Abstract
We model the water injection well with waterflood-induced fracture by characterizing the shrinking fracture length (SFC), variable fracture conductivity (VFC) and bi-storage behavior in fracture-falloff period.Compared to current models, the bi-storage phenomenon is discovered and validated as two straight lines with unit slope in the pressure derivate curve. The VFC behavior could cause the upward of pressure-derivative curve, which is generally recognized as the characteristic of closed boundary condition while the variable fracture-storage effect may occur because of SFL.179
