocarbons vaporizing from the oil into the carbon dioxide. The pressure differential of the injected carbon dioxide forces this mixture to a producing well where the fluids are brought to the surface for separation and processing.
