DOI: 10.1002/2016jb013854
Abstract: The resistivity and permeability of 3-D fracture networks have been modeled as the fractures within these networks are incrementally opened. In these models, the ratio of the rock resistivity to that of the fluid is… read more here.

DOI: 10.1007/s00024-018-1774-4
Abstract: Natural fractures are ubiquitous in the Earth’s crust and often deeply buried in the subsurface. Due to the difficulty in accessing to their three-dimensional structures, the study of fracture network geometry is usually achieved by… read more here.

DOI: 10.1007/s12517-018-3921-8
Abstract: Multi-stage fractured horizontal wells play an important role in developing shale gas reservoirs by significantly improving productivity. By considering fracture networks, gas desorption, stress-sensitive fracture permeability, and pressure-dependent gas PVT properties, an analytical model is… read more here.

DOI: 10.1016/j.jsg.2017.05.012
Abstract: Abstract Structural complexity along faults (e.g., relay zones, fault intersections and jogs) exert strong controls on fluid flow, yet few attempts have been made to quantify and visualise such relationships. This paper does that using… read more here.
