Abstract
The foaming characteristics of a foamant to be used in the recovery of oil from a subterranean oil-bearing formation by carbon dioxide foam flooding, are determined by passing carbon dioxide through a sample of the foamant in a test cell containing a porous medium under pressure conditions simulating reservoir conditions and measuring the quantity of foam formed. The pressure drop along the cell is also monitored in order to indicate the resistance to gas flow imposed by the foam.
