TL;DR: Zhang et al. as discussed by the authors investigated the relationship of factors that influence shale swelling, including initial water content, clay fraction, and confined pressure, and found that water adsorption creates higher swelling volume than moisture adsorptions.

TL;DR: In this article, an experimental study of the impact of water-based fluids on the mechanical properties of a low-clay shale is presented. But, little research has been done to investigate such effect on resource shales which mainly have low clay contents.

TL;DR: In this article, the authors investigated the influence of temperature on the mode I fracture toughness of sandstone using semicircular bend specimens and found that temperature influenced fracturing in three stages along a temperature gradient.
Abstract: This study investigated the influence of temperature on the mode I fracture toughness of sandstone using semicircular bend specimens. Fracture characteristics were studied using scanning electron microscopy and other means. The results showed that temperature influenced fracturing in three stages along a temperature gradient. In the low-temperature stage (20–100 °C), fracture toughness increases slowly, with a total increase of approximately 11%. At the medium-temperature stage (100–500 °C), fracture toughness decreases slowly, at a rate of approximately 18%. During the high-temperature stage (500–800 °C), fracture toughness was reduced by approximately 44%. The mode I fracture toughness has a clear temperature threshold (500–600 °C). Below this threshold, the fracture toughness decreases slowly. When the temperature threshold is reached, the fracture toughness decreases sharply. The sharp decrease is mainly caused by the creation of a fragmentation structure. The sandstone experiences more transgranular fracture mechanics in the low-temperature stage compared to the high-temperature stage. Above 100 °C, the mechanisms include transgranular fracturing, intergranular fracturing, thermal cracking, and mutual coupling fracturing. When the temperature exceeds 500 °C, several different fragmentation structures are seen. This research study provides significant data to evaluate fracture characteristics and rock safety and stability after heat treatment.

TL;DR: In this paper, a borehole-stability model that uniquely couples the mechanical and chemical aspects of drilling-fluid/shale interactions was developed, which allows the user to determine the optimum drilling parameters (e.g., mud weight and salt concentration) to alleviate borehole stability-related problems with oil- or water-based drillingfluid systems.
Abstract: A borehole-stability model that uniquely couples the mechanical and chemical aspects of drilling-fluid/shale interactions was developed. The model allows the user to determine the optimum drilling parameters (e.g., mud weight and salt concentration) to alleviate borehole-stability-related problems with oil- or water-based drilling-fluid systems. Chemically induced stress alteration based on the thermodynamics of differences in water molar free energies of the drilling fluid and shale is combined with mechanically induced stress. These two potentials are coupled by use of the framework of poroelasticity theory to formulate the physiochemical basis of this borehole-stability model
