Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]
, 2007 Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...

Simulation of subseismic joint and fault networks using a heuristic mechanical model [PDF]
, 2017 Flow simulations of fractured and faulted reservoirs require representation of subseismic structures about which subsurface data are limited. We describe a method for simulating fracture growth that is mechanically based but heuristic, allowing for ...

Energy Science & Engineering, 2020 The frequent occurrence of casing failure has significantly affected the development of shale gas in the Sichuan Basin. Based on engineering and geology analyses, natural fracture/fault slip leads to casing shear deformation during hydraulic fracturing ...

Quantification of potential macroseismic effects of the induced seismicity that might result from hydraulic fracturing for shale gas exploitation in the UK [PDF]
, 2014 The furore that has arisen in the UK over induced microseismicity from ‘fracking’ for shale gas development, which has resulted in ground vibrations strong enough to be felt, requires the urgent development of an appropriate regulatory framework.

Geology of the Rokko Tunnel with reference to fracture pattern
Journal of the Japan Society of Engineering Geology, 1968 The Rokko Tunnel built up in April 1967 is 2843m in length and combines Kobe with the Sanda basin in lesser distance. During its construction, geological survey with datailed mapping in scale of 1/100 was attempted and the results are summarized as follows:The wall of the tunnel consists of the quartz diorite, granite and rarely lithoidite.

Evolving force balance during incipient subduction [PDF]
, 2004 Nearly half of all active subduction zones initiated during the Cenozoic. All subduction zones associated with active back arc extension have initiated since the Eocene, hinting that back arc extension may be intimately associated with an interval ...
