Abstract null null As a reservoir stimulation technique, hydraulic fracturing is expected to be used in gas hydrate production to overcome the glaring challenge of low gas production rate. Several experimental studies have been carried out in hydrate-bearing sand, which confirmed the frackability of this kind of geomaterial. But for the fine-grained hydrate reservoir, which spreads more widely, contains the majority of the total hydrate resource, and is more difficult to exploit, there is no exp...

Hydrofracturing technology has become successful in enhancing the permeability of shale gas reservoirs. However, given the geological complexity in the subsurface, considerable challenges remain in quantitatively analyzing the hydrofracture geometry and understanding the anisotropic fracture process. To investigate, we conducted hydrofracturing tests through a horizontal borehole in shale core samples to simulate a horizontal fracturing stimulation. Based on the X-ray computed tomography scannin...

Fluid injection-induced earthquakes have been a scientific and social issue of wide concern, and fluid pressurization rate may be an important inducement. Therefore, a series of stepwise and conventional injection-induced shear tests were carried out under different fluid pressurization rates and effective normal stresses. The results show that the magnitude of fluid pressure is the main factor controlling the initiation of fracture slipping. The contribution of fluid pressure heterogeneity and ...

Abstract Soil and rock mixture (SRM) is very common in engineering as a type of extremely heterogeneous and anisotropic geological material. SRM is easy to fracture and damage under external forces, which often causes geological disasters, such as landslide and debris flow. Therefore, study on the progressive fracturing of this material is very important for geological engineering. In this paper, uniaxial compression test with real-time computed tomography (CT) scanning was conducted on SRM samp...

The Silurian Longmaxi formation in the Sichuan Basin, which is the most important gas-producing shale reservoir in China, is characterized by relatively small effective thickness, large in-situ stress difference and highly-developed natural fracture (NF) system. Microseismic monitoring shows that complex hydraulic fracture (HF) networks with relatively small height could be stimulated in the Longmaxi shale reservoirs. Traditional two-dimensional (2D) numerical models cannot capture the three-dim...

Comparing to the water fracturing fluid regularly used in the hydraulic fracturing operation, supercritical CO2 (SC-CO2) as a promising nonaqueous fracturing fluid has the great potential for the improvement of production and protection of shale reservoir. This paper presents an experimental study of the mechanical response and fracture propagation of shale fractured using water and SC-CO2 under the different stress status and injection rate. According to the experimental results, SC-CO2 fractur...

Abstract. Hydraulic fracturing is commonly used for the exploitation of shale gas. However, the mechanism of permeability increase after the fracturing has still remained unclear so far. In this study, a hydraulic fracturing experiment was performed on Longmaxi shale specimens in order to create the hydraulic fractures. In order to investigate the cracks at micro-scale, several small slices were collected from the fractures surface and scanned with the scanning electron microscope (SEM). The reg...

Dilation behavior is of great importance for reasonable modeling of the stability of the host rock of the repository for high-level radioactive waste disposal. It is a suitable method for carrying out direct shear experiments to analyze the dilation behavior of rock with well understood physical meanings. Based on a series of direct shear experiments on granite samples from the Alxa candidate area under different normal stresses, the shear stress‒shear strain and shear stress‒normal strain relat...
