DOI: 10.1007/s00603-021-02646-1
Abstract: Productivity in fractured wells typically declines when severe proppant embedment shrinks the fracture aperture and creates conductivity clogging fines. However, the mechanisms linking embedment to decline are poorly characterized. In the absence of this understanding,… read more here.
