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 …

The advent of low-field nuclear magnetic resonance (LF-NMR) has revolutionized the
petroleum industry by providing a swift and straightforward method for the spectroscopic …

The pore structure of ultra-low permeability sandstone (0.1 mD< K< 1 mD) is complex and
has high heterogeneity, which leads to great challenges in reservoir characterization and …

Due to the low permeability, small pore throat, and poor pore connectivity of ultra-low
permeability reservoirs, fracturing was required to improve the flow environment of oil in the …

In this paper, two sandstone cores with permeabilities of 1.7 mD and 2.6 mD were employed
and the ScCO 2 huff-n-puff processes were carried out to check the oil recovery efficiency as …

Nuclear magnetic resonance (NMR) severs as a nondestructive and relative new technique
that has been widely used in characterizing reservoir fluids and pore size distribution (PSD) …

Low-field (nuclear magnetic resonance) NMR has been widely used in petroleum industry,
such as well logging and laboratory rock core analysis. However, the signal-to-noise ratio is …

CO 2 flooding is an effective enhancing oil recovery (EOR) method that is suitable for ultra-
low permeability reservoirs. Generally, high heterogeneity and natural fracture development …

The gas content test for coalbed methane (CBM) reservoirs consists of measurements of
lost, desorbed and residual gas, and it is a crucial parameter for evaluation of such …
