- In hydraulic fracturing operations, interfacial tension reducing agents (chemical additives) are commonly used as an additive in the fracturing fluid. This facilitates backflow which subsequently enhances production. The paper investigates the impact of such agents on the post-fracturing production process. It demonstrates that unlike common practice, the use of such agents only enhances gas production rate for ultra-tight formations, not for all formations. This was not hitherto known and is significant because it has important implications for in-field operations. The research was sponsored by industrial collaborators: Daikin, Dong Energy, Ecopetrol/Equion, ExxonMobil, GDF, INPEX, JX-Nippon, Petrobras, RWE, Saudi-Aramco and TOTAL.
