In the shale gas extraction, drilling and hydrofracturing bring large amounts of water-based
working fluid into shale reservoirs, which much affects the wellbore stability and gas …

Hydraulic fracturing is an important technology for the development of unconventional gas
such as tight sand gas. In this paper, a series of fracturing experiments were conducted on …

We use dual porosity microfluidics and fluorescence microscopy to investigate immiscible
imbibition in the pore networks formed in fractured rocks, and to identify emergent pore …

The void space geometry of rough fractures is one of most important factors controlling two-
phase flow in fractured media. This paper presents a numerical study on the effect of …

Fluid imbibition is a recognized strong phenomenon in tight shale that could greatly
influences the dynamic failure behaviors. An experimental study was carried out to account …

Well productivity after hydraulic fracturing is strongly affected by the flow behaviors in
created fracture complexity. In this study, gas flow tests were conducted in splitting fractures …

The flow behavior of the coal fracture is one of the important factors that control the
production of coal bed methane after hydraulic fracturing operation in a coal seam. In this …

Hydraulic fracturing using freshwater is difficult for the commercial exploitation of a shale oil
reservoir in Jianghan Basin with a continental saline lake basin sedimentary background …

Anisotropic flow characteristics in single-fractured tensile and shear fractures in granite
subjected to various confining stresses were investigated by experiments and experimental …

The deeply buried petroleum reservoirs are usually associated with fault zones resulting
from substantial tectonic activities. Thus, the issue of wellbore stability is particularly …
