NMR‐Based Quantitative Characterization of Water Imbibition in Deep Shale Rocks Under Different Pressures and Temperatures

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Unconventional tight/shale gas reservoirs have gained significant attention in the energy sector. The importance of temperature and pressure in shale imbibition lies in their profound influence on the kinetics, rate, and ultimate amount of water uptake, which directly impacts the efficiency of gas production.
