Experimental investigation of the mechanism of supercritical CO2 interaction with tight sandstone
One of the important technologies for combating global climate change is CCUS (Carbon Capture, Utilization, and Storage), which aims to address the issue of “greenhouse effect” generated by a significant amount of greenhouse gas emissions.

Formation condition of deep gas reservoirs in tight sandstones in Kuqa Foreland Basin
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 Supercritical CO2 on the Formation Sensitivity of Tight Sandstone
It is challenging to get water-based fracture fluid to flow back into low-pressure gas reservoirs. In order to solve the problem, supercritical CO2 is a novel type of non-aqueous fracturing technique with a wide range of applications prospect in low ...

Two-scale analysis of a tight gas sandstone
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 ...

Effectiveness of Oil Filling in Tight Sandstone Reservoirs of Yancheng Formation in Ordos Basin
The Ordos basin is one of the important oil-bearing basins in China, with abundant tight sandstone oil resources, wide distribution, and large thickness. It is the most realistic field of unconventional oil and gas exploration in China, and it is also an
