Description

Unconventional oil/gas reservoirs have poor physical properties, low formation energy, and complex oil-water distribution, resulting in poor economic benefits. They require large-scale hydraulic fracturing to form effective productivity. The goal of hydraulic fracturing is to form fracture networks, increase the stimulated reservoir volume, and thereby increase the reservoir drainage area and ultimate recovery.

The formation, propagation, and interaction of induced fractures from hydraulic fracturing are comprehensively affected by oil/gas reservoir geology (initial in-situ stress, rock mechanics, rock failure criteria, deposition conditions, etc.) and engineering parameters (fracturing fluid properties, perforation point positions), etc. The geology situation, including sedimentary process and evolution, rock architecture, subsurface lithology, and rock type, have a decisive influence on the propagation and distribution of induced fractures. The complex mechanical process is a hot and difficult point in current petroleum geology research. In recent years, scholars have conducted research on this problem through theoretical analysis, numerical simulation, physical experiments, and simulation, and made great progress.

This Special Issue aims to present recent advances in various subjects addressing propagation and distribution of induced fractures from hydraulic fracturing in deep unconventional oil/gas reservoirs. We invite investigators to contribute their new work that will explore as many aspects as possible in recognizing reservoir geology and modeling of unconventional reservoirs. In addition, review articles about recent advances of propagation and distribution of induced fractures in hydraulic fracturing are also welcome.

Potential topics include, but are not limited to the following:

  • Sedimentary process and evolution in the continental basins
  • Rock architecture analysis and reservoir characterization
  • Propagation of induced fractures influenced by subsurface lithology
  • Propagation criterion of induced fractures in different rock types
  • Mechanical mechanism analysis for induced fracture network propagation
  • Natural fracture characterization with analytical/numerical methods
  • Initiation and propagation criteria for fracture propagation
  • Hydraulic/induced fracture propagation simulation
  • Parameter description and characterization method of fracture network structure
  • Fluid-solid coupling simulation model for fracturing fluid

Papers are published upon acceptance.
