Applications of Catastrophe Theory to Surfactant-Oil-Brine Equilibrated and Emulsified Systems

Chapter

Abstract

Catastrophe theory provides a tool to analyse the structural stability of natural phenomena involving sudden changes such as phase transition or emulsion inversion* An appropriate potential (such as Gibbs free energy) is defined as a function of a state variable, which describes an intrinsic or structural property of the system, and several control variables, which stand for the familiar composition and formulation variables (surfactant concentration, water/oil ratio, salinity, Alkane Carbon Number, etc)* Depending upon the value of the control variables, the potential vs state variable graph exhibits one or several minima, which correspond to actual or possible stable states of the system.
