This review presents the latest update, applications, techniques of the NMR tools in both
laboratory and field scales in the oil and gas upstream industry. The applications of NMR in …

Rigorous characterizations of fluid contents, rock/fluid interactions, and pore-size
distributions are crucial in the development of unconventional resources. As a nonintrusive …

Hydrogen is among a few promising energy carriers of the future mainly due to its zero-
emission combustion nature. It also plays an important role in the transition from fossil fuel to …

The complex and multiscale nature of shale gas transport imposes new challenges to the
already well-developed techniques for conventional reservoirs, especially digital core …

Coal seams are naturally occurring geological media offering tremendous potential for gas
storage. The wetting characteristics of coals at typical geological formations underpin a …

To elucidate the NMR response characteristics of gas-bearing shales, NMR T 2 and T 1–T 2
experiments were performed on 38 shale samples selected from the Longmaxi Formation in …

Nuclear magnetic resonance (NMR) has become a crucial technique for determining
complex fluid occurrence characteristics. However, the overlap of fluid signals limits the …

Wettability alteration would play a significant role in the hydrocarbon displacement as it can
improve oil recovery factor both in conventional and unconventional reservoirs. Therefore …

Water saturation determination is among the most challenging tasks in petrophysical well-
logging, which directly impacts the decision-making process in hydrocarbon exploration and …

After long-term water injection, many developed oilfields in the Ordos Basin, China, have
entered a period of the high water-cut stage. In waterflooded layers, formation water is a …
