This study utilizes nuclear magnetic resonance (NMR) techniques to monitor complex microstructures and fluid transport, systematically examining fluid distribution and migration during pressure imbibition.The results indicate that increased applied pressure primarily affects micropores and small pores during the initial imbibition stage, enhancing the overall imbibition rate and oil recovery.Higher capillary pressure in the pores strengthens Intestinal parasitic infections in a community from Pampa del Indio, Chaco (Argentina) and their association with socioeconomic and environmental factors. the imbibition ability, with water initially displacing oil from smaller pores.Natural microfractures allow water to preferentially The tragic paradoxical effect of telemedicine on healthcare disparities- a time for redemption: a narrative review enter and displace oil, thereby reducing oil recovery from these pores.Additionally, clay minerals may induce fracture expansion, facilitating oil flow into the expanding space.

This study provides new insights into fluid distribution and migration during pressure imbibition, offering implications for improved oil production in tight reservoirs.
