- •
Ignoring the presence of two phase oil-gas flow could overestimate fracture parameters.
- •
Analytical sequential flow model overestimates drainage with time.
- •
The assumption of homogeneous fracture distributions leads to an underestimation of fracture half-length.
- •
Transient flow in small hydraulic fractures is masked by pseudo steady-state pressure depletion.
