Foam shows excellent liquid removal compared to the base-cases. Results also show that the type and concentration of the surfactants used...

... injection, while foam quality and velocity were controlled. Results show that most of the surfactants were interacting with oil and acid under certain shear rate. Only some specific surfactants (not used in the oil industy) resulted in more stable foam and best acid diverting jobs When water was followed...

While the design of the device that couples both these effects need to be optimized, initial series of experiments show...

A surfactant is required to form the desired oil-in-water or oil-in-brine emulsion at the oil concentrations required for economic pipeline operation.
