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 …

Several studies have been performed to model the storage and transport in organic matter
present in shale gas. However, the unconventional formation does not only contain organic …

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

Reef deposits of the Upper Devonian oil fields in the north of the Perm Krai (Russia) are a
primary hydrocarbon-bearing reservoir rock. This study provides new insights into carbonate …

Electrolysis followed by underground hydrogen storage (UHS) in both salt caverns and
depleted oil and gas reservoirs is widely considered as a potential option to overcome …

As kerogen matures over geological times, bitumen is generated inside kerogen. With
further maturation, bitumen can coat the inorganic meso-macro pores, which complicates the …

Quantification of methane content in shales is a critical parameter for estimation of their
potential gas production capacity. Traditional gravimetric methods for estimation of this …

Currently there is great interest in interpreting the 1 H NMR T 2 relaxation (ie, transverse
relaxation) of porous geological media containing both liquid-like and solid-like signals. This …

In the oil industry, there is a need for fast and non-invasive methods for determining the
bitumen content and group composition in rock samples. Determination of bitumen …

This study employed laboratory experiments to comparatively investigate the adsorption
rules of methane and carbon dioxide in the clay minerals namely illite, montmorillonite and …
