Fabrication of fracturing fluid with cationic surfactants and carboxymethyl hydroxyethyl cellulose

The surfactant-polymer-based (S/P) fracturing fluid combines the advantages of surfactant-based and polymer-based fluids. In this study, synergistic tackifying cationic surfactants carboxymethyl hydroxyethyl cellulose potential application in hydraulic was investigated. Firstly, cetyltrimethylammonium chloride (CTAC) salicylic acid (SA) with a weight ratio 4:1 were optimized as main agent small molecule surfactant gel, which then mixed 2-hydroxyethyl ether (CMHEC) to obtain S/P gel. proppant suspension performance, gel-breaking properties, salt-resistance thermal stability evaluated confirm their fluid. These results showed that performance system much better than also polymer
