Development of CO2-Sensitive Viscoelastic Fracturing Fluid for Low Permeability Reservoirs: A Review

There are economic and technical challenges to overcome when increasing resource recovery from low permeability reservoirs. For such reservoirs, the hydraulic fracturing plan with development of clean less expensive fluid plays a vital aspect in meeting energy supply chain. Numerous recent published studies have indicated that research on worm-like micelles (WLMs) based viscoelastic surfactant (VES) has progressed substantially. This study looks at CO2-sensitive (CO2-SVFF), its applications, benefits, limitations, drawbacks conventional fluids. The switchable viscoelasticity CO2-SVFF system signifies how reusing this is attained. Compared surfactants, can be switched high viscosity (to fracture formation transporting proppants) (easy removal after causing fracture). effect pH, conductivity, temperature, rheological behaviors CO2-SVFFs also highlighted. Further, aid Gemini surfactants nanoparticles (NPs) concentrations improve extended stability withstand shear rates temperatures during process. These provide insight into future knowledge might lead more environmentally friendly successful low-permeability Despite increased application CO2-SVFFs, there still several (i.e., high-temperature range, pressure, salinity).
