Evaluation of the rheological properties and methods of preparation of novel viscoelastic surfactants as diverting agents

The unique properties of viscoelastic surfactants (VES) make them one of the essential chemicals used in oil fields. However, the temperature limitations of some VES, as well as their relatively high cost, pose significant challenges for research and chemical organizations to develop new generations of VES that effectively overcome these restrictions. This paper vastly evaluated the spent acid preparation methods and their effects on the rheological profile of VES. The data presented expressed the process of screening and examining the rheological behaviors of new VES under different temperatures and shear rates at optimum controlled pH and pressure.
