Micro-scale pore-throat distributions in tight sandstone reservoirs and its constrain to movable fluid

Shiyou shiyan dizhi, 2021
To understand the constrains of multi-scale microscopic pore-throat distributions to the movable fluid in tight sandstone reservoirs, high-pressure mercury injection and nuclear magnetic resonance (NMR) were employed to obtain the distribution ...

Formation condition of deep gas reservoirs in tight sandstones in Kuqa Foreland Basin

Petroleum Research, 2018
Due to the high expense of deep oil and gas exploration, prediction of gas-bearing properties before drilling is crucial for deep gas reservoir of tight sandstone. Deep tight sandstone gas fields in Kuqa Foreland Basin are characterized by high abundance,

Influence of Microcracks on Stress Sensitivity in Tight Sandstone [PDF]

Lithosphere, 2021
Abstract Stress sensitivity occurs throughout the reservoir development process, especially in the study of low permeability tight reservoir, considering the influence of stress sensitivity is particularly important. When studying stress sensitivity, the current main experimental methods are variable confining pressure and variable fluid

Two-scale analysis of a tight gas sandstone

Physical Review E, 2016
Tight gas sandstones are low porosity media, with a very small permeability (i.e., below 1 mD). Their porosity is below 10%, and it is mainly composed of fine noncemented microcracks, which are present between neighboring quartz grains. While empirical models of permeability are available, their predictions, which do not compare well with macroscopic ...
