Alkaline-surfactant-polymer flooding

The focus of more recent work has been the use of relatively low concentrations of additives in other oil recovery processes. Of particular interest is the use of surfactants (qv) as CO2 (4) and steam mobiUty control agents (foam). Combinations of older EOR processes such as surfactant-enhanced alkaline flooding and alkaline—surfactant—polymer flooding show promise of improved cost effectiveness.

Most of the concepts in this polymer reprint collection are applicable to surfactant and alkaline-surfactant-polymer floods, in which mobility control is essential. Again, space limitations prevented the inclusion of papers that focus on mobility control during chemical floods.
