Abstract
In this study, a new fracturing fluid (SPME gel) formulated with the combination of a surfactant-based viscoelastic fluid (microemulsion) and a polymer gel system is to be studied to investigate its improved characteristics with enhanced synergistic properties. CMHPG was used as polymer fluid combined with a mixed anionic-anionic surfactant system, Sodium Lauryl Sulphate and Ammonium Lauryl Sulphate to prepare a gel system with dual fluid benefits and reduced polymer loading. The formulation of the single phase viscoelastic surfactant system was obtained from pseudo-ternary phase diagram experiments to identify a microemulsion gel domain region. This formulated gel showed higher thermal stability, good rheology and proppant suspension capacity as compared to surfactant-based fracturing fluid.
