Understanding water uptake of gas shales is critical for designing fracturing and treatment
fluids. Previous imbibition experiments on unconfined gas shales have led to several key …

Shale contains a lot of clay minerals. Clay minerals mainly exist in nano-and micro-meter
sized particles, and the pore structure is complex, which leads to its extremely complex …

This paper on core samples collected from the Triassic Montney Formation tight gas
reservoir in the Western Canadian Sedimentary Basin (WCSB) illustrates that operationally …

Rock wettability is a key parameter determining fluids distributions and migrations in
hydrocarbon reservoirs. In shale rocks, the widespread existence of organic matter and the …

The heterogeneous-wet state within oil and gas reservoirs introduces complex fluid
distribution and flow dynamics, which significantly impacts enhanced oil recovery and geo …

In this study of the Triassic Montney tight gas siltstone play in the Western Canadian
Sedimentary Basin petrophysical measurements of drill-core samples (porosity, pore throat …

Flowback water is usually highly saline and the salt concentration varies by time and well
location. Understanding the origin of the flowback salts is essential for evaluating fracturing …

Recent studies show that the pore network of unconventional rocks, such as gas shales,
generally consists of inorganic and organic parts. The organic part is strongly oil-wet and …

Tight oil reservoirs are an unconventional hydrocarbon resource with great potential to help
meet energy demands. Horizontal drilling and hydraulic fracturing has been extensively …

The variation in pore water distribution within gas shale reservoirs has a significant effect on
gas content, and thus on resource evaluation. However, the characteristics of water micro …
