Abstract
Methods and systems for determining reservoir permeability of a subsurface formation and fracture surface area. The method includes creating a first hydraulic fracture and a second hydraulic fracture in a horizontal well, generating a pressure pulse at the first hydraulic fracture, monitoring, using a first pressure gauge the pressure at the first hydraulic fracture, monitoring, using a second pressure gauge, the pressure pulse at the second hydraulic fracture, repeating this test at different locations along the wellbore to evaluate heterogeneity in permeability and variations in fracture surface areas, analyzing pressure and rate data to determine either permeability or fracture surface area by using: analytical/numerical simulation models, or physics-based proxy models inputting pressure front/peak arrival time or peak pressure.
