Abstract: A fracture network as the main channel of seepage and heat transfer has been a key focus in an enhanced geothermal system. The fractures in the geothermal reservoir usually have a strong multiscale nature in length, but ...

Abstract: Hydraulic fracturing through a multiborehole cluster is a crucial technology for the enhancement of shale gas reservoir production. However, the impact of borehole interference and in situ stress on hydraulic fracturing ...

Abstract: Thermal–mechanical damage is an important feature of natural rock containing internal defects (microcracks and microvoids). However, this damage has not been studied thoroughly. This study improved a statistical damage ...

Abstract: This study focuses on the nonlinear flow characteristics of a single rough-walled fracture in a marble sample subject to various confining pressures (5.0–50.0 MPa) and deviatoric stresses (0–60.0 MPa). First, a series of ...

Abstract: To study the blast-induced dynamic response of jointed rock mass under high geostress field, a numerical model for the blast in the jointed rock mass was first established based on Ansys LS-DYNA software and the ...

Abstract: This study is interested in executing an optimal wavelet transform (WT) to interpret the continuous leak acoustic emission signal precisely. Thus, this paper proposes detailed guidelines on how to select an optimal mother ...

Abstract: The polymer antiseepage wall is a new technology for the reinforcement of earth dams. It has the advantages of being efficient, ultrathin, minimally invasive, and economical, which makes it even more popular and widespread ...
