In determining permeability of porosity media using the pulse decay technique [W. F. Brace, J.B. Walsh, and W. T. Frangos, J. Geophys. Res. 73, 2225 (1968)], the reservoir boundary condition is explored to understand its influence on the rate of pressure decay. A methodology is proposed to calculate the porous volume of the sample. A universal scaling function is identified, which depends on the characteristic time, reservoir volume, and porous volume of the sample. Experimental validation shows porosity can be recovered with the proposed theory. Limitations of the method are discussed.
