... of diffusive time of flight (DToF) coupled with volumetric calculations at a granular level. In our analysis, we compute the DToF for each well under two distinct scenarios: Single Development (SD) and Co-Development (CD). We logarithmically segment the pore volume into bins based on the DToF values. Building...
