Abstract: Abstract Ultrasonic velocity is a key shale gas reservoir property, especially in the context of gas production or CO 2 injection for geo-sequestration. This ultrasonic velocity reflects the dynamic elastic properties of the rock, and… read more here.

DOI: 10.1016/j.petrol.2019.03.046
Abstract: Abstract Proppant distribution is an important topic, because it is closely related to the success or failure of hydraulic fracturing treatment. Although, many proppant transport models have been published, there is still relatively limited research… read more here.

DOI: 10.1021/acsomega.0c00714
Abstract: Involving the fluid-particle hydrodynamic process and hydraulically created fracture network, fracturing-fluid flowback in hydraulically fractured shale wells is a complex transport behavior. However, there is limited research on investigating the influence of proppant transport on… read more here.

DOI: 10.1029/2020gl091357
Abstract: The transport of chemically reactive fluids through fractured clay‐rich rocks is fundamental to many subsurface engineering technologies. Here, we present results of direct‐shear laboratory experiments with simultaneous imaging by X‐ray Computed Tomography in Opalinus claystone… read more here.

DOI: 10.3390/en11113010
Abstract: Hydraulic fracturing (HF) is widely used in shale gas development, which may cause some heavy metals release from shale formations. These contaminants could transport from the fractured shale reservoirs to shallow aquifers. Thus, it is… read more here.
