... Abstract The paper demonstrates that the transient flow regime in multi-fractured horizontal wells, often interpreted as linear flow, is more likely elliptical flow. Elliptical flow often cannot be distinguished from linear flow at earliest times, but the apparent transition between transient...

... Blasingame 2005 and Marongiu-Porcu, et al. 2014 should arrive at similar permeability and pore pressure estimates whenever formation linear flow appears in the AC response provided the same 2D fracture model is used. However, BC flow regimes seen on the Bourdet diagnostic plot provide direct indication of...
