- the use of foams has been extended to naturally fractured deposits and its main application has been to control the progress of gas in finished wells near the gas-oil contact and in improved recovery processes.
- the stability of the foam plays an extremely important role and this depends on the chemical structure of the surfactant that is used to generate it, in addition to the conditions of temperature, pressure and salinity that are present in the reservoir.
- the salinity is greater than 30,000 ppm of total solids and the concentration of divalent ions such as calcium and magnesium is greater than 2,000 ppm, the stability of the foam that generates this kind of chemical families of surfactants decreases drastically.

The difference between these two large areas is a matter of size and shape; where there is no significant difference in size and none of the species acts as a host for the other, the non-covalent union between two or more species is called self-assembly.

- the foam is injected into the fractured medium with the BC1 pump, before the fractured system a transparent capillary tube (TC1) is placed to visually verify the formed foam. After the invoiced system there is also a visual cell (TC2) to identify the stability of the foam once it has passed through the invoice system. Before and after the fractured system there are two pressure transducers. 4. Gas advance control.
