Computational characterization techniques applied to pore network models by using a fast percolation algorithm

•A fast algorithm to characterize digital pore networks was developed.•Nitrogen sorption, mercury porosimetry, and cryoporometry were encoded and simulated.•Pore blocking and thermodynamic or mechanical equilibrium were considered.•The algorithm was optimized by using a Max-Heap / Min-Heap sorting technique.•Simulations for pore networks reproduce the trends of typical experimental curves.
