Special Issue Information

Dear Colleagues,

Global consumption of minerals and energy has greatly stimulated their extraction, putting unrelenting pressure on the more accessible resources. Demand for raw materials and energy will continue to rise along with steady global economic growth and increased population­s. Rates of consumption and limited reserves make planning for stable and sustainable long-term supply extremely problematic; so it becomes urgent to press forward toward new science—supporting technologies for extracting minerals and fossil fuels from deeper formations in sustainable and economical manner.

In recent years research has shifted to focus on the harvesting of huge unconventional resources with environment sustainability. The greatest challenge comes from very low recovery rates due to ultra-low permeability in these deep reservoirs, limiting the opportunities for commercial and large-scale exploitation. Many industries have been using hydro-fracturing for extractions of oil and gas, as well as for the emergent geothermal industry. However, conventional fracturing has its limitations, demanding vast quantities of water for example. Innovative variants of existing exploration and production methods—such as new stimulation technologies to create complex fracture networks—have potential to release vast quantities of energy from highly impermeable formations. However, attempts to realise these benefits have typically failed on some front or other, whether technical, environmental, or economic.

We call for papers exploring the science and technology of enhancing the recovery of minerals, unconventional oil and gas, and geothermal energy. We will especially welcome submissions on the following topics:

  • Constitutive modelling and numerical methods
  • Coupled thermo-hydro-chemical-mechanical processes
  • Analysis and modelling of hydraulic fracture initiation and propagation
  • Reservoir geomechanics, and wellbore and drilling mechanics
  • Flow in porous and fractured media
  • Geothermal energy extraction
  • Unconventional oil and gas extraction
  • Thermo-hydro-mechanical numerical modelling
  • Case studies of international interest
  • Thermal stimulations
  • Permeability and diffusions
  • Fragmentations theoretical developments

Methane desorption characteristics of coal under definite water pressure comprises a complex two-phase flow process. A series of mercury intrusion porosimetry (MIP) and desorption experiments at different water injection pressures are reported in this study. Three lumpy coal samples were used in desorption experiments at three different water injection pressures and at natural desorption for comparison. Samples comprising two ranks of coal were used for MIP measurements including the distribution of porosity and pore sizes. The results of this study enable the establishment of a new model that encompasses a critical theoretical pore size that is most effective for water injection into coalbeds and that can be related to water injection pressure, the length of residual water, and gas adsorption capacity. Data show that the use of different water injection pressures leads to different gas desorption capacities as well as variable time effects and degree of gas desorption. Critical pore size is therefore proposed as a new parameter that can be employed to describe high pressure water effects in the context of gas desorption and can be calculated using pore size and the volume distribution law, as well as via the moisture ratio that remains after experiments and the permanent desorption percentage.
