Special Issue Information

Dear Colleagues,

With advancements in primary energy resource extraction technology, the production of natural gas from shale, tight, and ultra-low permeability reservoirs has significantly increased over the past two decades. This has led to an abundant natural gas supply, positively impacting availability and consumer prices, while also providing environmental benefits through cleaner energy sources. However, the production of gas from such reservoirs strongly relies on hydraulic fracturing techniques to achieve the most economic production, introducing more challenges, uncertainties, and environmental concerns. Considering the recent technological improvements such as proppant technology, fracturing fluids, geosteering and monitoring, as well as data science, artificial intelligence (AI), and machine learning (ML) technologies, this Special Issue aims to disseminate the most recent advances in hydraulic fracturing technology and shale gas reservoir modeling.

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

  • Analytical and numerical modeling for hydraulic fracturing simulation and optimization;
  • Fracture characterization and monitoring (e.g., microseismic and fiber-optic enabled monitoring);
  • Refracturing and infill well fracturing;
  • Imbibition and flow back of fracturing fluid;
  • Mathematical modeling of complex fracture networks;
  • Numerical simulation and optimization of shale gas reservoirs;
  • Uncertainty quantification and risk analysis;
  • Machine Learning applications and data-driven models;
  • Geomechanical and geochemical aspects and impacts;
  • Economics, safety, and environmental considerations.

The choke effect of hydraulic fractures on a horizontal shale oil well during production is shown using a coupled matrix–fracture–wellbore flow simulation model. The effect is the consequence of a significant loss in hydraulic fracture conductivity near the wellbore due to fracture closure stress. A consequence of the choke effect is that the fluid pressure in the fractures is maintained high enough to keep gas in the solution. The gas leaves the solution only after the choke region is passed when the oil with its solution gas begins the flow in the wellbore, and when it abruptly experiences a steep pressure gradient. This phenomenon has a long period of producing a constant gas–oil ratio (flat GOR) as its signature. The influence of the choke effect on the wellbore flow regimes is also investigated in the hydraulic-fractured horizontal section of the reservoir. During horizontal pipe flow, a distributed–intermittent flow sequence develops from the toe to the heel of the shale oil well over the production time. However, in the presence of the hydraulic fractures, a sequence of distributed–intermittent–transient–segregated flows develops. This indicates that the choke has the potential to affect the flow regimes in the horizontal section. Full article
