Treatments sizing were also based on treatment volume per unit pressure index (Zhao, 1994; Wang, 1999; Wang, 2005), or per unit injection pressure difference (HE, 2000), or per unit water injectivity index (Feng, 1999; Huang, 2001), or per unit perforated interval thickness (Giangiacomo, 2001; Philip, 2007).
